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

[0072] 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.

[0073] First of all, it needs to be explained that in the embodiment of the present invention, the images corresponding to the viewer's left eye and right eye respectively for 3D display are referred to as 3D left-eye images and 3D right-eye images. Usually, in practical applications In, for example, in a 3D film source, the 3D left-eye image and the 3D right-eye image are placed on one film source, and the film source is called a 3D image. Both the 3D left-eye image and the 3D right-eye image contain specific image content and image content other than the specific image content (the embodiment of the present invention refers to it as background image content), and these two parts can be separated, that is, the 3D left-eye The eye image and the 3D right-...

Abstract

The present invention discloses an image processing method and apparatus. The image processing method comprises the following steps that: target images of preset image content is obtained, all regions in the target images except the preset image content are transparent regions; preset processing regions in the target images are determined; 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; the changed target images and background images are synthesized, wherein the background images include a left-eye background image and a right-eye background image, and therefore, a 3D left-eye image and a 3D right-eye image can be obtained; and 3D display is performed based on the 3D left-eye image and the 3D right-eye image.

Description

technical field [0001] The present invention relates to the technical field of image processing, 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 experi...
