DOL-HDR, HDR, and Dolby Vision are high-dynamic range (HDR) imaging types. HDR imaging captures and displays images with a broader range of brightness and colors than standard dynamic range (SDR) imaging. This can make images look more realistic and immersive.

Comparison table of SDR, HDR, and Dolby Vision:

SDR stands for Standard Dynamic Range. It is the most common type of video format, and it is what most people are used to seeing. HDR stands for High Dynamic Range. It offers a broader range of colors and brightness than SDR, making images look more realistic and immersive. Dolby Vision is a type of HDR that offers an even wider color gamut and brightness than HDR. It is also more dynamic, which can adjust the image’s brightness and contrast scene by scene.

HDR and Dolby Vision offer several benefits over SDR, including:

• More realistic and immersive images
• Greater detail in both bright and dark areas of the image
• Improved contrast and color
• Reduced glare and blooming

However, HDR and Dolby Vision also require more powerful hardware to display correctly. Most TVs and monitors do not support HDR or Dolby Vision, and even those that do may be unable to display it at its full potential.

• DOL-HDR stands for Digital Overlap High Dynamic Range. It is a type of HDR imaging that captures multiple exposures of an image simultaneously rather than one at a time. This allows smoother transitions between bright and dark areas in the image and can help reduce noise and artifacts.
• HDR stands for High Dynamic Range. It is a type of imaging that captures a broader range of brightness and colors than standard dynamic range (SDR) imaging. This can make images look more realistic and immersive.
• Dolby Vision is a type of HDR imaging developed by Dolby Laboratories. It is a proprietary tech licensed by Dolby that offers a broader range of colors and brightness than HDR, and it is also more dynamic, meaning that it can adjust the image’s brightness and contrast scene by scene.

These three technologies offer improved image quality over standard dynamic range (SDR) imaging. However, there are some key differences between them.

• DOL-HDR is the most affordable option but offers the narrowest range of colors and brightness.
• HDR is a good middle ground between DOL-HDR and Dolby Vision and is more widely compatible.
• Dolby Vision offers the broadest range of colors and brightness and is more dynamic than HDR. However, it is also the most expensive option.

The best type of HDR imaging for you will depend on your budget and needs. Dolby Vision is the way to go if you want the best image quality.

However, if you are on a budget or your hardware does not support Dolby Vision, then HDR is a good option. And if you are on a tight budget and your hardware does not support HDR, then DOL-HDR is a good choice.

Some of the most popular DOL-HDR hardware sensors include:

• Sony IMX 766
• Sony IMX 890
• Samsung ISOCELL GN2
• OmniVision OV640
• OmniVision OV64A

These sensors offer a wide range of features and benefits, including:

• High resolution
• Wide dynamic range
• Fast autofocus
• Low-light performance

Here are some additional information about these technologies:

• DOL-HDR is a relatively new technology quickly becoming more common in smartphones and other consumer cameras. It is a powerful tool that can help improve your image quality, regardless of the lighting conditions.
• HDR has been around for a few years now, and it is becoming more widely supported by TVs and other devices. It offers a noticeable improvement in image quality over SDR, and it is a good option for those who want to improve the look of their movies and TV shows.
• Dolby Vision is the newest and most advanced HDR technology. It offers the broadest range of colors and brightness and is more dynamic than HDR. However, it is also the most expensive option and is not as widely supported as HDR.

Dolby Vision is the way to go if you want the best image quality. However, if you are on a budget or your hardware does not support Dolby Vision, then HDR is a good option. And if you are on a tight budget and your hardware does not support HDR, then DOL-HDR is a good choice.

If you are comparing sCMOS vs qCMOS sensors to understand their differences better, we have an article for you.

Two of the latest CMOS sensors prevalent today are sCMOS and qCMOS sensors. They significantly contribute to the advancement of CMOS technology.

sCMOS stands for Scientific complementary metal-oxide-semiconductor. It is a type of CMOS image sensor (CIS) with strict noise specifications. It entered its 4th generation era last year. These sensors are commonly used in applications associated with astronomy or biomedical imaging. But owing to its outstanding resolution capability, it is also now implemented in alternative vision applications.

BAE Systems’ latest sCMOS Hawkeye claims to be the foremost CMOS image sensor (CIS) to capture imagery in dull nighttime conditions. The HWK1411 is designed for unmanned platforms, battery-operated soldier systems, and targeting and surveillance applications.

During the start of 2021, Hamamatsu released details on a next-gen CIS known as quantitative CMOS (qCMOS). Developed on the ORCA-Quest camera system, qCMOS is believed to be competent in determining photon count using the industry-leading readout noise of 0.27 electrons RMS.

