Multiple-row concurrent readout scheme for high-speed CMOS image sensor with backside illumination

摘要

A system, method and apparatus implementing a multiple-row concurrent readout scheme for high-speed CMOS image sensor with backside illumination are described herein. In one embodiment, the method of operating an image sensor starts acquiring image data within a color pixel array and the image data from a first set of multiple rows in the color pixel array is then concurrently readout. Concurrently reading out the image data from the first set of multiple rows includes concurrently selecting a first portion of the image data from the first set by first readout circuitry and a second portion of the image data from the first set by second readout circuitry. The first and second portions of the image data from the first set are different and the first and second readout circuitries are also different. Other embodiments are also described.
