Sony Semiconductor Solutions has announced the upcoming launch of its new LYTIA 720 image sensor, designed for primary smartphone cameras. This sensor boasts a 1/1.56-inch image size and approximately 50 effective megapixels, featuring a stacked structure. Mass production and shipping are anticipated to begin in early November.
The LYTIA 720 integrates Sony’s UHCG circuit technology, which efficiently converts electric charge into voltage. This advancement significantly reduces random noise in low-light conditions, reportedly halving it compared to previous sensors of the same specification, such as the LYTIA 700.
A key highlight of the LYTIA 720 is its capability to support 4K 60fps HDR video recording with full-pixel autofocus. This marks a first for the LYTIA series in a 1/1.56-inch sensor with a 1μm pixel pitch. This impressive feat is achieved while simultaneously reducing sensor power consumption through its AD conversion circuit.
Furthermore, the sensor supports Hybrid Frame-HDR technology. This innovative feature works in conjunction with the rear application processor to synthesize image data. It combines DCG-HDR image data, captured with a single exposure across low to mid-brightness ranges, with image data from a short exposure that captures the high-brightness areas. When combined with the UHCG technology, this results in an impressive dynamic range of 100dB, allowing for more detailed and vibrant video footage in challenging lighting scenarios.
Sony’s continuous innovation in image sensor technology, exemplified by the LYTIA 720, aims to push the boundaries of mobile photography and videography, particularly in demanding low-light and high-contrast situations. The sensor’s focus on noise reduction and enhanced HDR capabilities suggests a strong emphasis on delivering professional-grade video performance directly from smartphones.
