A method of operating a camera device to scan a scene area of interest, the method comprising: controlling a plurality of image sensors (1217"', 1247, 1247', 1247", 1247"', 1247"") 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 (1247, 1217'") 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 (1217"', 1247) 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 (1204, 1212) having a first focal length; wherein said second image sensor corresponds to an optical chain (1212, 1204) having a second focal length, said second focal length being different from said first 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. controlling a plurality of image sensors (1217"', 1247, 1247', 1247", 1247"', 1247"") 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 (1247, 1217'") 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 (1217"', 1247) 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 (1204, 1212) having a first focal length; wherein said second image sensor corresponds to an optical chain (1212, 1204) having a second focal length, said second focal length being different from said first 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.
