AI Technical Summary

Problems solved by technology

Because the left eye is turned on when the right eye is turned off, the subsequent luminescence of the right image is only seen by the left eye, thereby destroying the stereoscopic effect (with Figure 4 Compared)

Embodiment Construction

[0035] Preferred embodiments of the present invention can refer to Figure 6 to Figure 10 Explain clearly in turn.

[0036] The starting point of the first embodiment of the present invention is to separate the 3D video according to the above principle and perform a specific general auxiliary field encoding. The principle of specific general subfield coding is described in the applicant's previous European patent application EP 01103185.3. For the purposes of disclosing the present application, reference has also been made to earlier applications. The basic idea behind this concept is to replace two images with three: that is, replace the right and right images with a specific right image, a specific left image, and a generic image.

[0037] This concept is based on the fact that two views viewed from the same image are very similar. A pair of left and right images (R, L) can be transformed into three images: right specific (R'), left specific (L') and common (C'). This co...

Abstract

The shutter glasses controlled by PDP can be successfully used on the plasma display screen to make the left and right images display stereoscopic images in a short rotation process, but the phosphorus time lag effect destroys the stereoscopic vision. The frame period of the stereoscopic image is divided into at least one left period of the left image and at least one right period of the right image, respectively. Two kinds of images are similar, determine its common part from a pair of corresponding pixels, the subfield code word of left and right images is determined as a part of specific left / right subfield (SLSF, SRSF) and common subfield ( CSF). A common subfield (CSF) is placed behind multiple left and right subfields of the left and right images so that the phosphorus skew effect is invisible to the eyes.

Description

technical field [0001] The invention relates to a method and a device for processing video frames for stereoscopic display in a display device having a large number of light-emitting units, in particular a plasma display panel (PDP). Each light emitting element shall be a pixel in the video frame. Each video frame includes two images, one left and one right, and the duration of the video frame is divided into several secondary fields. During this period, the light-emitting element for light emission / generation is excited for a small pulse corresponding to the sub-field code for controlling brightness. Background technique [0002] The three-dimensional perspective image seen by the human eye system is based on the two eyes that are juxtaposed on the left and right. Each eye has a slightly different perspective on the same field of view. Two separate images are sent to the brain by pressing figure 1 way to deal with. When two images reach the back of the brain at the sam...
