Display control apparatus and method and image processing method

摘要

A display control apparatus is capable of reducing image scaling times, maintaining image quality, and extending a turn-on time of a pair of 3D glasses. The display control apparatus includes a data processing unit and a timing generating unit. The data processing unit provides an image frame comprising a valid data region, which is larger than a visual region of a display panel. The timing generating unit generates an output timing signal according to a relative position of the visual region corresponding to the valid data region, so that a partial region of the valid data region corresponds to the visual region of the display panel. The partial region of the valid data region is displayed in the visual region of the display panel according to the output timing signal.

主权项

1. A display method, for displaying a frame on a display panel, comprising:
providing the frame comprising a valid data region that is larger than a visual region of the display panel, wherein a partial region of the valid data region corresponds to the entire visual region, and the partial region has a same number of scan lines as the visual region; generating an output timing signal according to a relative position of the visual region corresponding to the valid data region, such that said output timing signal corresponds to quantity of scan lines that only link to the partial region of the valid data region; outputting the frame and the output timing signal to the display panel so as to display the partial region of the valid data region in the visual region of the display panel according to the output timing signal; and providing a glasses control signal, so that a pair of 3D glasses is turned on during a scan interval corresponding to a remaining region of the valid data region excluding the partial region.
