LYTIA 720 CMOS image sensor

Main Features
■Proprietary UHCG circuit technology delivers industry-leading^*2 low-light performance
Ultra High Conversion Gain (UHCG) circuit technology that achieves high charge-to-voltage conversion efficiency suppresses image grain caused by noise in dark environments. It also reduces random noise by approximately 50% compared to a conventional product,^*3 delivering the industry-leading^*2 low-light performance and high-quality imaging with reduced noise in dark scenes.

■Optimized AD conversion circuits enable 4K 60 fps HDR video recording with all-pixel autofocus
The optimized circuit design reduces the time required for AD conversion, enabling 4K 60 fps HDR video recording with all-pixel autofocus while lowering sensor power consumption. This is the first 1/1.56-type LYTIA product with a 1.0 μm pixel size to support this feature. Additionally, using single-frame HDR technology for 4K 60 fps HDR video recording suppresses motion artifacts while maintaining sufficient exposure time for low-noise imaging.

■Hybrid Frame-HDR technology delivers a 100 dB dynamic range
Hybrid Frame-HDR (HF-HDR) is an HDR technology that combines Dual Conversion Gain-HDR (DCG-HDR) with frames recorded at short exposures. DCG-HDR imaging data, which covers low- to medium-brightness ranges with a single exposure, is merged with high-brightness range imaging data that was obtained through a short exposure in post-processing thereby expanding the dynamic range. HF-HDR technology, combined with UHCG circuit technology, delivers a dynamic range of 100 dB. This enables imaging that more closely resembles what the human eye perceives, with reduced loss of detail in shadows and highlight blowouts even in high-contrast scenes.
