Patent ID: 7259894

Claim:
An image processing apparatus for inputting photographic image data comprising dot matrix picture elements and performing predetermined image processing thereon, said method comprising: an image data acquiring unit which acquires said photographic image data, an image processing indicator specifying unit which performs predetermined summation processing on all picture elements based on said acquired image data and specifies an image processing indicator, and a processing unit which determines image processing contents based on said specified indicator and performs image processing, wherein said image processing indicator specifying unit comprises a feature amount uniform sampling unit which determines a uniform image processing intensity by uniformly sampling a feature amount in a form of a histogram over a whole image, and a feature amount weighting reevaluation unit which reevaluates said feature amount sampled in said feature amount uniform sampling unit with a predetermined weighting, and in said processing unit, said uniform image processing intensity is determined based on said reevaluated feature amount in a form of a histogram, and image processing is performed with said uniform image intensity.
