Sony has officially entered the 200-megapixel race. On November 27, 2025, Sony Semiconductor Solutions unveiled the LYTIA 901 — originally introduced as the LYT-901 — a 1/1.12-type stacked CMOS sensor with roughly 200 effective megapixels. The headline isn’t just the resolution. The LYT-901 is the first mobile image sensor to put an AI-based remosaicing circuit directly inside the silicon, and it could quietly reshape how flagship phones handle zoom, low light, and video.

Sony’s first 200MP sensor, on a large 1/1.12-inch format

The LYT-901 packs about 200 effective megapixels into a 1/1.12-type sensor with a 14.287 mm diagonal and a pixel pitch of just 0.7 µm. That large format — bigger than the typical 1/1.3-inch and 1/1.28-inch flagships — is the biggest playground Sony has given a mobile sensor in this class. According to leaker reports cited by TechRadar, it is currently the world’s largest 200MP smartphone sensor, putting it squarely against Samsung’s ISOCELL HP-series 200MP chips that have dominated the segment since 2023.

Sony pairs the resolution with a Quad-Quad Bayer Coding (QQBC) color filter. In this layout, 16 adjacent pixels in a 4×4 block share the same color filter. During normal shooting, the sensor merges those 16 pixels into a single output pixel — roughly 12.5 megapixels — so each effective pixel gathers far more light. That’s the trick behind the improved sensitivity in dim indoor and night scenes.

On-sensor AI remosaicing: the industry-first feature

When you zoom in, though, the sensor has to undo that clustering. Converting a QQBC array back into a normal Bayer pattern — a process called remosaicing — is extremely demanding math, because it must reconstruct high-frequency detail such as fine patterns and small text. Sony’s answer is an AI learning-based remosaicing circuit mounted inside the sensor itself, which the company calls an industry first among mobile CMOS sensors.

Doing this on-chip matters for two reasons. First, it reproduces fine detail more faithfully than conventional remosaicing. Second, it removes a processing bottleneck, enabling high-speed output. Sony says the sensor can capture 4K video at up to 30 fps while shooting with up to 4x in-sensor zoom, keeping high definition across the zoom range without needing a separate telephoto lens.

HDR and speed: DCG-HDR, Fine12bit ADC and HF-HDR

Sony loaded the LYT-901 with a full HDR toolkit. DCG-HDR (Dual Conversion Gain-HDR) composites data read at two different gain settings within a single frame, while Fine12bit ADC lifts quantization bit depth from the conventional 10 bits to 12 bits for richer tonal gradation. Together they keep dynamic range high across the entire 4x zoom range.

For extreme contrast, HF-HDR (Hybrid Frame-HDR) blends short-exposure frames with DCG data on the application processor, pushing dynamic range past 100 dB in the 16-pixel additive mode. Sony claims this visibly suppresses blown highlights in bright areas and crushed blacks in shadows, producing images closer to what the human eye sees.

Speed is equally strong: the sensor supports 8K video at 30 fps and 4K at 120 fps, plus burst capture of 60 fps at 12.5MP, 30 fps at 50MP, and 10 fps at the full 200MP resolution.

Which phones will get the LYT-901?

Nothing is official yet, but the rumor mill points to the usual flagship suspects. Leaker sondesix reports the sensor will land in the vivo X300 Ultra and Oppo Find X9 Ultra, while UniverseIce adds that Xiaomi and Honor flagships could adopt it too. The vivo X300 Ultra has since been confirmed to use a 200MP Sony LYT-901 main camera paired with a 35mm-equivalent lens and ZEISS optics. Mass production began in November 2025, so expect the first handsets in 2026.

Conclusion

The LYT-901 is Sony’s long-awaited answer in the 200MP war, but its real story is the on-sensor AI. By moving remosaicing onto the chip, Sony is betting that computational photography will increasingly happen before the image ever leaves the sensor. If that bet pays off, “built-in AI” could become the next spec that flagship buyers actually notice.

FAQ

What makes the Sony LYT-901 different from other 200MP sensors?

It’s the first mobile sensor with an AI learning-based remosaicing circuit built into the chip, and it’s the largest 200MP smartphone sensor at 1/1.12 inches.

Which phones will use the Sony LYT-901?

The vivo X300 Ultra is confirmed to use a 200MP LYT-901 main camera. The Oppo Find X9 Ultra is widely expected to follow, with Xiaomi and Honor flagships also rumored.

Can the Sony LYT-901 record 8K video?

Yes — the sensor supports 8K at 30 fps and 4K at 120 fps, along with up to 30 fps 4K capture at 4x in-sensor zoom.
