IMAGE PROCESSING APPARATUS, IMAGE FORMING APPARATUS, AND COMPUTER READABLE MEDIUM
First Claim
1. An image processing apparatus comprising:
- a reception unit that receives two image data to be compared;
an acquisition unit that acquires character sizes of characters contained in the two image data received by the reception unit;
an enlarging/reducing unit that enlarges or reduces the image data received by the reception unit such that the character sizes of the characters contained in the two image data acquired by the acquisition unit coincide with each other; and
a detector that detects a difference between the two image data which have been enlarged or reduced by the enlarging/reducing unit such that the character sizes of the characters contained in the two image data coincide with each other.

Abstract
An image processing apparatus includes a reception unit, an acquisition unit, an enlarging/reducing unit, and a detector. The reception unit receives two image data to be compared. The acquisition unit acquires character sizes of characters contained in the two image data received by the reception unit. The enlarging/reducing unit enlarges or reduces the image data received by the reception unit such that the character sizes of the characters contained in the two image data acquired by the acquisition unit coincide with each other. The detector detects a difference between the two image data which have been enlarged or reduced by the enlarging/reducing unit such that the character sizes of the characters contained in the two image data coincide with each other.

8. An image forming apparatus comprising:
-
a reception unit that receives two image data to be compared; an acquisition unit that acquires character sizes of characters contained in the two image data received by the reception unit; an enlarging/reducing unit that enlarges or reduces the image data received by the reception unit such that the character sizes of the characters contained in the two image data acquired by the acquisition unit coincide with each other; a detector that detects a difference between the two image data which have been enlarged or reduced by the enlarging/reducing unit such that the character sizes of the characters contained in the two image data coincide with each other; a generation unit that generates a difference image that indicates the difference between the two image data detected by the detector; and an output unit that outputs the difference image generated by the generation unit.

9. A non-transitory computer readable medium storing a program causing a computer to execute a process comprising:
-
receiving two image data to be compared; acquiring character sizes of characters contained in the received two image data; enlarging or reducing the received image data such that the character sizes of the characters contained in the acquired two image data coincide with each other; and detecting a difference between the two image data which have been enlarged or reduced such that the character sizes of the characters contained in the two image data coincide with each other.
