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.
