DISPLAY CONTROL APPARATUS AND METHOD OF DETERMINING DRIVING PARAMETER FOR OVERDRIVE
First Claim
1. A display control apparatus which determines a driving parameter for overdrive of a liquid crystal display device, the apparatus comprising:
- a first display unit which repeatedly scrolls a preset reference pattern image in a first region of the liquid crystal display device in one direction;
a second display unit which statically displays, in a second region of the liquid crystal display device, a plurality of sample images identical to the reference pattern image and having pseudo-afterimage regions whose end portions in a direction of the scrolling are different from each other;
a selection acceptance unit which accepts selection of one sample image of the plurality of sample images statically displayed in the second region from a user; and
a determination unit which determines the driving parameter for overdrive based on a difference between a pixel value of the pseudo-afterimage region of a selected sample image and a pixel value of a region corresponding to the pseudo-afterimage region of the reference pattern image.

Abstract
In order to allow a user to more easily set a correction amount in overdrive (OD) driving of a liquid crystal display device, a display control apparatus which determines a driving parameter for overdrive of the liquid crystal display device includes a first display unit which repeatedly scrolls a preset reference pattern image in one direction, a second display unit which statically displays a plurality of sample images identical to the reference pattern image and having pseudo-afterimage regions whose end portions in a scroll direction are different from each other, a selection acceptance unit which accepts selection of one sample image of the plurality of sample images, and a determination unit which determines the driving parameter for overdrive based on the difference between the pixel value of the pseudo-afterimage region of a selected sample image and the pixel value of the reference pattern image.

4. A display control apparatus which determines a driving parameter for overdrive of a liquid crystal display device, the apparatus comprising:
-
a first display unit which repeatedly scrolls a preset reference pattern image in a first region of the liquid crystal display device in one direction; a second display unit which statically displays, in a second region of the liquid crystal display device, a sample image identical to the reference pattern image and having a pseudo-afterimage region whose end portion in a direction of the scrolling changes in accordance with user operation using an operation unit; a selection acceptance unit which accepts, from a user, selection of one sample image of the plurality of sample images statically displayed in the second region; and a determination unit which determines the driving parameter for overdrive based on a difference between a pixel value of the pseudo-afterimage region of a sample image adjusted by a user and a pixel value of a region corresponding to the pseudo-afterimage region of the reference pattern image.

5. A method of determining a driving parameter for overdrive of a liquid crystal display device, the method comprising:
-
a first display step of repeatedly scrolling a preset reference pattern image in a first region of the liquid crystal display device in one direction; a second display step of statically displaying, in a second region of the liquid crystal display device, a plurality of sample images identical to the reference pattern image and sample images having pseudo-afterimage regions whose end portions in a direction of the scrolling are different from each other; a selection acceptance step of accepting selection of one sample image of the plurality of sample images statically displayed in the second region from a user; and a determination step of determining the driving parameter for overdrive based on a difference between a pixel value of the pseudo-afterimage region of a selected sample image and a pixel value of a region corresponding to the pseudo-afterimage region of the reference pattern image.
