Claim:
1. A method of operating a camera device to scan a portion of a scene area of interest, the method comprising: controlling a plurality of image sensors to scan the scene area of interest from a first edge of said scene area of interest to a second edge of said scene area of interest, said first and second edges of said scene area of interest being parallel, said scanning including controlling image capture according to a scan position which progresses from said first edge to said second edge of the scene area of interest, said controlling including operating a first image sensor in said plurality of image sensors in rolling shutter mode to read out a row of pixel values corresponding to a current scan position when said first image sensor has a row of pixel values corresponding to said current scan position, said current scan position changing over time, said controlling further including operating a second image sensor in said plurality of image sensors in rolling shutter mode to read out a row of pixel values corresponding to the current scan position when said second image sensor has a row of pixel values corresponding to said current scan position, said first and second image sensors capturing images of different portions of said scene area of interest; wherein said first image sensor corresponds to an optical chain having a first focal length; wherein said second image sensor corresponds to an optical chain having a second focal length; and wherein said controlling includes controlling the rate at which pixel rows are read out of the first and second image sensors as a function of the focal length of the individual optical chains to which the first and second image sensors correspond.
