  • Method and apparatus for image display processing that reduces CPU image scaling processing
    Patent number: 6417866
    Abstract: From a display memory, an image scaler retrieves display data representing an image, and produces a data stream representing a scaled version of the image. Based on the data stream, a digital-to-analog converter produces display signals suitable for displaying the scaled version on as a full-screen image on a display screen. Optionally, the scaled version is displayed in a window on the display screen. Characteristics of the scaled version are based on input signals intercepted from a keyboard and a pointing device by an input interception program. For a pointer displayed on the display screen for the pointing device, logical and visual pointer positions are determined based on the input signals and the characteristics of the scaled version.
