METHODS AND APPARATUS FOR SYNCRONIZING READOUT OF MULTIPLE IMAGE SENSORS

摘要

Methods and apparatus for reading out pixel values from sensors in a synchronized manner are described. Readout of rows of pixel values from different sensors are controlled so that pixel values of different sensors corresponding to the same portion of a scene are read out in a way that the same portions of a scene are captured at the same or nearly the same time by different sensors. In one embodiment a first sensor which captures a large scene area alternates between reading out rows of pixel values from a top portion and a bottom portion of the first sensor while sensors corresponding to smaller areas of the scene read out rows of pixel values in a consecutive manner. Sensors may read out rows of pixel values at the same rate despite corresponding to optical chains with different focal lengths. The image captured by the first sensor facilitates image combining.
