Abstract
The image verification method for a print image and a representation image judges a degree of similarity between any individual frames using all of or a part of input image data, sets image processing conditions such that print finishing or representation images of respective frames with high similarity therebetween are the same with or similar to each other, represents in a verification picture plane a verification image of the frame which has been subjected to image processing under the thus set image processing conditions and performing similarity verification processing such that, when a user's correction of the image processing conditions is performed on a certain frame, the image processing conditions of a similar frame can automatically be subjected to the user's correction with different intensity changeable in accordance with the degree of similarity to represent the verification image anew. The method decreases uneven finishing among similar frames, provides the print or the representation image of stable quality as well as increases verification efficiency by a user or an operator.
