ABSTRACT:
A graphics controller circuit for upscaling source video image to generate an upscaled video image. The graphics controller circuit generates additional pixel data for the upscaled video image by interpolating source video pixel data of a one scan line and an another scan line. However, when source video pixel data of the another scan line may not be available for interpolation, the graphics controller circuit generates additional pixel data from source video pixel data of only the one scan line. Source video pixel data of the another scan line may not be available, for example, as a bus that transfers the pixel data may not have sufficient amount of bandwidth.
