Abstract
An image display device includes a total luminance value detection portion that detects a total luminance value in an entire image; a level detection portion that detects whether the total luminance value exceeds a specific level; and an incident light level lowering processing portion that performs processing to reduce an illumination light quantity from a light source that goes incident on a light modulation element in accordance with a function of the total luminance value when the level detection portion detects that the total luminance value exceeds the specific level.
Claims7
An image display device, comprising:
- a total luminance value detection portion that detects a total luminance value in an entire image;
- a level detection portion that detects whether the total luminance value exceeds a first specific level;
- and
- an incident light level lowering processing portion that performs processing to reduce an illumination light quantity from a light source that goes incident on a light modulation element in accordance with a function of the total luminance value when the level detection portion detects that the total luminance value exceeds the first specific level.
An image display method, comprising:
- detecting a total luminance value of an entire image;
- detecting whether the total luminance value exceeds a specific level;
- and
- reducing an illumination light quantity from a light source by performing light control in accordance with a function of the total luminance value when it is detected that the total luminance value exceeds the specific level.
A program causing a computer inside an image display device to function as:
- a total luminance value detection portion that detects a total luminance value in an entire image;
- a level detection portion that detects whether the total luminance value exceeds a specific level;
- and
- an incident light level lowering processing portion that performs processing to reduce an illumination light quantity from a light source that goes incident on a light modulation element in accordance with a function of the total luminance value when the level detection portion detects that the total luminance value exceeds the specific level.
