Embodiment approach 1

[0035] This embodiment describes an image processing method for image processing a moving image composed of a plurality of frame images, and an image processing system and computer program for realizing the image processing.

[0036] First, use figure 1The configuration of the image processing system will be described. In this embodiment, an image processing system including an image display unit will be described as an image processing system. In other words, the image processing system of this embodiment can also be said to be an image display system including an image processing device. figure 1 It is a block diagram showing a configuration example of the image processing system of this embodiment. figure 1 The image processing system 100 shown is a device capable of displaying a moving image composed of a plurality of frame images, and includes an image processing device 101 and an image output device 102 .

[0037] The image processing device 101 is a device that extra...

Embodiment approach 2

[0098] By shooting a moving image with the same focus condition by fixing the camera like a surveillance camera, it is possible to take a moving image with no change in the background. Such dynamic images are for example given by Figure 7A A dynamic image composed of multiple frame images shown. In this embodiment, a method of extracting a moving object from such a moving image will be described.

[0099] In this embodiment, instead of three frame images, a frame image composed of only a background without a moving object (hereinafter referred to as "frame image for background") is prepared. A difference image between the background frame image and the target frame image is created, and the image obtained by binarizing the difference image becomes a mask image ma.

[0100] When making the mask image ma, the difference value (ΔR 1 (x, y), ΔG 1 (x, y), ΔB 1 (x, y)). According to whether the difference is above or below the threshold, the brightness judgment value (α R1 (...

Embodiment approach 3

[0103] When image processing is performed on both the background area and the moving object area, the effect of the image processing on the moving object area may be changed according to the proportion of the moving object area in the frame image. In other words, in moving object image processing, also with Figure 6 The background image processing of the same, according to the ratio Pm of the moving body region, different levels of image processing are performed on the moving body region. In this case, the larger the ratio Pm of the moving object area, the level of image processing (sharpening processing, contrast enhancement processing, etc.) performed in the moving object image processing is set so that the sharpening or enhancing effect of the image is greater That's it.

Abstract

The present invention relates to image processing method, image processing system and computer program. Based on a difference image of three temporally consecutive frame images, a moving object region where a moving object is displayed and a background region are extracted from a central frame image. A processing of becoming a clear image such as contrast enhancement is performed on an image of the moving object region. On the other hand, a blurring processing such as an averaging processing is performed on an image of the background region. The image of the background region is blurred in this blurring processing so that the degree of blurring increases as the ratio of the moving object region in the frame image is high.

Description

technical field [0001] The present invention relates to an image processing method for moving images, an image processing system for performing image processing for moving images, and a computer program for performing image processing for moving images. Background technique [0002] In recent years, high-resolution and large-screen liquid crystal display devices and plasma display devices capable of viewing high-definition images have become widespread. Therefore, the requirements for image quality are getting higher and higher, and one of the requirements is a sense of presence and a sense of distance (sense of distance). And by improving the sense of three-dimensionality and depth, the sense of presence can be improved. [0003] For example, a photo whose focus is on the screen as a whole lacks a sense of distance and three-dimensionality. Then, in the prior art, in order to make the photos (still images) taken by the video capture device have a sense of distance and a s...
