Abstract
A display apparatus includes a luminance controller that controls a luminance of a displayed video, a gamma controller that applies a gamma curve to a video signal, and a display that displays a video represented by the video signal that the gamma controller has applied the gamma curve to. If the luminance controller causes the display to display the video at a luminance value lower than a predetermined luminance value, the gamma controller applies to the video signal a gamma curve with a lower gradation region raised more than a gamma curve represented by a predetermined constant gamma coefficient.
