Image processing apparatus and method utilizing high and low frequency component images

摘要

Each frame image is acquired as an input image. An image obtained by emphasizing high frequency components in the input image is generated as a high frequency component emphasized image, a composite image is generated by compositing the input image and an input image of a previous frame before the input image, and an image including low frequency components in the composite image is generated as a low frequency component image. Then, the high frequency component emphasized image and low frequency component image are alternately output as images of sub-frames of the input image.

1. An image processing apparatus comprising:
an acquisition unit configured to acquire an image; a first composition unit configured to generate a first composite image by compositing the acquired image and a previous image which is acquired before the acquired image at a first composition ratio and to generate a second composite image by compositing the acquired image and the previous image at a second composite ratio; a first generation unit configured to generate an image obtained by emphasizing high frequency components in the first composite image as a high frequency component emphasized image; a second generation unit configured to generate an image which has reduced high frequency components in the second composite image as a low frequency component image; a second composition unit configured to generate a third composite image by compositing the high frequency component emphasized image and the low frequency component image at a third composite ratio and to generate a fourth composite image by compositing the high frequency component emphasized image and the low frequency component image at a fourth composite ratio; an output unit configured to alternately output the third composite image and the fourth composite image as sub-frame images of the acquired image; and a composite ratio adjustment unit configured to adjust the first composite ratio, the second composite ratio, the third composite ratio, and the fourth composite ratio for respective frames.
