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

影像感光组件的间隙的校正用组件、对应方法与补偿方法

Abstract

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.
本发明提供一种影像感光组件的间隙的校正用组件,包含一像素单位数组与一图案,利用平行的经线与平行的纬线相交以定义出像素单位布满像素单位数组,图案由部分的像素单位所构成,且构成图案的像素单位具有一灰阶不同于像素单位数组中的其它像素单位,且其中图案包含不平行经线及纬线且彼此平行间隔的条状。利用图案的特性设定比对程序,以目标像素单位与比对像素单位的灰阶是否一致来应对出影像感光组件的间隙大小与位置,进而对扫描对象进行补偿,以优化扫描影像的质量。
