A graphics image (508) is produced for a computer display (1690) with depth of field information by producing (1702) a sharp image (502) of a scene, producing (1704) a blur image (504) of the scene, and producing (1706) z-buffer image data, and producing (1708) an alpha channel (1410) 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. <IMAGE> |
