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, in one direction, a preset reference pattern image in a first region of the liquid crystal display device;
a second display unit which statically displays, in a second region of the liquid crystal display device, a plurality of sample images each having a shape identical to the shape of the reference pattern image and having pseudo-afterimage regions at end portions in a direction of the scrolling, wherein brightness values of each pseudo-afterimage region are different from each other within a first predetermined brightness values range;
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,wherein, responsive to the selection acceptance unit accepting selection of one sample image, the second display unit statically displays a plurality of sample images each having a shape identical to the shape of the reference pattern image and having pseudo-afterimage regions at end portions in a direction of the scrolling, wherein brightness values of each pseudo-afterimage regions are different from each other within a second predetermined brightness values range that is narrower than the first predetermined brightness values range.

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 method of determining a driving parameter for overdrive of a liquid crystal display device, the method comprising:
-
a first display step of repeatedly scrolling, in one direction, a preset reference pattern image in a first region of the liquid crystal display device; a second display step of statically displaying, in a second region of the liquid crystal display device, a plurality of sample images each having a shape identical to the shape of the reference pattern image and sample images having pseudo-afterimage regions at end portions in a direction of the scrolling, wherein brightness values of each pseudo-afterimage region are different from each other within a first predetermined brightness values range; 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; and responsive to acceptance of a selection of one sample image in the selection acceptance step, a third display step of statically displaying a plurality of sample images, in substitution of the plurality of sample images displayed by the second display step, each having a shape identical to the shape of the reference pattern image and having pseudo-afterimage regions at brightness values of end portions in a direction of the scrolling, wherein brightness values of each pseudo-afterimage region are different from each other within a second predetermined brightness values range that is narrower than the first predetermined brightness values range.
