A 1-inch Optical Format, 10 8Mpixel, 80fps CMOS Image Sensor with Pipelined-Pixel Readout

Abstract

A 1-inch optical format, 80fps, 10.8M-pixel CMOS image sensor for both high-end video and still camera applications is developed. The 80fps readout speed was chosen because of a minimum requirement for a strobe sync speed of 1/60s for mechanical shutter-less still camera use and also for reducing rolling shutter distortion on moving objects. In order to satisfy this frame rate requirement with a minimum increase in analog power consumption, a new pipelined pixel to ADC scheme was introduced and successfully demonstrated with noise performance good enough for high end camera applications.
