Patent ID: 7664320

Claim:
An image processing apparatus comprising: an image reading unit that acquires image data from a document; a memory device that accumulates image data; a reuse determining unit that determines whether to reuse the image data; a first image-data processing unit that performs a first image processing on the image data; a second image-data processing unit that performs a second image processing on the image data on which the first image processing is performed; and an interface unit that outputs the image data on which the second image processing is performed, to an image processing unit that is connected to the interface unit, wherein when the reuse determining unit determines to reuse the image data, the first image-data processing unit performs the first image processing that includes unifying characteristics of the image data into predetermined characteristics, the memory device accumulates the image data on which the first image processing is performed, and the second image-data processing unit performs the second image processing, which complies with the image processing unit or a processing mode of the image processing unit of an image output destination, on the image data accumulated in the memory device, and when the reuse determining unit determines not to reuse the image data, the first image-data processing unit performs the first image processing, which complies with the image processing unit or a processing mode of the image processing unit of an image output destination, on the image data, and the second image-data processing unit performs the second image processing, which complies with the image processing unit or a processing mode of the image processing unit of an image output destination, on the image data on which the first image processing is performed.
