Camera system with motion-dependent resolution

摘要

A camera system (100) includes a first camera (104) having a low-resolution image sensor (500) with a plurality of image sensing regions (604). The camera system includes a plurality of high-resolution cameras (106A-106O). Each of the high-resolution cameras is associated with a set of the plurality of image sensing regions. The first camera is configured to detect motion based on sensed images, identify a set of the image sensing regions based on the motion, and power on the high-resolution camera associated with the identified set of image sensing regions.
