Abstract:
A video reproduction device includes a calibration image generator configured to generate calibration images to be displayed by a display and a display device; a receiver configured to receive, from an image capturing device, a captured image in which the calibration image displayed by the display and the calibration image displayed by the display device are captured or information generated on the basis of the captured image; a corrected data calculator configured to calculate color-component-corrected data from a color component difference between the calibration image displayed by the display and the calibration image displayed by the display device; and a second video signal output configured to perform color correction on a video signal representing the same video as the video signal that is output to the display according to the corrected data obtained by the corrected data calculator and output a color-corrected video signal to the display device.
