Abstract:
1. An image processing apparatus, comprising: an image input configured to input original image data obtained by an image input device; an image processor provided independently from the image input device and configured to extract feature information of the original image from the original image data, and to generate normalized image data using the feature information by selecting image processing to be applied to the original image data based on the feature information without requiring characteristic information indicating the characteristics of the image input device, and applying the selected image processing to remove image variations from the original image data caused by the characteristics of the image input device, wherein the image processor includes: an image processing controller configured to select at least one of a plurality of sub-processors and to cause the selected sub-processor to apply the image processing to generate the normalized image data, the sub-processors including: a halftone converter configured to convert the original image data from halftone to continuous tone using the feature information when selected by the image processing controller; a tone corrector configured to adjust color contrast in the original image data using the feature information when selected by the image processing controller; a character color corrector configured to adjust character color in the original image data using the feature information when selected by the image processing controller; and an image distortion corrector configured to correct image distortion in the original image data using the feature information when selected by the image processing controller; and an image output configured to output the normalized image data through an image output device.
