Patent ID: 8803990

Claim:
A method for capturing image data for a high-dynamic-range image using multiple image sensors in an electronic device each of which receives image light through a respective lens in a lens array in the electronic device, the method comprising: with a first of the image sensors, capturing image data using a first exposure time; with a second of the image sensors, capturing image data using a second exposure time that is longer than the first exposure time; and in synchronization, reading out data from rows of image pixels in the first and second image sensors using control circuitry in the electronic device, wherein the first and second image sensors use an electronic rolling shutter scheme to capture images; and asserting a first reset signal for the first image sensor at a first time, asserting a second reset signal for the second image sensor at a second time subsequent to the first time, wherein reading out the data from the first and second image sensors comprises asserting a read signal for a given row in the first image sensor at a third time and simultaneously asserting a read signal for the given row in the second image sensor at the third time, wherein the third time is after the first and second times.
