Abstract
An image sensor includes an active pixel array including a number of pixels and image sensor control circuitry configured to perform a read operation only on a subset of the pixels of the active pixel array such that pixels not in the subset remain inactive. By reading out only the subset of pixels in the active pixel array and keeping the remaining pixels inactive, the temperature of the active pixel array may be reduced compared to a conventional read out process, thereby reducing thermal noise in the resulting pixel data.
