1. A method of displaying image data, comprising the steps of:
- analyzing histograms of color signals of an input image frame;
confirming grayscales of the color signals in a predetermined frame unit with reference to the analyzed histograms;
determining dimming factors based on maximum grayscale values of the grayscales;
determining image gains of the image data of the color signals using the determined dimming factors; and
outputting an image signal by applying the image gains and the dimming factors to the input image.

Abstract
A method of displaying image data is provided, which includes analyzing histograms by color signals of an input image frame; confirming grayscales by color signals in a predetermined frame unit with reference to the analyzed histograms; determining dimming factors in consideration of maximum grayscale values of the grayscales; determining image gains of the image data by color signals using the determined dimming factors; and outputting an image signal by applying the image gains to the input image and applying the dimming factors to a light source.

7. A display apparatus, comprising:
-
a light source unit providing light required to drive a display device; a light source driving unit providing driving signals to the light source unit; an image conversion unit converting image data into color signals of a predetermined format; a display panel controlling grayscales of respective pixels constituting the image data; a panel driving unit supplying driving signals to the display panel; and a control unit confirming dimming factors of the color signals of image frames by analyzing histograms of the color signals of the respective image frames, outputting signals for controlling the brightness of the light source to the light source driving unit through reflection of the dimming factors, setting image data gains of the color signals based on the dimming factors, and providing the color signals in which the gains are reflected to the panel driving unit. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
