The method may also include setting, by the one or more processors, the depth of the display equal to the environment depth.

A video signal is processed in a video device (50). The video signal transfers video data representing either three dimensional video [3D] content formatted according to a 3D format or 2D content formatted according to a 2D format. The video signal has a 2D frame and a control structure of a 2D format for being compatible with existing distribution systems. The device has a processor (52) for providing a 3D status signal indicative of the format of the video signal. The processor determines a respective format score for at least one of the possible 3D formats by processing the video data according to respective predetermined format properties for deriving and comparing respective 3D subframes, and sets the 3D status signal based on an assessment of the format score to indicate the format of the video signal. Advantageously the 3D format is detected automatically and a 3D display can be controlled accordingly.

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.
