Atsugi, Japan — Sony Semiconductor Solutions Corporation (Sony) today announced the upcoming release of the 1/1.12-type large-format LYTIA 901 mobile image sensor with a high resolution of approximately 200-effective megapixels.*1 This product uses a pixel array format that delivers both high resolution and high sensitivity, further incorporates an image processing circuit utilizing AI technology within the sensor. It achieves high-definition image quality even with high-powered zooming of up to 4x on monocular cameras and offers new experiential value when shooting on mobile cameras.
*1 Based on the image sensor effective pixel specification method.

Main Features
■Approximately 200-effective megapixels and Quad-Quad Bayer Coding (QQBC) array deliver both high resolution and high sensitivity
-
The new sensor uses a pixel pitch of 0.7 μm for an approximately 200-effective megapixel resolution on a 1/1.12 large-format sensor. Advances in pixel structure and color filter design increase the saturation signal level, contributing to improved dynamic range.
-
To leverage the high resolution of approximately 200-effective megapixels, the new product employs a Quad-Quad Bayer Coding (QQBC) array in which 16 (4×4) adjacent pixels are clustered with filters of the same color. During normal shooting, the signals of the 16 clustered pixels are processed as a single pixel unit, allowing the camera to maintain high sensitivity even at night and in dim indoor shooting conditions. On the other hand, during zoom shooting, a form of array conversion processing known as remosaicing reverts the clustered pixels to a normal pixel array, to deliver high-resolution imaging.
■Equipped with an AI learning-based remosaicing function for high quality imaging while zooming
Array conversion processing (remosaicing), which reverts the QQBC array to a normal pixel array, requires extremely advanced calculation processes. For this product, Sony has developed a new AI learning-based remosaicing for the QQBC array and mounted the processing circuit inside the sensor, for another Sony industry-first.*2 This new technology makes it possible to process high-frequency component signals, which are generally difficult to reproduce, offering superior reproduction of details such as fine patterns and letters. Furthermore,incorporating AI learning-based remosaicing directly in the sensor enables high-speed processing and up to 30 fps high- quality video capture when shooting with up to 4x zoom in 4K resolution.
*2 Among CMOS image sensors for mobile applications. According to Sony research (as of November 27, 2025).
■High dynamic range and rich tonal expression enabled by various HDR technologies
-
DCG-HDR and Fine12bit ADC technologies deliver high dynamic range and tonal expressions across the entire zoom range up to 4x
In addition to Dual Conversion Gain‐HDR (DCG-HDR) technology, which composites data read at different gain settings in a single frame, the new sensor is equipped with Fine12bit ADC (AD converter) technology that improves the quantization bit depth from the conventional 10 bits to 12. These features deliver a high dynamic range and rich tonal expression across the entire zoom range up to 4x. -
HF-HDR technology delivers over 100 dB*3 high dynamic range performance
Hybrid Frame-HDR (HF-HDR) is an HDR technology that composites frames captured in short exposures with DCG data on a post-processing application processor. HF-HDR significantly improves the dynamic range compared to conventional HDR technology, delivering performance of over 100 dB.*3 This significantly suppresses highlight blowout in bright areas, as well as blackout in dark areas, delivering images that more closely resemble what the human eye actually sees.*3 Effective in 16-pixel additive mode.
To enhance recognition of the LYTIA product brand, all future products launched under this brand, beginning with “LYTIA 901” will follow the unified naming format “LYTIA (product number).”
