Sony Semiconductor Solutions has introduced the LYTIA 610, a new 64-megapixel CMOS image sensor featuring an industry-first RB2×2 On-Chip Lens (OCL) pixel structure designed to improve image quality, autofocus performance and high-speed video capture in smartphone cameras.
Sony Semiconductor Solutions has announced the upcoming release of the LYTIA 610, a 1/2-type, approximately 64-effective megapixel stacked CMOS image sensor for mobile devices. The company says it is the first mass-produced CMOS image sensor to feature the RB2×2 On-Chip Lens (OCL) pixel structure, a new design intended to enhance both image resolution and autofocus performance.
The sensor combines the new pixel structure with a dedicated remosaicing algorithm, enabling more than 20% higher spatial resolution compared with Sony’s conventional sensor using the same 0.7 μm pixel size. According to the company, the technology is particularly suited for smartphone telephoto cameras, allowing them to capture finer details while maintaining accurate autofocus.
Sony explained that the RB2×2 OCL architecture integrates two different lens configurations within a Quad Bayer array. A 1×1 OCL structure is used for green pixels to maximise image sharpness, while a 2×2 OCL structure supports phase-detection autofocus. This combination is designed to improve overall imaging performance without compromising focusing speed.
The LYTIA 610 also introduces faster data readout capabilities. Sony said the sensor is its first 1/2-type mobile image sensor to support 4K video recording at 120 frames per second, helping reduce the performance gap between telephoto cameras and larger primary camera sensors commonly found in smartphones. The higher readout speed is expected to deliver more consistent image quality across multi-camera systems.
Mass production shipments of the LYTIA 610 are scheduled to begin at the end of June 2026. Sony expects the new sensor to support the next generation of premium smartphone cameras by improving photography, autofocus accuracy and high-frame-rate video recording within compact camera modules.