Suppose you want to understand why sCMOS and qCMOS technologies are significant to the military or scientific community. In that case, you should be familiar with an overview of the image sensor technology that evolved during the last couple of decades.

Overview of History of Image Sensor Technology:

For more than ten years, charge-coupled device (CCD) technology was the top choice for advanced scientific imaging technology. But, since 2009, the development in scientific CMOS image sensor technology has principally pushed CCD devices unpopular. Generally, sCMOS technology provides higher speed frame rates, lower noise, and a giant field of view.

The advancement of the CMOS image sensors began to accelerate during the 1990s. However, the first generations of CMOS technology didn’t compete with CCD on quantum efficiency (QE).

It was the year 2011 when a newer generation of sCMOS enhanced QE up to 72% – 82% and decreased the read noise to the level where sCMOS will surpass CCD in several applications. The latest technology, known as the Gen III sCMOS, has entirely overlooked the potential of CCD/EM-CCD image sensors.

In 2021, the general CMOS sensor image technology depicted better quantum efficiency and reduced read noise. Therefore, the technology above may be an appropriate alternative to sCMOS. The cost factor among the two image sensors can be 10x, so this aspect makes CMOS a clear winner from a cost perspective, especially in the most demanding biomedical image applications.

To have a clear understanding, let’s get the basic details of sCMOS and qCMOS sensors:

What is sCMOS sensor?

sCMOS is technology dependent on the next-generation CMOS Image Sensor (CIS) design and fabrication techniques. The sCMOS image sensors provide fast frame rates, low noise, broad dynamic range, high resolution, high quantum efficiency, and a giant field of view concurrently in one image.

In the preliminary phases of CMOS development, the sCMOS technology was invented to eliminate the gap between the latest CMOS sensors and traditional CCD (Charge Coupling Device) sensors.

Initially, biomedical applications were inefficient in using CMOS sensors owing to the compromises in dynamic range, read noise, resolutions, and frame rates.

But when sCMOS cameras were initially invented, they used identical design principles and fabrication techniques to CMOS sensors. Also, it included various features that assisted them in tackling the preliminary shortcomings of CMOS. Consequently, sCMOS sensors are perfect for those scientific applications where low light performance, broad dynamic range, and high fidelity are inevitable.

Image acquisition starts at the top of the sensor and reaches down, row by row. Consequently, the sensor can capture images at higher framerates with lower read noise. Note that the speed of an sCMOS camera is directly related to the number of rows and the row time (the time between capturing one row and another).

What is a qCMOS sensor?

The qCMOS sensor will attain outstanding readout noise performance through cutting-edge CMOS technologies. The detection limit under ultra-low light conditions can be enhanced using a qCMOS sensor. qCMOS image sensor technology employs three measures to guarantee maximum sensitivity. These measures are BSI (back-side illumination), DTI (profound trench illumination), and Microlens. To restrict the effects of spatial crosstalk, the qCMOS sensor camera uses a DTI structure.

The number of pixels in traditional scientific cameras is, for instance, 4.2 MP with 6.5 μm pixel size or 1 MP with 13 μm pixel size. But with 9.4 MP, the qCMOS camera offers more than double the pixel count of a high-performance Gen II sCMOS camera.

The qCMOS camera realizes the particular photon number resolving apart from the temporal photon number resolving. Moreover, these cameras are also equipped with a special mode known as ‘photon number resolving mode.’ It can output the digital data as a photon number by calculating the digital output data from the AD converter to the photon number through real-time photography.

Note that the qCMOS sensor camera is the first cutting-edge camera implemented with photon number resolving capability.

Now let’s go through Bae Systems’ latest sCMOS.

Bae Systems’ Hawkeye Enables Superior Night Vision:

The Hawkeye sCMOS features a resolution of 1.6 MP (1440 x 1104) and operates at a maximum frame rate of 120 fps. This system has an ADC resolution of 11 bits and a programmable gain of 8x, 16x, and 32x.

The pixel size is 8.0 µm x 8.0 µm. The big pixel size reduces noise, an essential requirement for sCMOS technology.

The interface includes a 4-lane MIPI CSI-2 output interface, working at 1.5 Gbps/lane, with a control interface of SPI 40 MHz. Moreover, Hawkeye consumes power of less than 750 mW @ 120 fps with the operating temperature range from -40 ℃ to +85 ℃.

To improve CMOS technology, Hamamatsu achieves a milestone with its qCMOS sensor.

