Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] In one embodiment, such as figure 1 As shown, a depth adjustment method for converting a 2D image to a 3D image, the method completely depends on a computer program and can run on a computer system based on the von Neumann system.

[0034] The method includes:

[0035] Step S102, acquiring the macroblock in the image, acquiring the initial depth value of the macroblock, and finding the minimum initial depth value and the maximum initial depth value therefrom.

[0036] A macroblock in an image is a pixel area in the image. For example, if the size of the macroblock is 8×8 pixels, it means t...

Abstract

The invention provides a depth adjusting method for converting a 2D image to a 3D image. The method includes the steps of obtaining macro blocks in the 2D image, obtaining initial depth values of the macro blocks, finding out the minimum initial depth value and the maximum initial depth value, obtaining an average depth value through calculation according to the initial depth values of the macro blocks, normalizing the depth values of the macro blocks to be the gray values ranging from 0 to 255 in a nonlinear mode according to the average depth value, the minimum initial depth value and the maximum initial depth value, and converting the 2D image to the 3D image according to the normalized depth value. The invention further provides a depth adjusting device for converting the 2D image to the 3D image. The depth adjusting method and device for converting the 2D image to the 3D image can improve the 3D effect.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a depth adjustment method and device for converting a 2D image into a 3D image. Background technique [0002] In the traditional technology, the depth value calculated by the 2D image to 3D image algorithm is not stable enough in the time domain, and the value range is large. The shaking is too severe and the 3D effect is poor. Contents of the invention [0003] Based on this, it is necessary to provide a depth adjustment method for converting a 2D image into a 3D image that can improve the 3D effect. [0004] A depth adjustment method for converting a 2D image to a 3D image, comprising: [0005] Obtaining a macroblock in the 2D image, obtaining an initial depth value of the macroblock, and finding a minimum initial depth value and a maximum initial depth value therefrom; [0006] calculating an average depth value according to the initial depth value of the...
