Patent ID: 11962951
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 9:
10. An image processing system comprising:
an image signal processor configured to process first image data for pixel data in a graphic image and second image data for pixel data in a video image to generate an output image;
a memory configured to receive first compressed data for the first image data, second compressed data for the second image data, and the output image; and
a display configured to display the output image,
wherein the image signal processor includes:
a first encoder configured to receive the first image data and perform compression on the first image data to generate the first compressed data;
an alpha map scaler configured to extract an alpha value α of the graphic image from the first image data and generate an alpha map for the alpha value α; and
a second encoder connected to the memory and configured to:
receive the alpha map and the second image data;
perform computation on the second image data using the alpha map to generate multiply data;
perform compression on the multiply data to generate second compressed data; and
store the second compressed data in the memory.
