Abstract:
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.
