ABSTRACT:
The invention provides a device which converts an image from a first image format to a second image format in real time. A stream of image data in the first image format is processed by a horizontal filter to convert a horizontal resolution of the image to the horizontal resolution of the second image format. After such processing, the horizontal filtered data is buffered by a plurality of frame buffers in a controlled timing sequence to convert a frame rate of the image to the frame rate of the second image format. After such processing, the buffered data is processed by a vertical filter to convert a vertical resolution of the image to the vertical resolution of the second image format.
