Webcams with built-in microphones cannot always eliminate the background noise or offer clear audio output. On the other hand, separate, dedicated microphones can easily do that. The webcams with built-in microphones can’t fulfill your high-quality audio output expectations.

The reason is the quality of that built-in microphone is average. Especially you can’t use them for professional and educational purposes. Therefore, going for a webcam with a separate mic is recommended to ensure listeners hear your voice.

Another reason to use a webcam without a built-in mic is that the manufacturers don’t have to focus on the mic and would focus on other things. Moreover, most webcams without a microphone provide better image quality and resolution. Their prices are more affordable than those webcams with built-in microphones. Besides, they provide excellent image and video quality. Let’s get familiar with when to use a webcam without a mic.

When to use a webcam without a mic?

A webcam without a mic can also offer quality that is exceptional. It offers options for complex audio projects like podcasting, live streaming classes, music recording, and presentations. Usually, an external USB microphone is a smart investment in such cases.

Webcams are designed to record videos and capture still shots for business professionals, streamers, and casual users. The inclusion of a sub-par microphone may not be effective if you demand extremely high-quality audio.

You can use a webcam with a microphone for your computer use and average communication.

Factors to consider before buying a webcam without a microphone:

1) Video resolution:

Your webcam without a microphone should have a minimum HD resolution whether you stream or record videos. 720p resolution can work in some cases. But choosing the one with at least 1080p or higher resolution is better. Those with 1080p resolution provide excellent smoothness and clarity.

2) Frame rate:

It denotes the number of images your camera can capture per second. Make sure to choose a webcam with a microphone whose frame rate is at least 30 fps; otherwise, the video recording will have a shaky effect.

3) Optical zoom:

Optical zoom capability is beneficial if you use your webcam without a microphone for gaming, webinars, or professional video calls. If you wish to obtain the best performance for conference calls, choose a webcam with at least 4x visual zoom capability. The mentioned zoom capability is essential when dealing with auditoriums and large conference halls.

4) Auto image adjustments:

A webcam without a microphone that supports auto image adjustments lets you quickly adjust images while conducting a business meeting or pursuing online learning. Certain webcams without microphones have a special lens that avoids image distortion and enhances image quality in low-light conditions. The lens decides the amount of light that reaches the camera sensor.

The top-notch quality lenses guarantee superior image quality and automatic image adjustment. To benefit from automatic image adjustments, ensure your webcam has color, white balance, and low-light correction abilities.

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:

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.
