Abstract
A method of operating an image sensor includes determining a duration of an integration time for an image frame; operating an array of pixels to capture the image frame; receiving a decision to truncate the image frame; truncating the image frame before satisfying the duration of the integration time; and reading out a set of pixel values for the array of pixels. Each pixel in the array of pixels is exposed for a truncated integration time. The truncated integration time has a truncated duration shorter than the determined duration.
