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 at least one frame image; and
performing different kinds of image processing on a pixel included in the moving object display region and a pixel which is not included in the moving object display region in the frame image to generate a correction frame image,wherein the image processing performed on the pixel which is not included in the moving object display region is blurring processing.

Abstract
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.

2. An image processing method for processing a moving image including a plurality of frame images, comprising the steps of:
-
generating a first binary difference image based on a difference image between a target frame image to be subjected to correction and a frame image which is k frame or k frames before the target frame image where k is one of 1 and 2; generating a second binary difference image based on a difference image between the target frame image and a frame image which is k frame or k frames after the target frame image; extracting a moving object display region from a logical product of the first binary difference image and the second binary difference image to generate a mask image formed from the moving object display region and a background display region; and performing different kinds of image processing on a pixel in the same position as a pixel included in the moving object display region and a pixel in the same position as a pixel included in the background display region in the target frame image to generate a correction frame image, wherein the image processing performed on the pixel in the same position as the pixel included in the background display region is blurring processing. - View Dependent Claims (4)
