Abstract:
A picture encoding method comprising the steps of:scaling down an original unencoded picture image; filling top, bottom, and left and right side regions around the scaled down picture image with pixels having predetermined color information for attaining an original resolution of said original picture image; encoding said scaled down and filled in picture image as encoded picture data so that said original picture image is encoded at said original resolution; wherein the encoded picture data is displayed with all pixels of said original picture image at said original resolution on a television monitor; wherein said step of scaling down an original picture image scales down an uncoded picture image as said original picture image and wherein said encoding step includes encoding said scaled down and filled in picture image as encoded picture data; further comprising the step of scaling down said original picture image while satisfying the conditions of X=SXâˆ’(a1+a2) Y=SYâˆ’(b1+b2) where, X stands for a width of said scaled down picture image, Y for a height of said scaled down picture image, SX for a width of said original picture image yet to be scaled down, SY for a height of said original picture image, a1 for a width of a group of pixels filling the region on the left side of said scaled down picture image, a2 for a width of a group of pixels filling the region on the right side of said scaled down picture image, b1 for a height of a group of pixels filling the region on top of said scaled down picture image, b2 for a height of a group of pixels filling the region at the bottom of said scaled down picture image; andwherein a1, a2, b1 and b2 are any integers which are larger than 0 and which further satisfy the conditions of a1212
