Abstract

An image processing apparatus of the present invention inputs image data representing an image, discriminates whether the image represented by the input image data is a first predetermined image, and discriminates whether the image represented by the input image data is a second predetermined image different from the first predetermined image, the above-mentioned two discrimination performing discriminating operation parallelly.
