en.Wedoany.com Reported - Sony Semiconductor Solutions has launched the LYTIA L910 mobile image sensor, which achieves a 100dB dynamic range using LOFIC structure and TCG-HDR technology, with mass production shipments expected this summer.

The LYTIA L910 features a LOFIC structure capable of accumulating overflow charges from photodiodes, increasing the saturation charge level compared to its predecessor, the LYTIA 828. The sensor also adopts Triple Conversion Gain-HDR (TCG-HDR) technology, which reads out charges obtained from a single exposure at three conversion efficiencies, thereby suppressing overexposure in bright areas and reducing noise from dark to mid-tone regions.

By utilizing UHCG (Ultra High Conversion Gain) circuit technology to enhance the charge-to-voltage conversion efficiency, the LYTIA L910 reduces random noise generation by approximately 30% compared to the LYTIA 828, improving image quality under low-light conditions. These technologies enable a 100dB dynamic range with a single exposure, suppressing grainy noise in low-light environments while achieving smooth gradation in scenes with high contrast.

The sensor eliminates the need for multiple exposures, reducing motion blur in moving objects. By extending exposure time, it also improves the signal-to-noise ratio of imaging signals and suppresses flicker from lighting. The unique circuit design and advanced process shorten the analog-to-digital conversion processing time, reducing sensor power consumption. While minimizing battery drain, the sensor can capture 4K video at 60fps and supports real-time HDR preview on smartphones.
