Abstract
An image display apparatus of the present invention includes: a picture display unit that forms and displays an optical image based on a video signal; a gamma adjustment image display unit that displays a gamma adjustment image containing input/output characteristics of a signal level of the video signal in the displayed optical image; an adjustment operation unit that changes the displayed input/output characteristics on the image; and an input/output characteristics setting unit that sets input/output characteristics of the signal level of the video signal in accordance with the input/output characteristics changed on the image. The adjustment operation unit includes a point selecting part that selects an adjustment point desired to be changed in the input/output characteristics displayed in the image and a level changing part that is capable of changing both of an input level and an output level of the selected adjustment point. Because both of an input signal level and an optical output level can be adjusted, a user can make gamma adjustment easily, freely, and in detail.