Hamamatsu’s qCMOS Claims 0.27e- Read Noise:

Notwithstanding the developments of sCMOS 3.0 in 2018, which featured a readout noise of 0.7 electrons RMS, still more work needs to be done. Hamamatsu has released the ORCA-Quest, the primary scientific camera in its line-up to implement the latest qCMOS image sensor technology.

The ORCA-Quest features a readout noise of 0.43 electrons RMS (Typ.) along with an ultra-quiet scan of 0.27 electrons RMS. When it comes to the quantization of discrete photoelectrons, the readout noise is a critical parameter.

Hamamatsu invented the term “qCMOS” to express the potential of “photon number resolving.” It implies measuring light by calculating photoelectrons.

As seen from the below graph, the ability to detect individual photoelectrons vanished for a readout noise of 0.5 electrons and higher.

Hamamatsu keeps driving innovation and development for the CMOS technology by introducing the qCMOS architecture. In the meantime, Bae Systems is working on adopting sCMOS technology in many fields apart from scientific imaging.

Afar sCMOS, the industry has perceived advancements in image sensor technology for various applications in 2021.

When a network camera captures an image, the light passes across the lens and impinges on the image sensor. In addition, the image sensor also contains picture elements known as pixels which record the amount of light that falls on them.

These pixels transform the received light into a relevant number of electrons. The intensity of the light is proportional to the number of electrons generated. These electrons are converted into voltage and subsequently transformed into numbers through an A/D-converter. Consequently, the signal created by the numbers is processed through electronic circuits within the camera.

Overview of image sensors:

The original argument a decade ago for the renewal of CMOS image sensors as a competitor to CCD technology was generally based on several ideas:

1- Lithography and operation control in CMOS fabrication had reached tiers that soon would allow CMOS sensor image quality to rival CCDs.

2 – Integration of companion functions on the same die as the image sensor, creating camera-on-a-chip or SoC (system-on-a-chip) capabilities.

3 – Reduced power consumption.

4 – Decreased imaging system size because of integration and reduced power consumption.

5 – Using the identical CMOS production lines as mainstream logic and memory device fabrication, delivering economies of scale for CMOS imager manufacturing.

Currently, two key technologies are prevalent for the image sensor in a camera. They are CMOS (Complementary Metal-oxide Semiconductor) and CCD (Charge-coupled Device). The following sections explain their design and varied strengths and weaknesses.

Color filtering:

Image sensors record the amount of light from the bright to the dark region with no color information. Because CCD and CMOS image sensors are ‘color blind,’ a filter at the front of the sensor enables the sensor to allocate color tones to every pixel.

In this context, two widespread color registration techniques are CMYG (Cyan, Magenta, Yellow, and Green) and RGB (Red, Green, and Blue). Red, green, and blue are the primary colors, which, when combined in varied combinations, can generate the majority of the colors visible to the human eye.

The Bayer array represents the alternating rows of green-blue and red-green filters. It is the ubiquitous RGB color filter. Because the human eye is more sensitive to green color compared to the other two colors, the Bayer array features twice as many green color filters. It implies that when using the Bayer array, the human eye can sense more detail than when all the three colors were used in identical measures in the filter.

An alternate method to filter or record color is to use complementary colors, i.e., cyan, magenta, and yellow. Frequently, the complementary color filters on sensors are merged with green filters to create a CMYG color array. Generally, the CMYG system provides higher pixel signals owing to its broader spectral bandpass.

But, the signals should be subsequently transformed into RGB because this is used in the final image. The conversion indicates added noise and more processing. The outcome is that the initial gain in the signal-to-noise is decreased. Note that the CMYG system is not so efficient at accurately presenting colors.

Usually, the CMYG color array is used in interlaced CCD image sensors. On the other hand, the RGB system is prominently used in progressive scan image sensors.

CCD technology:

In a CCD sensor, the light impinges on the sensor’s pixels and is conveyed from the chip via one output node or merely a few output nodes. These charges are then transformed into voltage levels, buffered, and delivered as an analog signal. The particular signal is finally amplified and converted to numbers through an A/D-converter exterior to the sensor.

Specifically, the CCD technology was developed to be used in cameras. For over 30 years, the CCD sensors have been utilized. Conventionally, these sensors offered some benefits compared to the CMOS sensors, including less noise and improved light sensitivity. However, these differences have vanished in recent years.

The limitations of CCD sensors are that analog components need more electronic circuitry exterior to the sensor. Also, their production is costly and can consume up to 100 times more power than CMOS sensors. Due to the increased power consumption, there can be heat concerns in the camera. This not only influences image quality negatively but also raises the cost and environmental effect of the product.

