PROBLEM TO BE SOLVED: To provide an image generating apparatus, an image generating method, and a computer program for generating an image by removing only a noise portion reliably without losing sharpness of an edge portion. SOLUTION: A reduced image is generated by reducing the multi-valued image imaged by an imaging means and smoothing processing is executed on the reduced image. An edge image is generated from the reduced image, and edge angle information concerning edge angles is generated in pixel units from the generated edge image. A synthesizing rate of the multi-valued image and the smoothed reduced image is calculated in pixel units of the reduced image on the basis of the generated edge angle information. An enlarged image is generated by enlarging the smoothed reduced image to an identical scale of the multi-valued image, and the synthesizing rate calculated in pixel units of the reduced image is converted into a synthesizing rate in pixel units of the enlarged image. The multi-valued image and the enlarged image are synthesized on the basis of the converted synthesizing rate. COPYRIGHT: (C)2009,JPO&INPIT |
