IMAGE PROCESSING APPARATUS, METHOD AND PROGRAM

An image processing apparatus includes a circumstance vector generation unit configured to acquire information indicating circumstances, to digitize the information, and to generate a circumstance vector, a conversion parameter calculation unit configured to weighted-add several conversion parameters specified by the circumstance vector among a plurality of previously prepared conversion parameters for image conversion, and a converted image generation unit configured to perform image conversion using the conversion parameters obtained by the weighted-adding with respect to an original image to be processed so as to generate a converted image.
