An image processing apparatus in which the reusability of digital image data is improved is disclosed. The apparatus includes an image reading unit reading a draft and obtaining the digitized image data; an image writing unit printing image data on a transfer paper; a recording unit recording image data and attached information of the image data; an external I/F unit transmitting and receiving image data and attached information of the image data; a first and a second image data processing units processing the image data from the image reading unit and the recording unit, respectively; and a bus controlling unit connecting each of the units. The first and the second image data processing units match the characteristics of the image data to prescribed characteristics so that the matched image data can be usable for both the image writing unit and the external device.

Image processing apparatus

A disclosed image forming apparatus includes an image scanning unit configured to generate image data by converting light reflected from an optically scanned printed page into electrical signals; an interface configured to receive image data from an external apparatus; an expansion bus to which the image scanning unit and the interface are connected; a bus control unit configured to control the expansion bus; an image data storage unit configured to store the image data; at least one image processing unit connected to the expansion bus and configured to perform an image processing operation on the image data; a task management unit configured to send an image processing request to the image processing unit; and an image writing unit connected to the expansion bus and configured to print the image data on which the image processing operation has been performed by the image processing unit.

Image forming apparatus, image processing unit, image processing method, and recording medium having image processing control program with task management

When image data is determined to be reused, a first image-data processing unit performs a first image processing on the image data, a memory device accumulates the image data on which the first image processing is performed, and a second image-data processing unit performs second image processing on the image data accumulated in the memory device. When the image data is determined not to be reused, the first image-data processing unit performs a first image processing, and the second image-data processing unit performs a second image processing on the image data on which the first image processing is performed.
