Embodiment 1

[0042] figure 2 It is a specific flowchart of an image processing method provided by an embodiment of the present invention. Such as figure 2 As shown, a method for image processing, applied to a display unit including an optical magnification component, includes the following steps:

[0043] Step 201, determine the edge area in the image area, and the image area outside the edge area is the middle area;

[0044] Step 202, performing image reduction processing on the image in the edge region toward the direction of the image boundary, and performing image enlargement processing on the image in the middle region toward the direction of the image boundary;

[0045]Step 203, displaying the reduced and enlarged image through the display unit, so that the display unit presents an image with the same proportion.

[0046] Wherein, the display unit may be a splicing unit in the splicing wall, or a separate display device; in a specific implementation, the optical magnification co...

Embodiment 2

[0059] In actual operation, when the display unit is a splicing unit of the splicing wall, such as image 3 As shown, an image processing method provided by the present invention is applied to a display unit including an optical magnification component, including the following steps:

[0060] Step 301, acquiring the original image to be displayed on the video wall;

[0061] Step 302, segmenting the obtained original image to obtain the image to be displayed by each display unit;

[0062] Step 303, according to the width and magnification of the optical magnification component, determine the reduced area in the display unit, and the area of ​​the display unit outside the reduced area is the enlarged area;

[0063] Step 304, according to the size of the image, the width of the display unit, the width of the seam of the display unit, and the size of the reduced area, determine the number of pixels in one direction of the image in the edge area of ​​the image;

[0064] Step 305,...

Embodiment 3

[0090] In actual operation, when the display unit is a splicing unit of the splicing wall, such as Figure 4 As shown, another image processing method provided by the present invention is applied to a display unit including an optical magnification component, including the following steps:

[0091] Step 401, acquiring the original image to be displayed on the video wall;

[0092] Step 402, segmenting the obtained original image to obtain the image to be displayed by each display unit;

[0093] Step 403, according to the width and magnification of the optical magnification component, determine the reduced area of ​​the display unit, and the area of ​​the display unit outside the reduced area is the enlarged area;

[0094] Step 404, according to the size of the image, the width of the display unit, the width of the seam of the display unit, and the reduced area of ​​the display unit, determine the number of pixels in one direction of the image in the edge area of ​​the image; ...

Abstract

The invention discloses an image processing method and device. The image processing method is applied to a display unit comprising an optical amplification part. The method includes the steps that a marginal area in an image area is determined, and the image area except the marginal area serves as a middle area; image reduction processing is conducted on images in the marginal area in the image boundary direction; image magnification processing is conducted on images in the middle area in the image boundary direction; the images which are reduced and magnified are displayed through the display unit, and therefore the display unit can present images in the same proportion. According to the image processing method and device, under the effect of the optical amplification part, the images with the marginal areas reduced are magnified in vision, the magnification proportion of the images is equal to that of the images in the middle area, so that the display unit presents the images which are consistent in proportion, and therefore the images are displayed in a non-deformation mode in overall vision.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing method and device. Background technique [0002] At present, in the field of large-screen image display, splicing walls have been widely used. The splicing wall is formed by splicing various small-area display screens, and each small-area display screen is a splicing unit of the splicing screen. The splicing wall can improve the resolution and increase the display area, so as to fully meet the needs of customers for centralized information display, centralized monitoring, and centralized command and dispatch. [0003] Since most of the current splicing walls are spliced ​​by multiple display units, there are borders or non-display areas in the display units, resulting in joints that cannot display images between adjacent display units, which seriously affects the display effect of the splicing wall. . [0004] The image magnification method is a meth...
