IMAGE DISPLAY APPARATUS AND METHOD
First Claim
1. An image display apparatus, comprising:
- an input unit which sequentially inputs frame images that form a moving image;
a subframe image generation unit which generates a subframe image to be displayed at timing between display timings of two adjacent frame images;
a display frame image generation unit which generates a display frame image, in which a pixel being at a pixel position closer to a periphery of the frame image has smaller luminance value than that of a pixel being at a center of the frame image;
a display subframe image generation unit which generates a display subframe image, in which a pixel being at a pixel position closer to a periphery of the frame image has larger luminance value than that of a pixel being at a center of the frame image; and
an output unit which sequentially outputs the display frame image and the display subframe image.

Abstract
The image signal of each pixel of a frame image is multiplied by a gain value set in advance for each coordinate position on a display screen, generating a display frame image in which the luminance value becomes smaller for a pixel closer to the periphery of the display screen and larger for a pixel closer to the center. The image signal of each pixel of a subframe image is multiplied by a gain value set in advance for each coordinate position on the display screen, generating a display subframe image in which the luminance value becomes larger for a pixel closer to the periphery of the display screen and smaller for a pixel closer to the center of the display screen. The display frame image and display subframe image are sequentially displayed.

6. An image display method performed by an image display apparatus having a display screen for displaying a moving image, comprising:
-
an input step of sequentially inputting frame images that form the moving image; a subframe image generation step of generating a subframe image to be displayed at timing between display timings of two adjacent frame images; a display frame image generation step of generating a display frame image, in which a pixel being at a pixel position closer to a periphery of the frame image has smaller luminance value than that of a pixel being at a center of the frame image; a display subframe image generation step of generating a display subframe image, in which a pixel being at a pixel position closer to a periphery of the frame image has larger luminance value than that of a pixel being at a center of the frame image; and an output step of sequentially outputting the display frame image and the display subframe image. - View Dependent Claims (7, 8, 9, 10)
