Image sensors and image processing devices that support rolling and global shutter modes of operation

Abstract

An image sensor pixel includes: first and second sub-pixels, which are electrically coupled to first and second floating diffusion nodes of the pixel, respectively; a first rolling shutter operation circuit configured to read out photocharges that are collected in the first floating diffusion node during a rolling shutter mode of operation; a second rolling shutter operation circuit configured to read out photocharges that are collected in the second floating diffusion node during the rolling shutter mode of operation; a global select switch circuit electrically coupled to the first and second rolling shutter operation circuits; and a global shutter operation circuit electrically coupled to the global select switch circuit. The global shutter operation circuit is configured to read out photocharges that are: (i) collected in the first and second floating diffusion nodes, and (ii) pass through the global select switch circuit during a global shutter mode of operation.
