In a full-color image scanner having three parallel linear arrays of photosensors, each linear array of photosensors is sensitive to one primary color. With each readout cycle relating to a row of small areas on an original image moving past the scanner, the middle array of the three arrays of photosensors reads out its video data before the other two. This technique allows the arrays of photosensors to be spaced relatively close to each other, and in turn the close spacing of photosensors requires relatively fewer scan lines of video data to be temporarily buffered in the readout process.
