Abstract
An upscaler for upscaling a source image to generate a destination image without having to maintain the aspect ratio (ratio of the length of the source image to that of the width) of the source image. The source image pixel data is received at a first clock rate and the destination image is generated at a second clock rate. The second clock rate is computed such that the frame rate at which the source image is received is the same as the frame rate at which the upscaled image is generated. Because of such a clock rate, the upscaler may be implemented only a line buffer for upscaling a source image. Prior systems may require large memories such as frame buffers for achieving similar functionality.
