AI Technical Summary

Problems solved by technology

However, in general stereoscopic images, the order of the left / right eye images is not specified, nor is the position of the left / right eye images specified. Therefore, in order to correctly transmit the left / right eye images to the left and right eyes, It is necessary to detect the sequence or position of the left / right eye images of the stereoscopic image

Embodiment Construction

[0013] Please refer to figure 1 , figure 1 It is a schematic block diagram of an image frame detection device 100 according to an embodiment of the present invention. The image detection device 100 includes a scaling unit 105 , a storage unit 110 , a calculation unit 115 , a determination unit 120 and a processing unit 125 . The calculation unit 115 is used for an input image Y in Comparing a corresponding target area in the two consecutive images, performing block comparison to calculate a plurality of block comparison differences, and selecting a smaller block comparison difference from these block comparison differences, Then, a motion vector is determined according to the comparison difference of the smaller block. In a preferred embodiment, the comparison difference of the smaller block is a minimum block comparison difference among these block comparison differences value. The determining unit 120 is used for performing left / right eye image determination on the image...

Abstract

A method for detecting left-eye / right-eye images is capable of effectively and accurately detecting a sequence or positions of left-eye / right-eye image frames of a stereo image signal. The method includes performing block matching on a target block corresponding to two consecutive image frames of an image signal to determine a motion vector; and performing left-eye / right-eye image determination on a current image frame from the two consecutive image frames according to the motion vector.

Description

technical field [0001] The present invention relates to an image frame detection mechanism, in particular to an image frame detection device and method for performing left / right eye image judgment. Background technique [0002] With the evolution and development of technology, in order to provide a more realistic and natural display effect, the development of display technology has begun to pursue the 3D stereoscopic image display effect with a better sense of presence; and the stereoscopic image display technology mostly uses the concept of screen segmentation, Divide the video screen into left-eye screen and right-eye screen with different viewing angles, and use the stereoscopic image display to transmit the left / right eye screen to the left eye and right eye respectively, and finally project the two screens through the human brain to generate a three-dimensional effect , so the order of the left / right eye frames in general stereoscopic images is interleaved with each oth...
