Embodiment Construction

[0026] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings, so that those skilled in the art can better understand the present invention. It should be noted that in the following description, when detailed descriptions of known functions and designs may dilute the main content of the present invention, these descriptions will be omitted here.

[0027] figure 1 It is a functional block diagram of a specific embodiment of the method for interpolating 3D HALF format images in the present invention.

[0028] In this implementation, if figure 1 As shown, in the process of realizing left and right eye image interpolation, the 3D HALF format image is first separated from the left and right eye images, and the horizontal direction interpolation or vertical direction interpolation is selected according to the type of 3D HALF format. Interpolation operation on .

[0029] The size of the 3D HALF format image is M×N, separ...

Abstract

The invention discloses a method for interpolation in a three-dimension (3D) HALF form image, and by introduction of a piecewise function, a pixel value of an interpolation point is determined by selecting an appropriate computing formula of the pixel value of the interpolation point from the piecewise function according to the continuity of the image at the interpolation point. The method overcomes the defects of serious granular sensation of images in left eyes and right eyes which is caused by a nearest neighbor interpolation method in 3D HALF form image interpolation methods of the prior art as well as serious high frequency degeneration of images in left eyes and right eyes and blurred images which are caused by a bilinear interpolation method. Amplification effects of images in left eyes and right eyes, which are processed by the method, reserve information of all frequency bands of images well, edges are sharpened, details are clear, image effects after images are processed according to a bicubic interpolation algorithm are basically achieved, the operation amount is small, and the hardware implementation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of digital image processing and video display, and more specifically relates to a method for interpolating 3D HALF format images. Background technique [0002] The 3D HALF format enables one image to contain the information of two images, which are respectively used for the left-eye image and the right-eye image in the 3D video. However, the pixel size of the separated left and right eye images is half of the original 3D HALF format image, which does not meet the video display requirements, so the separated left and right eye images need to be interpolated and enlarged. [0003] Image interpolation is one of the most important technologies in 3D HALF format image processing. Commonly used image interpolation methods include nearest neighbor interpolation, bilinear interpolation, and bicubic interpolation. [0004] 1. Nearest neighbor interpolation method [0005] The nearest neighbor interpolation method i...
