ATSUGI, Japan, June 24, 2026 /PRNewswire/ -- Sony Semiconductor Solutions Corporation (Sony) today announced the upcoming release of the LYTIA 610, a 1/2-type approximately 64-effective megapixel CMOS image sensor with the RB2×2 On Chip Lens (OCL) pixel structure. This is the industry's first product with this pixel structure to be mass produced.
By combining the RB2×2 OCL pixel structure with dedicated array conversion processing (remosaicing) optimized for this structure, the new product achieves both improved resolution and excellent autofocusing (AF) performance at the same time. It offers more than 20% improvement in spatial resolution compared to Sony's conventional product with the same pixel size, allowing telephoto cameras to capture subjects with fine detail.
The improved readout speed also enables 4K 120 fps video recording for the first time on Sony's 1/2-type sensor. This reduces the performance gap with the large sensors used on main cameras and suppresses variations in image quality across multi-lens camera systems, enabling a more uniform shooting experience.

*2 Spatial resolution: An indicator used for evaluating image definition. This figure quantifies the level of detail at which thin, alternate black and white lines can be clearly distinguished. A higher value indicates a finer depiction of detail in the subject.
*3 Compared with the LYTIA 601 mobile CMOS image sensor with a 2×2 OCL construction and pixel size of 0.7 µm.
*4 Based on the image sensor effective pixel specification method.
The RB2×2 OCL pixel structure features an optimal arrangement of a 1×1 OCL structure for ensuring high resolution and a 2×2 OCL structure for enhancing AF performance on a single sensor.
Furthermore, a new dedicated remosaicing (array conversion) processing algorithm was developed to further enhance the imaging performance of this unique pixel array. The optimized pixel structure and signal processing together deliver more than 20% improvement in spatial resolution compared to the conventional product of the same pixel size, while maintaining superb AF performance.
The logic circuits on this product employ fine processing for low energy consumption. Additionally, the AD converter (analog-to-digital conversion circuit) has been optimized through increased parallelization to achieve high-speed data readout that is double that of the conventional 1/2-type sensor.
The improved readout speed enables 4K 120 fps video recording for the first time on Sony's sensor of the same size, which had been difficult to achieve with previous designs.
