Embodiment Construction

[0046] Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0047] figure 1 A structure of a stereoscopic video display system 1 to which embodiments of the present disclosure can be applied is schematically depicted. The stereoscopic video display system 1 includes: a liquid crystal display 10 for alternately displaying left-eye video L and right-eye video R in a very short period; and shutter glasses 20 worn on the observer's head.

[0048] The liquid crystal display 10 includes: a liquid crystal display panel 11, a backlight 12, a video signal processing unit 13, a shutter control unit 14 for controlling the on / off timing of the shutter mechanism of the shutter glasses 20, a timing control unit 15, a backlight control unit 16, and a data driver 17 and gate driver 18. In this embodiment, the liquid crystal display 10 is based on the input video signal D in display and output video, the input video signal D in ...

Abstract

A video signal processing device, a video signal processing method, and a computer program. The video signal processing device comprises: a histogram detection unit, which detects the histogram of the brightness distribution of any one of the left-eye video signal and the right-eye video signal in the input stereoscopic video signal; the gamma curve calculation unit, based on the histogram detection The histogram detected by the unit calculates a gamma curve; and a gamma curve output unit corrects the left eye video signal and the right eye video signal based on the gamma curve calculated by the gamma curve calculation unit.

Description

technical field [0001] The present disclosure relates to a video signal processing device, a video signal processing method, and a computer program for processing stereoscopic video formed of left-eye video signals and right-eye video signals, and in particular, to a method for correcting image quality of stereoscopic video A video signal processing device, a video signal processing method, and a computer program. Background technique [0002] By displaying video using the parallax of the left and right eyes, a stereoscopic video represented in three dimensions can be presented to the viewer. In one technique of presenting stereoscopic video, a viewer wears glasses having special optical characteristics, and presents an image with parallax between left and right eyes. For example, a time-division stereoscopic video display system includes a combination of a display device that displays a plurality of different videos in a time-division manner and shutter glasses worn by a v...
