ATSUGI, Japan — Sony Semiconductor Solutions Corporation announced the upcoming release of the LYTIA 901, a 1/1.12-type mobile image sensor with approximately 200 effective megapixels. The sensor is designed to deliver high-definition imaging and maintain image quality during zooming of up to 4x on monocular smartphone cameras, according to the company.
The LYTIA 901 uses a 0.7 μm pixel pitch and a Quad-Quad Bayer Coding (QQBC) array, grouping 16 adjacent pixels under the same color filter. During standard shooting, these clusters function as single units to enhance sensitivity in low-light environments. When zooming, remosaicing technology restores the clustered pixels to a standard array to produce high-resolution images.
Sony has integrated a new AI learning-based remosaicing function directly into the sensor. The company states that this approach improves reproduction of fine details, including patterns and lettering, and supports high-speed processing for up to 30 frames-per-second video recording at 4K resolution with up to 4x zoom.
The sensor also incorporates multiple high dynamic range technologies. Dual Conversion Gain-HDR combines data captured at different gain levels within a single frame, while Fine12bit ADC increases quantization depth from 10 to 12 bits. Sony reports that these features support consistent tonal expression across the full zoom range.
The LYTIA 901 additionally includes Hybrid Frame-HDR, which blends short-exposure frames with DCG data during post-processing. According to the company, this method achieves dynamic range performance exceeding 100 dB, helping to reduce highlight blowout and preserve detail in dark areas.
Release timing and availability were not included in the announcement.
