Patent ID: 8547602

Claim:
An image processing apparatus comprising: a storage unit configured to store original image data; a readout unit configured to read out the original image data from the storage unit, while dividing the original image data into a plurality of divided image data; a plurality of image processing units configured to perform image processing on the plurality of divided image data to generate a plurality of processed image data; an image combining unit configured to combine the plurality of processed image data to generate combined image data; an output unit configured to output the combined image data; and a control unit configured to, if the original image data is needed to be shifted, control the readout unit to read out the original image data to include an overlapping region such that the plurality of divided image data partially overlap each other, and control the image combining unit to delete an unnecessary pixel according to the shift, and, if the original image data is not needed to be shifted, control the readout unit to read out the original image data not to include the overlapping region, and control the image combining unit not to delete the unnecessary pixel.
