IMAGE PROCESSING APPARATUS AND METHOD, AND IMAGE READING APPARATUS

摘要

An object of the present invention is to provide an image processing apparatus and an image processing method both off offering a high-precision and general-purpose capability of identifying an image and performing appropriate processing depending on whether identification is effected, In the image processing apparatus and image processing method, image data is detected in visible and invisible light reflected from each of a target pixel and surrounding pixels. Based on the image data detected in visible and invisible light, a specific pattern is identified. The specific pattern appears substantially the same in color as a surrounding area under visible light but different in characteristic therefrom under invisible light, which is identified using the image data of the target pixel and surrounding pixels provided by a detector. The image processing apparatus is controlled depending on whether the identification is effected.
