摘要： A classifying of an input image into a business graphic image or a photo image, such as in image calibration of the image. A system classifying an input image into at least one of a business graphic image and a photo image includes a color space transform unit transforming the input image into components of a lightness-saturation color space, a lightness analysis unit calculating a lightness frequency distribution of lightness components among the transformed components, a saturation analysis unit calculating an average of saturation components among the transformed components, and an image classification unit comparing an estimation function using the calculated lightness frequency distribution and the average of the saturation components and a threshold value so as to classify the input image.
