DISPLAY DEVICE, GREYSCALE CORRECTION DEVICE, GREYSCALE CORRECTION METHOD, AND GREYSCALE CORRECTION PROGRAM

摘要

The present invention is equipped with a display unit (501), a light irradiation unit (502), a drive unit (503), a brightness detection unit (504), a greyscale correction unit (505), and a correction value calculation unit (506). The display unit (501) displays images. The light irradiation unit (502) irradiates the display unit (501) with light. The drive unit (503) drives the light irradiation unit (502) at a fixed value. The brightness detection unit (504) detects the brightness of the display unit (501). The greyscale correction unit (505) corrects the greyscale characteristic of an input video signal. The correction value calculation unit (506) calculates the greyscale correction characteristic on the basis of the detection value of the brightness detected by the brightness detection unit (504), and sets the greyscale correction characteristic in the greyscale correction unit (505).
