Method and apparatus for upscaling an image |
摘要 |
An upscaler for upscaling a source image to generate a destination image without requiring large buffers. The aspect ratio (ratio of the length of the source image to that of the width) of the source image need not equal the aspect ratio of the destination 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 using only a line buffer.
