Sony has introduced the LYTIA 720, a 50-megapixel mobile image sensor featuring enhanced low-light performance, a 100dB dynamic range and support for 4K HDR video recording at 60 frames per second.

Sony has announced the LYTIA 720, a new 50-megapixel stacked CMOS image sensor designed for mobile devices, with a focus on improving image quality in challenging lighting conditions.

The sensor measures 1/1.56 inches and features a pixel size of 1.0 micrometre. It incorporates Sony’s proprietary Ultra High Conversion Gain (UHCG) circuit technology, which the company says can reduce random noise by up to 50% compared with the LYTIA 700.

Enhanced HDR and Low-Light Performance

The LYTIA 720 combines UHCG technology with Hybrid Frame-HDR (HF-HDR) to deliver a claimed dynamic range of 100dB. This is designed to preserve more detail in both bright and dark areas when photographing high-contrast scenes.

According to Sony, the technologies enable clearer still images with improved shadow detail and fewer blown-out highlights. The company also says the resulting images can more closely resemble what the human eye sees.

The sensor supports 4K video recording at 60 frames per second with HDR, using single-frame HDR technology. This could help mobile devices capture video with greater detail across varying lighting conditions.

The combination of noise reduction and HDR capabilities is intended to improve image quality without relying solely on computational processing.

Mass Production to Begin Soon

Sony says shipments of the LYTIA 720 for mass production will begin early next month. The announcement does not identify which smartphone manufacturers or devices will use the new sensor.

Its specifications suggest a focus on balancing low-light performance, high dynamic range and video capabilities for future mobile cameras. However, actual results will depend on how manufacturers integrate the sensor into their devices and combine it with their camera software.
