Abstract
A method for scaling an image frame by an off-screen technology is provided. An image frame consisting of n rows and m columns of data is stored into a storage device. The image frame is divided into a plurality of image portions. Then, the plurality of image portions are picked in sequence to a frame buffer register. An image scaling operation is performed for each picked image portion, and then the scaled image portion is cleared from the frame buffer register.
