Abstract
An image processing apparatus has a pixel data input unit, and a processing unit for processing pixel data input from the input unit. The processing unit has a discriminating unit for discriminating an image type of the input pixel data. The discriminating unit has a first discriminator for discriminating the image type of a pixel of interest in a first mode using data of the pixel of interest and pixel data adjacent to the pixel of interest, and a second discriminator for discriminating the image type of the pixel of interest in a second mode different from the first mode. The unit discriminates the image type of the pixel of interest using the discrimination results of the first and second discriminators.
