Focus on the Future: A Generational Leap in Autofocus
Perhaps the biggest technological gap is in how these sensors achieve focus. It's a classic case of an older, capable system versus a modern, revolutionary one.
OV64B: ML-PDAF
Uses a grid of special microlenses over 2x2 pixel groups to detect focus. It's effective, especially in low light, but only uses a fraction of the sensor's pixels for the job.
Focus is detected at specific points (blue).
LYT-600: All-Pixel AF
A true game-changer. Every single pixel on the sensor can be used for both imaging and phase detection. This results in dramatically faster, more accurate focus across the entire frame.
The entire sensor contributes to focus.
The Magic of Pixel Binning
Both sensors combine four small pixels into one large 'super pixel' to capture more light in dark conditions. Here's how they stack up.

LYT-600: 1.6µm Super Pixel

Under the Hood: Sensor Architecture
Both sensors use a "stacked" design, which separates the light-sensitive pixels from the processing logic. This allows for more complex features and a smaller overall footprint. However, their underlying pixel technologies differ.
OV64B: PureCel®Plus-S
- ✓ Deep Trench Isolation: Physically separates pixels to prevent color crosstalk and improve fidelity.
- ✓ Buried Color Filter: Improves light collection from sharp angles, crucial for thin smartphone lenses.
LYT-600: Sony Stacked CMOS
- ✓ Pioneering Tech: Sony pioneered this stacked structure, perfecting the separation of pixel and circuit layers.
- ✓ LYTIA Philosophy: Focuses on user experience, integrating hardware and software for tangible benefits like better HDR and faster focus.
HDR Tech: Capturing Light & Shadow
High Dynamic Range (HDR) is essential for balancing bright skies and dark shadows. The sensors use different on-chip methods to achieve this effect.
OV64B: Staggered HDR
The sensor captures multiple exposures (e.g., short, medium, long) in sequence, one after the other. The ISP then merges them. This can sometimes lead to motion artifacts if the subject moves between frames.
Short
Medium
Long
LYT-600: LBMF (Less Blanking)
A more modern technique where the time between multiple exposures is dramatically reduced. This minimizes motion blur and artifacts, resulting in cleaner, more stable HDR video and photos of moving subjects.

Real-World Showdown: Case Studies
A sensor's specs are just one part of the story. Here’s how they perform inside actual phones, where software and processing power play a huge role.
The Telephoto Specialist: OV64B in the OnePlus 12
☀️ Daylight Zoom
3x optical shots are sharp and detailed. 6x in-sensor zoom is very usable, leveraging the high 64MP resolution.
🔬 Close-Focusing
A surprise strength. The telephoto lens can focus on close subjects, creating excellent macro-style shots.
🌙 Low Light Telephoto
Images are nice with good detail, though dynamic range can be limited without post-processing.
The Mid-Range Mainstay: LYT-600 in the Realme 12+ & Oppo Reno 11
🎨 Color Science
A common issue in mid-range phones. Colors are often heavily saturated and unnatural, with narrow dynamic range.
👤 Portrait Performance
A highlight for the sensor, especially with Oppo's tuning. It delivers good subject separation and natural skin tones.
🌃 Low Light & Video
Performance is decent but not spectacular. Images can show aggressive sharpening, and video stabilization often requires a drop to 1080p.
It's Not Just the Sensor: The Ecosystem Matters
A sensor is only as good as the system around it. A powerful Image Signal Processor (ISP) and expert software tuning can make an older sensor shine, while a weaker ecosystem can hold a new sensor back.
Flagship Ecosystem (e.g., OnePlus 12)
OV64B
(Snapdragon 8 Gen 3)
(Hasselblad)
Excellent Zoom
Mid-Range Ecosystem (e.g., Realme 12+)
LYT-600
(Dimensity 7050)
(Realme Algorithm)
Good but Mixed
Beyond Stills: A Deep Dive into Video
On paper, the OV64B's 8K capability seems like a clear win. But as with photos, the real-world performance tells a more nuanced story shaped by software and processing power.
OV64B: The Resolution King
- ✓ 8K @ 30fps: A flagship-tier spec that offers incredible detail, if your device can handle it.
- ✓ Rich Slow-Mo: More options with 1080p @ 240fps and 720p @ 480fps.
- ~ Real-World Use: As a telephoto sensor, footage can be jittery and is often secondary to the main camera's video.
LYT-600: The Modern Standard
- ✓ 4K @ 60fps: The sweet spot for smooth, high-quality video for most users.
- ✗ Tuning is Critical: Mid-range implementations often suffer from overly saturated colors and poor dynamic range.
- ✗ EIS Trade-offs: On some devices, enabling stabilization forces a drop to 1080p, a major compromise.
The Market Journey: From Workhorse to Successor
April 2020
OV64B Launches
Introduced as a high-res sensor for main or secondary cameras, it later found its true calling as a cost-effective telephoto "workhorse" in flagship phones.
June 2023
LYT-600 Debuts
Launched under the new LYTIA brand, it's strategically positioned as the modern, versatile successor for the mainstream and mid-range markets.
The Final Verdict
🏆 Winner on Tech: Sony LYT-600
From a pure technology standpoint, the LYT-600 is the more modern and capable sensor. Its larger pixels and superior 'All-pixel AF' give it a higher ceiling for overall image quality, especially for a primary camera.
🎯 Winner in Practice: It Depends!
The OV64B, despite its age, proves that context is king. In a flagship phone with a powerful processor, its high resolution makes it an exceptional telephoto specialist, often outperforming the LYT-600 in its specific role.
