Abstract
Provided are a method and apparatus for displaying luminance. The method includes displaying luminance information corresponding to horizontal and vertical axes of an image. Accordingly, the total luminance of the image and luminance information on positions and regions of the image can be detected intuitively.
Claims20
A method of displaying luminance on a display screen, comprising:
- calculating luminance values of a horizontal axis and a vertical axis of an input image based on luminance components of the input image;
- generating histograms of the horizontal axis and the vertical axis according to the calculated luminance values of the horizontal axis and the vertical axis;
- and
- controlling the display screen to display the generated histograms of the horizontal axis and the vertical axis.
