Hybrid CIS / EVS image sensor providing high EVS resolution

Abstract

Hybrid CIS / EVS image sensors are disclosed herein. In one embodiment, a pixel arrangement includes a plurality of pixels and a color filter array. Each of the plurality of pixels can include a photosensor, a floating diffusion, a transfer transistor, and an EVS transistor configured to selectively couple the photosensor to an event driven circuit corresponding to the pixel. The color filter array can include a plurality of color filters arranged in a mosaic pattern over photosensors of the plurality of pixels such that the photosensor of a first pixel of the plurality of pixels corresponds to a first color and the photosensor of a second pixel of the plurality of pixels corresponds to a second color different from the first color. The event driven circuits corresponding to the plurality of pixels can be (a) different from one another and (b) selectively coupled to one another via a common node.
