No. 8,373,726, and contains subject matter related to Japanese Patent Application JP 2006-127090 filed in the Japanese Patent Office on Apr. 28, 2006, the entire contents of which being incorporated herein by reference.
FIGS. 3A, 3B, and 3C are diagrams for explaining operation for varying a light-on period;
FIGS. 4A and 4B are diagrams for explaining operation for controlling a supply voltage;
The highlighting degree controller 701 executes processing for determining the degree of increase in the maximum luminance based on a highlighting degree control signal supplied from the external, and processing for determining the degree of gamma conversion by the image quality converter 703.
The highlighting degree control signal indicates the degree of highlighting of a character part and is specified in linkage with displayed content of an application program.
The other determination criterion “grayscale difference with respect to the previous pixel in the determination order” is used in order to detect an edge between a background part and a character part. The number of kinds of edge is two: a start edge and an end edge. In this embodiment, the condition relating to the grayscale difference used for detection of a start edge is defined as “+Y or more”. Furthermore, the condition relating to the grayscale difference used for detection of an end edge is defined as “±1 or more”.
In the case of a liquid crystal display, the panel driver 5 executes control operation for increasing the light amount of a backlight light source based on a highlighting degree control signal.
