Correction component, mapping method and compensation method for interval of image photosensitive component



The invention provides a correction component for the interval of an image photosensitive component. The component comprises a pixel unit array and a pattern, wherein pixel units are defined by intersecting parallel longitude lines with parallel latitude lines and the pixel unit array is filled with the pixel units; the pattern consists of part of pixel units; the pixel units forming the pattern have a gray scale different from that of other pixel units in the pixel unit array; and the pattern comprises unparallel longitude lines and latitude lines and parallel strips at intervals. A comparison program is set by the characteristic of the pattern; the size and position of the interval of the image photosensitive component are determined according to the consistency of the gray scale of a target pixel unit and a comparison pixel unit; and a scanned object is compensated to optimize the quality of a scanned image.
