ABSTRACT:
A sharpness conversion part is provided in a print inspection apparatus and performs an average-masking operation to weaken a sharpness of object image data to be inspected and that of reference image data. After that, a differential value between these data is acquired. With this operation, an inspection for printing is performed by using image data of which the difference is distinguishable by human's visual property, not considering an invisible differential value which is caused by pixel displacement in subpixel order, and it is therefore possible to efficiently obtain a print inspection result with an accuracy almost as high as that by visual inspection. Thus, a print inspection apparatus can be provided, which is capable of correctly extracting difference to be detected by visual check.
