Image processing method, image display system, and computer program

摘要

A moving object display region where a moving object is displayed and a background display region are extracted based on a difference image of frame images. Blurring processing such as averaging processing is performed on an image in the background display region. Processing for further sharpening an image, such as contrast enhancement, is performed on an image in the moving object display region.

1. An image processing method for processing a moving image including a plurality of frame images, comprising the steps of:
extracting a moving object display region where a moving object is displayed from image at least one frame image; determining whether the moving object display region accounts for more than a value of proportion of a target frame image; and performing a first kind of image processing on a pixel included in the moving object display region and performing a second kind of image processing on a pixel which is not included in the moving object display region in the frame image to generate a correction frame image when the moving object display region accounts for less than a value of proportion of a frame image, displaying the target frame image on an image display portion without forming the correction frame image when the moving object display region accounts for more than the value of proportion of the target frame image, wherein the first kind of image processing is different from the second kind of image processing, wherein the second image processing comprises blurring processing, and wherein at least one kind of image processing among contrast conversion processing for reducing contrast and mosaic processing is performed as the blurring processing.
