Image compensation device for open hole stereoscopic display and method thereof

Abstract

The invention provides an image compensation device for an open hole stereoscopic display and a method thereof. The image compensation device comprises a detection unit, a compensation unit and a stereoscopic image representation unit, wherein the detection unit is used for detecting the position coordinates and the head rotation angle of a viewer; the compensation unit is used for adjusting the width of each image frame according to the position coordinates and the head rotation angle so that the site between the eyebrows between human eyes is located at the border of adjacent image frames; the stereoscopic image representation unit is used for forming corresponding stereoscopic images and displaying the images on a screen according to the width of the image frames after being adjusted. Compared with the prior art, the image compensation device disclosed by the invention can solve the problems of bad image crosstalk and 3D (three-dimensional) result when the head of the viewer rotates, and the projection point of the site between the eyebrows between human eyes of the viewer in the image frame sequence direction is re-located at the border of adjacent image frames through the image frame offset operation in the horizontal direction and the width reducing of the image frame, thus the image crosstalk can be reduced, and the 3D experience result of the viewer is promoted.

Description

technical field [0001] The invention relates to a naked-eye stereoscopic display, in particular to an image compensation device and a compensation method for the naked-eye stereoscopic display. Background technique [0002] Naked-eye 3D stereoscopic display is also called multi-view naked-eye stereoscopic display. Its main principle is to use the parallax characteristics of human eyes to present images with spatial depth and Realistic stereoscopic images that float off-screen. For example, the multi-view glasses-free three-dimensional display adopts lens array technology, accurately aligns the position through moiré interferometry, and provides subtle differences in perspective images for both eyes by changing the transmission direction of light in the horizontal direction, thereby utilizing the parallax of the left and right eyes to achieve Three-dimensional effect. [0003] In the existing technology, some manufacturers use lenticular lens 3D technology (lenticular lens)...

AI Technical Summary

Problems solved by technology

However, when the user's head rotates and the two eyes are not parallel to the 3D TV, the projection of the distance between the two eyes in the horizontal direction is smaller than the width of one image frame, and the center of the eyebrows will also deviate from two adjacent image frames. The crosstalk of the image seen by the user is high at this time, and the 3D image effect will also deteriorate.
