    • An image data correcting device eliminates a back projection image without eliminating an image corresponding to a low-intensity halftone image. An intensity difference detection part detects an intensity difference between first image data corresponding to a part of a predetermined small area and second image data corresponding to the remaining parts of the predetermined small area. A halftone detection part determining whether the first image data corresponds to a halftone image. An intensity change part changes an intensity of the first image data to a predetermined low intensity, when the intensity difference is equal to or smaller than a first predetermined value and the first image data does not correspond to the halftone image and the intensity of the first image data is equal to or smaller than a second predetermined value.
    • 图像数据校正装置消除背投影图像而不消除与低强度半色调图像相对应的图像。 强度差检测部分检测对应于预定小区域的一部分的第一图像数据与对应于预定小区域的剩余部分的第二图像数据之间的强度差。 确定第一图像数据是否对应于半色调图像的半色调检测部分。 当强度差等于或小于第一预定值并且第一图像数据不对应于半色调图像和第一图像的强度时,强度变化部分将第一图像数据的强度改变为预定的低强度 图像数据等于或小于第二预定值。
