Image processing apparatus, image forming apparatus, and computer readable medium
First Claim
1. An image processing apparatus comprising:
- a reception unit configured to receive two image data to be compared;
an acquisition unit configured to acquire character sizes of characters contained in each of the two image data received by the reception unit;
an enlarging/reducing unit configured to enlarge or reduce at least one of the two image data received by the reception unit such that the character sizes of the characters contained in each of the two image data acquired by the acquisition unit coincide with each other; and
a detector configured to detect a difference between the two image data at least one of which have been enlarged or reduced by the enlarging/reducing unit such that the character sizes of the characters contained in each of 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 configured to receive two image data to be compared; an acquisition unit configured to acquire character sizes of characters contained in each of the two image data received by the reception unit; an enlarging/reducing unit configured to enlarge or reduce at least one of the two image data received by the reception unit such that the character sizes of the characters contained in each of the two image data acquired by the acquisition unit coincide with each other; a detector configured to detect a difference between the two image data at least one of which have been enlarged or reduced by the enlarging/reducing unit such that the character sizes of the characters contained in each of the two image data coincide with each other; a generation unit configured to generate a difference image that indicates the difference between the two image data detected by the detector; and an output unit configured to output the difference image generated by the generation unit. - View Dependent Claims (12, 13)

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 each of the received two image data; enlarging or reducing at least one of the two received image data such that the character sizes of the characters contained in each of the acquired two image data coincide with each other; and detecting a difference between the two image data at least one of which have been enlarged or reduced such that the character sizes of the characters contained in each of the two image data coincide with each other. - View Dependent Claims (14, 15)
