Patent ID: 7259878

Claim:
An image processing apparatus, comprising: image-data input means for inputting image data; specific-image determination means for determining whether the image data input by said image-data input means represents a specific image having predetermined characteristics; re-input determination means for determining whether to output a signal urging re-input of the image data input by said image-data input means, said re-input determination means including difficulty determination means for determining whether the determination by said specific-image determination means is difficult, said difficulty determination means comprising difficulty calculation means for calculating a mounting position of a document, wherein said difficulty determination means determines whether the determination by said specific-image determination means is difficult by comparing information about the mounting position to a predetermined threshold, and wherein said re-input determination means determines whether to output the signal urging re-input of the image data based on the determination by said difficulty determination means, wherein said difficulty determination means determines whether the determination by said specific-image determination means is difficult using a scan of the image at a first density and, if it is determined that the determination by said specific-image determination means is not difficult, said specific-image determination means performs a determination using a scan of the image at a second density higher than the first density; and signal output means for outputting the signal urging re-input of the image data, in accordance with a result of the determination by said re-input determination means.
