Display method, display controller, and display apparatus
First Claim
1. A display method for use with a light source and a display device operable to display pictures in accordance with a video signal, said method comprising:
- displaying pictures on the display device according to a display timing;
illuminating the display device with light from the light source in response to a light source-controlling signal;
changing an amount of light emitted from the light source according to a light-change timing; and
synchronizing the display timing with the light-change timing.

Abstract
A display controller including a video signal-analyzing unit, a video signal-adjusting unit operable to receive a video signal, to adjust the video signal in accordance with adjustment parameter information, and to feed the adjusted video signal into a display device, and a light source-controlling unit operable to feed a light source-controlling signal into a light source in accordance with light source light-emitting amount information. The video signal-analyzing unit allows timing in which the display device displays a picture in accordance with the adjusted video signal from the video signal-adjusting unit to be synchronized with timing in which the light source changes a light-emitting amount in response to the light source-controlling signal from the light source-controlling unit. As a result, such two different timings are held in a proper relationship with one another, and degradation in image quality is suppressed, which otherwise would result from a change in the light source to become dark and bright. This feature realizes high-quality video display.

7. A display controller for use with a display device and a light source, said display controller comprising:
-
a video signal-analyzing unit operable to receive and analyze a video signal, and to generate adjustment parameter information and light source light-emitting amount information;
a video signal-adjusting unit operable to receive the video signal, adjust the video signal in accordance with the adjustment parameter information from said video signal-analyzing unit, and to feed the adjusted video signal into the display device; and
a light source-controlling unit operable to feed a light source-controlling signal into the light source in accordance with the light source light-emitting amount information from said video signal-analyzing unit, wherein said video signal-analyzing unit synchronizes a timing at which the display device is to display a picture based on the adjusted video signal from said video signal-adjusting unit, with a timing at which the light source is to change a light-emitting amount in response to the light source-controlling signal from said light source-controlling unit. - View Dependent Claims (8, 9, 10, 11)

12. A display apparatus comprising:
-
a display device;
a light source; and
a display controller comprising;
a video signal-analyzing unit operable to receive and analyze a video signal, and to generate adjustment parameter information and light source light-emitting amount information;
a video signal-adjusting unit operable to receive the video signal, adjust the video signal in accordance with the adjustment parameter information from said video signal-analyzing unit, and to feed the adjusted video signal into said display device; and
a light source-controlling unit operable to feed a light source-controlling signal into said light source in accordance with the light source light-emitting amount information from said video signal-analyzing unit, wherein said video signal-analyzing unit synchronizes a timing at which said display device displays a picture based on the adjusted video signal from said video signal-adjusting unit, with a timing at which said light source changes a light-emitting amount in response to the light source-controlling signal from said light source-controlling unit;
wherein said display device is operable to display a picture in accordance with the adjusted video signal that is fed from said video signal-adjusting unit of said display controller; and
wherein said light source is operable to illuminate said display device with light in accordance with the light source-controlling signal that is fed from said light source-controlling unit of said display controller. - View Dependent Claims (13, 14, 15, 16)
