Abstract
A method and apparatus for generating a composite image from multiple source images using multiple local masks. Each source image is generated by an image generator. Each image generator has a local mask that indicates which pixels of the source image are to be transmitted to a frame buffer. The local mask may also be used to indicate which pixels of the source image are to be updated by the image generator.
Claims28
A method for generating composite images, comprising the steps of:
- (a) generating data of a first source image with a first image generator;
- (b) generating data of a second source image with a second image generator;
- (c) transmitting data of said first source image to a frame buffer in accordance with a first mask;
- and
- (d) transmitting data of said second source image to said frame buffer in accordance with a second mask, wherein:
- said first source image comprises a plurality of first-image pixels;
- said second source image comprises a plurality of second-image pixels;
- said first mask comprises a plurality of first-mask pixels, each of said first-mask pixels having a corresponding value and each of said first-mask pixels corresponding to one of said first-image pixels;
- said second mask comprises a plurality of second-mask pixels, each of said second-mask pixels having a corresponding value and each of said second-mask pixels corresponding to one of said second-image pixels;
- step (c) comprises the step of transmitting each of said first-image pixels having a corresponding first-mask pixel of non-zero value;
- and step (d) comprises the step of transmitting each of said second-image pixels having a corresponding second-mask pixel of non-zero value.
