Abstract:
1. An image processing apparatus which processes a moving image comprising successive frame images, comprising: a unit configured to obtain a frame image of interest as an input image, and to obtain a frame image subsequent to the frame image of interest as a subsequent image; a unit configured to obtain N replicated images from the input image; a generating unit configured to generate a low-frequency enhanced image whose low-frequency component is enhanced, from the replicated image by using a filter for enhancing a low-frequency component; a subtraction unit configured to generate a high-frequency enhanced image whose high-frequency component is enhanced, from the low-frequency enhanced image and the replicated image; a synthesizing unit configured to generate a high-frequency output image by synthesizing the high-frequency enhanced image and the low-frequency enhanced image at a predetermined ratio; and an output unit configured to select and output one of the low-frequency enhanced image and the high-frequency output image in place of each of the replicated images, said generating unit comprising a unit configured to obtain a motion vector of an object depicted in the input image and the subsequent image, and a filter unit configured to generate the low-frequency enhanced image, when processing a pixel at a pixel position P in the replicated image, by performing, for each pixel position in the replicated image, a process of specifying a pixel position Q spaced apart from the pixel position P in the replicated image by a predetermined distance in an opposite direction to the motion vector, a process of applying the filter to pixels around the specified pixel position Q in the replicated image, to obtain a pixel value at the pixel position P in the low-frequency enhanced image.
