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] 首先需要说明的是,本发明实施例中,将用于进行3D显示的分别对应于观看者左眼和右眼的图像称为3D左眼图像和3D右眼图像,通常情况下,在实际应用中,例如在3D片源中,3D左眼图像和3D右眼图像是放置在一张片源上的,该片源称之为3D图像。3D左眼图像和3D右眼图像均包含特定图像内容和特定图像内容之外的图像内容(本发明实施例将之称为背景图像内容),且这两部分内容是可以分离的,即3D左眼图像和3D右眼图像可以是这两部分图像内容所合成的,本发明实施例中将包括特定图像内容之外的图像内容称之为3D左眼背景图像和3D右眼背景图像。举例而言,特定图像内容可以为文字,例如,在3D视频中,相同的背景图像下,文字是变化显示的,比如水平 / 垂直滚动的,或者动态更新的。

[0074] 也就是说,一幅3D左眼图像或者一幅3D右眼图像可以单幅图像,即一幅图像包括所有需要显示的内容;一幅3D左眼图像或者一幅3D右眼图像还可以为多幅图像的组合,该组合中的每幅图像分别包含不同内容,在显示时,多幅图像同时显示,从而形成一幅完整的3D左眼图像或者3D右眼图像。

[0075] 举例来说,一幅3D左眼图像或者一幅3D右眼图像由两幅图像组成,一幅图像中只包括字幕,一幅图像中包括需要显示的背景。在显示时,两幅图像同时显示,从而显示出包含字幕的图像。

[0076] 现有技术中,在进行3D显示时,人眼所观看到的立体图像中,特定图像内容边缘的锯齿现象比较明显,例如文字的边缘,用户的观看体验较差。

[0077] 有鉴于此,本发明实施例提供一种图像处理方法,首先将预设图像内容转化输出为一张目标图像,该目标图像中仅包括特定图像内容,该目标图像中除所述预设图像内容之外的区域均为透明区域,然后对目标图像中的预设图线内容的边缘进行处理,能够有...

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...
