<p>A method and apparatus for implementing a new imaging composition system based on the real world metaphor of surface absorption (a(1), a(2)), reflection (r(1), r(2)), and transmission (t(1), t(2)) where many layers of translucent and opaque objects (Object A, Object B) are composed into a final image for output to a video display (SEGMENT OF IMAGE DISPLAY). This system is based on a light propagation metaphor that uses virtual light source illumination (L) and the absorption (a(1), a(2)), reflection (r(1), r(2)), and transmission (t(1), t(2)) properties of the objects (Object A, Object B) in the image to create the final screen image (SEGMENT OF DISPLAY). Thus, instead of representing each picture element, or pixel, by color components specified by a chosen color model, e.g., RGB, YUV, Lab, HSV, YIQ, HLS, CMY, CMYK, etc., the pixels in the subject system are represented by six explicit transformation components r1, r2, r3, t1, t2, t3, and three implicit transformation components a1, a2, a3, wherein a, r, and t refer to absorption, reflection and transmission, respectively, and the subscripts 1, 2, and 3 refer to the components of the chosen color model.</p> |
