Sony Semiconductor Solutions Corporation today announced the upcoming release of the LYTIA 901, a 1/1.12-type stacked CMOS mobile image sensor featuring approximately 200 effective megapixels. The sensor introduces a redesigned pixel architecture, improved low-light capture, and AI-based image processing embedded inside the sensor to preserve detail during zoom shooting and video recording.
LYTIA 901 CMOS image sensor
The LYTIA 901 uses a 1/1.12-type (14.287 mm diagonal) format with a 0.7 μm pixel pitch to achieve its approximately 200-effective-megapixel resolution. It also marks the start of Sony’s new unified naming format in which all upcoming models will follow the structure “LYTIA (product number).”
Key features
Quad-Quad Bayer Coding (QQBC) for high resolution and sensitivity
The QQBC arrangement clusters 16 same-color pixels to maximize sensitivity for regular shooting, especially in dim environments. For zoom capture, remosaicing restores full pixel layout to maintain high resolution.
- 16 (4×4) same-color pixels processed as one unit during standard shooting
- High-resolution reconstruction for up to 4× zoom
- Updated pixel structure and color filter enhance saturation signal and dynamic range
AI learning-based remosaicing inside the sensor
Sony has developed a new AI learning-based remosaicing technique for the QQBC structure and integrated the processing hardware directly into the sensor. This enables reproduction of high-frequency visual elements while supporting real-time zoom recording.
- Resolves fine textures, small lettering, and high-frequency patterns
- Enables 4K video recording at up to 30 fps with up to 4× zoom
- On-sensor processing reduces computation latency and improves efficiency
HDR technologies for tonal accuracy and wide dynamic range
The LYTIA 901 combines DCG-HDR, Fine12-bit ADC, and HF-HDR to maintain tonal precision and detail across bright and dark regions. In 16-pixel additive mode, HDR processing achieves an effective dynamic range of over 100 dB.
- DCG-HDR merges signal data captured at different gain levels in a single frame
- Fine12-bit ADC increases bit depth from conventional 10-bit to 12-bit
- HF-HDR composites short-exposure frames with DCG data to expand dynamic range

Availability
Sony states that mass-production shipments of the LYTIA 901 will begin in November 2025. The sensor is set to appear in upcoming flagship Android smartphones, with real-world performance expected once consumer products launch.
Reports indicate that the OPPO Find X9 Ultra and vivo X300 Ultra are likely to be among the first devices to adopt it in Q1 2026.
