Abstract:
1. An image processing apparatus comprising: a processor coupled to a memory; a receiving unit configured to receive image data; a specifying unit configured to specify a correction amount of the image data for keystone correction processing; a controlling unit configured to control, based on the correction amount specified by the specifying unit, the keystone correction processing on the image data, low-pass filter processing for reducing a predetermined high frequency component of the image data, and edge enhancement processing on the image data, wherein the controlling unit determines a cutoff frequency for the low-pass filter processing based on the correction amount specified by the specifying unit; and an outputting unit configured to output processed image data which is processed based on the controlling by the controlling unit, wherein the edge enhancement processing includes edge extraction by using bandpass filter processing based on a parameter determined by the controlling unit, wherein the parameter is determined based on the correction amount specified by the specifying unit, and wherein the receiving unit, the specifying unit, the controlling unit, and the outputting unit are implemented by the processor.
