Device and Method of Downscaling and Blending Two High Resolution Images
First Claim
1. A device for downscaling and blending of a high-resolution compressed background image comprising pixels and a high-resolution compressed bitmap image comprising pixels, comprising:
- means for downscaling the background image by a predetermined factor;
means for uncompressing the downscaled background image;
means for uncompressing the high-resolution bitmap image;
means for dividing the uncompressed high-resolution bitmap image into blocks of pixels, whereby the size of each block correspond to the size of each pixel of the downscaled background image; and
means for blending each of the blocks of the uncompressed high-resolution bitmap image with each of the pixels of the downscaled background image and thus producing a blended image.

Abstract
The present invention relates to the field of downscaling and blending of two high resolution images, and particularly to a device and a method allowing for downscaling and blending of a HD JPEG background image and a HD bitmap image, which is overlaid on the JPEG background image. The device comprises means for downscaling the background image by a pre-determined factor n1, n2, . . . nN; means for uncompressing the downscaled background image and the high-resolution bitmap image; means for dividing the uncompressed high-resolution bitmap image into blocks of n1×n2× . . . ×nN pixels, whereby the size of each block correspond to the size of each pixel of the downscaled background image; and, means (16) for blending each of the blocks of the uncompressed high-resolution bitmap image with each of the pixels of the downscaled background image and thus producing a blended image.

7. A computer program, embodied in a computer-readable medium, for downscaling and blending a high-resolution compressed background image and a high-resolution compressed bitmap image, comprising:
-
downscaling the background image by a predetermined factor;
uncompressing the downscaled background image;
uncompressing the high-resolution bitmap image;
dividing the uncompressed high-resolution bitmap image into blocks of pixels, whereby the size of each block correspond to the size of each pixel of the downscaled background image; and
blending each of the blocks of the uncompressed high-resolution bitmap image with each of the pixels of the downscaled background image to produce a blended image.
