Sony introduces 200-megapixel LYTIA 901 sensor, features AI processing, 4x in-sensor zoom

Sony has launched the Sony LYT-901 mobile camera sensor. Designed for upcoming flagship smartphones, this sensor is Sony’s first 200-megapixel image sensor designed for phones. The Sony LYT-901 features a large 1/1.12-inch imaging surface, competing directly with Samsung’s 200-megapixel sensor platform. Here, we explain this new camera technology in detail.

Sony LYT-901 Specifications

The Sony LYT-901 features a large 1/1.12-inch imaging surface, combined with 0.7μm pixels and a 200-megapixel output. This is the brand’s first sensor with this resolution designed for mobile phones. An earlier codename associated with this hardware was IMX09E, before Sony added its LYTIA series labeling. Sony expands the base pixel grid using a quad-quad Bayer mosaic. This translates to a 2×2 Bayer pattern via a hardware remosaic path.

The company incorporated AI logic into the sensor’s internal rebayer circuit, reducing translation penalties and making it easier for the phone processor to manage dense pixel data. A 12-bit analog-to-digital pipeline supports a fine 12-bit ADC, providing additional latitude in gradation. This helps maintain clean, low-noise full-resolution reads.

For HDR, Sony built on dual conversion gain HDR and combined it with a hybrid frame-HDR design. This samples a microsecond-class very small additional frame. It controls highlight clipping while avoiding obvious ghosting in fast scenes. The combined dynamic range exceeds 100dB, which is 17 photographic stops. In zoom mode, the sensor manages 2x hardware zoom for photos and 4x in-sensor zoom for still photos and video. At 4x zoom, phones can tap into the stream as a virtual telephoto view without any additional optical lens step.

This is the only current sensor that can capture 4x hardware zoom and 4K video at 30fps. 120fps 4K capture is also available in a 4x binning configuration. The pixel binning profiles include 50 megapixels (2×2) and 12.5 megapixels (4×4), which give a more composed look to night capture and high-zoom crops. It is tuned for stage shows and arena moments. It can be used for concert photography.