Also, CCD sensors need a higher data rate because everything has to pass through only one output amplifier or some output amplifiers.

CMOS technology:

In the beginning, ordinary CMOS chips were deployed for imaging purposes. But the output showed poor image quality because of their inferior light sensitivity. The contemporary CMOS sensors implement a more dedicated technology. Moreover, the light sensitivity and quality of the sensors have quickly augmented in recent years.

CMOS chips provide various advantages. Contrasting the CCD sensor, the CMOS chip includes A/D-converters and amplifiers, reducing the camera expense because it comprises all the logic required to generate an image. All CMOS pixel comprises conversion electronics.

Compared to CCD sensors, CMOS sensors feature better integration possibilities and more functionality. But, this inclusion of circuitry within the chip poses a risk of more structured noise like stripes and other patterns. Moreover, CMOS sensors come with higher noise immunity, lower power consumption, a faster readout, and a smaller system size.

Calibrating a CMOS sensor in production (if needed) can be more challenging than calibrating a CCD sensor. However, technological advancement has made CMOS sensors easier to calibrate. Some of them are currently self-calibrating too.

It is allowed to read individual pixels from a CMOS sensor. This enables ‘windowing,’ which suggests that it is possible to read out the parts of the sensor area rather than the whole sensor area at once.

Consequently, a higher frame rate can be conveyed from a restricted part of the sensor; digital PTZ (pan/tilt/zoom) functionalities can also be used. With a CMOS sensor, it is also possible to obtain multi-view streaming that enables various cropped view areas to be simultaneously streamed from the sensor, ultimately simulating some ‘virtual cameras.’

HDTV and megapixel sensors:

HDTV and Megapixel technology allows network cameras to deliver higher resolution video images compared to analog CCTV cameras. This aspect implies that they expand the possibility of observing details and recognizing objects and people. This is a major consideration in video surveillance applications.

An HDTV or megapixel network camera provides a minimum of twice as high a resolution as a conventional, analog CCTV camera. Megapixel sensors are fundamental components in HDTV, megapixel, and multi-megapixel cameras. They can be used to present very detailed images as well as multi-view streaming.

Megapixel CMOS sensors are extensively available and usually less expensive compared to megapixel CCD sensors. However, there are myriad examples of costly CMOS sensors.

It is tough to create a fast-megapixel CCD sensor. It is a disadvantage and increases the complexity of developing a multi-megapixel camera through CCD technology.

Many megapixel camera sensors are usually identical in size to the VGA sensors, with a resolution of 640×480 pixels. A megapixel sensor includes more pixels than a VGA sensor. Therefore, the size of every pixel in a megapixel sensor converts smaller than that in a VGA sensor.

Consequently, a megapixel sensor is usually less light sensitive per pixel than a VGA sensor. The reason is the pixel size is smaller, and the light reflected from an object spreads to more pixels. But, this technology is swiftly enhancing megapixel sensors. Furthermore, the performance in context to light sensitivity is continuously improving.

Key differences:

A CMOS sensor includes A/D-converters, amplifiers, and circuitry for extra processing. On the other hand, in a camera equipped with a CCD sensor, several signal processing functions are carried out exterior to the sensor.

A CMOS sensor permits multi-view streaming and windowing, which can’t be accomplished with a CCD sensor. Generally, a CCD sensor has one charge-to-voltage converter in each sensor. On the other hand, a CMOS sensor has one charge-to-voltage converter in each pixel. Due to the faster readout, a CMOS sensor is more suitable for use in multi-megapixel cameras.

The latest technology advancements have eliminated the difference in light sensitivity between a CMOS and CCD sensor at a specified price point.

Detailed Comparison of CCD and CMOS sensors:

i. System Integration:

Being an old technology with a CCD sensor, it is impossible to integrate peripheral components like ADC and timers into the primary sensor. Hence, additional circuitry is required, increasing the CCD sensors’ overall size. Furthermore, specialized fabrication techniques are used in making CCD sensors, so it is expensive technology.

The camera can be incorporated into the chip or system in CMOS sensors. Hence, the CMOS sensors are very compact.

ii. Power Consumption:

CCD sensors feature higher power consumption compared to CMOS sensors due to the capacitive architecture. Various types of power supplies are required for the varied timing clocks. The typical voltage for the CCD sensors falls in the range of 7 V to 10 V.

CMOS sensors offer low power consumption compared to CCD sensors because it needs a single power supply. The range of typical voltage is usually 3.3 V to 5 V. So, for the application wherein power consumption is the key criterion, the CMOS sensor is preferable to the CCD sensor.

