VIDEO FORMAT DETERMINATION DEVICE, VIDEO FORMAT DETERMINATION METHOD, AND VIDEO DISPLAY DEVICE

摘要

There is provided a video format determination device including a video input unit that receives video having a feature amount for each pixel, a region representative value calculation unit that divides a left-eye video region and a right-eye video region in a three-dimensional video format to be determined in input video into small regions, and then computes representative values of feature amounts of the respective small regions for each of the left-eye video region and the right-eye video region, a correction value calculation unit that calculates a correction value to correct the representative values, a data correction unit that corrects the representative values, an inter-region correlation calculation unit that calculates the correlation between the left- and right-eye video regions, and an evaluation determination unit that evaluates the correlation to determine whether input video is in the three-dimensional video format.

主权项

1. A video format determination device comprising:
a video input unit configured to receive at least one video having a feature amount for each pixel; a region representative value calculation unit configured to divide a left-eye video region and a right-eye video region in a three-dimensional video format to be determined in input video into a plurality of blocks having M rows and N columns, respectively, and compute representative values of feature amounts of the respective plurality of blocks for each of the left-eye video region and the right-eye video region; a correction value calculation unit configured to calculate a correction value to correct the representative values based on an average value of the feature amounts of the left-eye video region and an average value of the feature amounts of the right-eye video region; a data correction unit configured to correct the representative values of the respective plurality of blocks computed for one of the left-eye video region and the right-eye video region using the correction value; an inter-region correlation calculation unit configured to calculate the correlation between the left-eye video region and the right-eye video region by cumulatively adding differences of the representative values of the corresponding plurality of blocks in the left-eye video region and the right-eye video region; and an evaluation determination unit configured to evaluate the correlation between the left-eye video region and the right-eye video region to determine whether the input video is in the three-dimensional video format or a two-dimensional video format.
