ABSTRACT:
A graphics image is produced for a computer display with depth of field information by producing a sharp image of a scene, producing a blur image of the scene, and producing z-buffer image data, and producing an alpha channel RGBA image comprising an alpha blend of the sharp and blur images with the z-buffer data. The alpha channel RGBA image thereby provides an image having depth of field information when reproduced on a computer display device.
