Abstract:
1. A method for controlling a shutter for use in an image sensor, the method comprising: sequentially opening electronic shutters for every imaging line; opening a mechanical shutter after all of the electronic shutters of every imaging line are opened and after a stabilizing delay time occurs to allow pixels to stabilize after the electronic shutters are opened; closing the mechanical shutter after a predetermined exposure time passes; and sequentially carrying out reading line image data of every imaging line; wherein an integration time of the electronic shutters is the sum of (1) a turn-on delay time extending from an opening of an electronic shutter at a first imaging line until an opening of an electronic shutter at a last imaging line, (2) the stabilizing delay time, and (3) the predetermined exposure time of the mechanical shutter; wherein the turn-on delay time is a sum of intervals between openings of successive electronic shutters during the sequential opening of the electronic shutters of each of the imaging lines; and wherein a rate of said sequentially carrying out reading line image data is identical to a rate of said sequentially opening electronic shutters.
