Problems solved by technology

[0003] When displaying an image through naked-eye 3D display technology, since the displayed image is a compressed image, data will be missing, and the edges of certain areas in the image will have jagged edges
For example, on a naked-eye 3D display device, if a 3D image with text is displayed, the aliasing phenomenon at the edge of the text area will be very obvious, thus bringing a very bad viewing experience to the user
[0004] At present, there is no good solution for how to reduce the aliasing phenomenon in the image when displaying the image through the naked-eye 3D display technology

Embodiment Construction

[0055] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0056] First of all, it needs to be explained that, in the embodiment of the present invention, each pixel in the left-eye target image and the right-eye target image can use three pixels: R (red, red), G (green, green), B (blue, blue) Of course, it can also be represented by other color channels. In the embodiment of the present invention, three color channels of red, green and blue are used for illustration.

[0057] In the embodiment of the present invention, the target image for the left eye and the target image for the right eye are images supporting 3D display or glasses-free 3D display.

[0058] In the embodiment of the present invention, the left-eye target image and the right-eye target image contain some image content, such as text, and when th...

Abstract

The present invention discloses an image processing method and apparatus. The method comprises the following steps that: a left-eye target image and a right-eye target image for performing 3D display are acquired; preset processing regions are determined in the left-eye target image and the right-eye target image; as for each pixel in each preset processing region, some pixels are adopted as first background pixels, the absolute value of the difference value of the pixel value of each of the pixels and any one of N preset pixel values is larger than a threshold value, and the transparency of first target pixels adjacent to the first background pixels in the preset processing regions are changed to be first transparency, and the absolute value of the difference value between the pixel value of the first target pixels and any one of the N preset pixel values is smaller than or equal to the threshold value; and 3D display is performed according to the processed left-eye target image and the processed right-eye target image.

Description

technical field [0001] The present invention relates to the technical field of stereoscopic display, in particular to an image processing method and device. Background technique [0002] At present, the naked-eye 3D (3-dimensional, three-dimensional) display technology has become more and more mature. The naked-eye 3D display technology includes light barrier technology and lenticular lens technology. The images are refracted in different directions, so that the visual images of the user's left eye and right eye are separated, so that the user can see 3D images. [0003] When an image is displayed through the naked-eye 3D display technology, since the displayed image is a compressed image, data will be missing, and the edges of certain areas in the image will produce jagged phenomena. For example, if a 3D image with text is displayed on a naked-eye 3D display device, the jagged phenomenon at the edge of the text area will be very obvious, thus bringing a very bad viewing ex...
