Abstract

We propose a new concept image sensor suitable for viewing and sensing applications. This is a report of a CMOS image sensor with Ta -Kuchi pixel architecture consisting of a 1.5μm pixel with four shared pixel structures and a 3.0μm pixel with in -pixel -capacitor. They are arranged in a staggered pitch. This architecture achieves both a High Dynamic Range (HDR) of 106dB and LED Flicker Mitigation (LFM) as well as Motion Artifact Free, and Motion blur less. As a result, moving subjects can be accurately recognized and detected with good color reproducibility in any lighting environment. This allows a single sensor to deliver the performance required for viewing and sensing applications.
