<P>PROBLEM TO BE SOLVED: To provide an image processing program and an image processor in which Retinex processing can be carried out at high speed with high precision. <P>SOLUTION: Since a pattern of the reference point in a mask for original image formed by preparation processing of a mask for original image corresponds to a pattern of the reference point in a mask for shrink image, distribution of reflectivity obtained from a shrink image is extremely close to distribution of reflectivity obtained from an original image. Consequently, an appropriate clip range (a clip range extremely approximate to a clip range obtained from an original image) can be obtained from a shrink image and Retinex processing can be carried out at high speed with high precision. <P>COPYRIGHT: (C)2008,JPO&INPIT |
