  • Patent number: 5296945
    Abstract: Video ID photo printing apparatus corrects the complexion of a person serving as an object into a desired color without any influences caused by controlling an illumination light source and the various control section of a video image pickup apparatus, printer characteristics, and the like. In order to extract the complexion data of the person serving as an object photographed by a color TV camera, a skin-color portion in a face image is detected by a detection point setting unit. A comparator compares the detected data value with a data value of a desired standard skin color formed in advance and stored in a standard color memory. The skin color of the picked up face image is converted into a desired skin color by a look-up table in accordance with a comparison result, and the data of the desired skin color is written in a frame memory. Thereafter, the face image which is subjected to color conversion is printed by a full-color printer.