Since CMOS sensors feature a lower power consumption compared to CCD image sensors, the temperature within the camera can be maintained lower. Moreover, heat issues with CCD sensors can enhance interference. On the other hand, CMOS sensors can have higher structured noise.

iii. Processing Speed:

CCD sensor always needs to read out the entire image, resulting in less processing speed. It is possible to increase it using the multiple shift registers. However, this will demand additional hardware.

In the CMOS sensor, the readout for the particular area of an image is possible; therefore, its speed is higher than the CCD sensor. This speed can be further increased by utilizing the multiple column select lines. Note that the dynamic range of the CCD sensor is considerably higher than the CMOS sensor.

iv. Image distortion:

A blooming effect is visible when a CCD sensor is exposed for an extended period. With the anti-blooming technique, this blooming effect can be reduced.

In a CCD sensor, all the pixels are exposed at once. Hence, if you intend to eliminate the rolling shutter effect, all the pixels must be exposed at the same time. This is called the global shutter effect. So, these days, the CMOS sensors are equipped with global sensors. Since the entire frame is captured at once, there are no wobble, skew, smear, or partial exposure effects.

The most common kind of distortion in CMOS sensors is the rolling shutter. This is because, in the CMOS sensor, the pixels are read line by line. Hence, whenever any quickly moving object gets captured by this CMOS sensor, the rolling shutter effect becomes significantly noticeable.

All portions of a frame are not captured at a time but separately. Subsequently, all parts are showcased at once. As a result, it may add a time lag in frames. So, the images may wobble or undergo a skew effect. But, the high-end CMOS cameras contain more efficient sensors.

v. Noise and Sensitivity:

CMOS sensors have more noise owing to the higher dark currents. The reason is the charge to voltage converter circuit and amplification circuit is incorporated into the same pixel. Hence, the overall fill factor of the CMOS sensor is lesser than the CCD sensor. Consequently, the sensitivity of the CMOS sensor will be lesser than that of the CCD sensor.

In the CMOS sensor, the amplifiers used in every pixel are different. Due to that, we will notice the non-uniform amplification, which would behave as additional noise. However, the technology of this CMOS sensor has progressed so much that the sensitivity and noise of this CMOS sensor are identical to the CCD sensor.

vi. Construction:

CCD chips register the pixels (whenever light strikes) on the chip and subsequently send these pixels one by one. Hence, the time required for transmitting the pixels for one image increases. Because of continuous fetching and sending activities, the chip consumes a lot of power.

In CMOS sensor chips, the sensors themselves have plenty of inbuilt circuitry. This allows reading the pixels at the photo sensor level itself. The detailed data is sent all at once. Hence, there is no time lag, and less energy will be consumed due to this activity.

vii. Vertical Streaking:

When the CCD sensor-based cameras are used in video or live mode, they demonstrate vertical streaking. In these images, a bright vertical line is formed. Because plenty of analog sensors exist in a row, the current that overflows one of the sensors will leak to the entire row. Hence, it creates a vertical line. But, in other modes, CCD sensors don’t exhibit such characteristics.

There are no such concerns in CMOS sensors because every circuit is completely isolated from the remaining circuits on the chip.

viii. Image quality:

CCD sensors boast lower noise levels since their layout enables more pixels to be recorded over their surface. Therefore, the colors of the captured images are more vibrant. As a result, it enhances the image quality.

Conversely, due to their layout, CMOS sensors can’t accommodate more pixels over their surface. Hence, images will have low resolution, which negatively influences image quality.

Because the CCD technology is more advanced than the CMOS technology, the image quality is better. But the drawback of the technology is its higher power consumption and streaking issues.

ix. Application:

CCD sensors are widely used in DSLR cameras. Conversely, due to lower cost and longer battery life, CMOS sensors are extensively used in mobile phones, tablets, digital cameras, etc.

CCD vs CMOS Sensor:

Conclusion:

CCD and CMOS sensors feature unique benefits. Both these technologies are rapidly evolving. The best suitable strategy for a camera manufacturer is to assess and test sensors for every camera being developed constantly. Subsequently, whether a selected sensor is based on CMOS or CCD becomes irrelevant. So, the only focus is the sensor that can be utilized to build a network camera that conveys the expected image quality and meets the customers’ video surveillance needs.

You can use a CCD sensor to benefit from better image quality and lower cost. You can use a CMOS sensor to help from faster readout speed, low power consumption, lower noise, longer battery life, and no time lag.
