Abstract
A picture recording method for recording original picture data encodes the original picture so that the entirety of the original picture is displayed at its original resolution on a television monitor after being decoded. The method involves first scaling down an original picture image, then filling top, bottom, and left and right side regions around the scaled down picture image with pixels to attain a picture image that is of the same size and resolution as that of the original picture image. The scaled down and filled in image is then recorded by encoding and storing the picture data at the original resolution. The recorded picture data is then subsequently decoded for displaying all pixels of the original picture image at the original resolution on a television monitor.
