Due 5:00 PM Wednesday, 2/10/99 EE 695A Homework No. 1 Spring 1998 1. Consider a trichromatic sensor with the sensor response functions shown below: 0.5 1.0 0.4 0.6 0.7 μ m 0.5 1.0 0.4 0.6 0.7 μ m 0.5 1.0 0.4 0.6 0.7 μ m V B ( λ ) V G ( λ ) V R ( λ ) a. Find the response (tristimulus vector) of this sensor to the stimulus S ( λ ) plotted below: 0.5 1.0 0.4 0.6 0.7 μ m S( λ ) b. Determine the amounts of each of three monochromatic primaries D R ( λ ) = δ ( λ - 0.65) , D G ( λ ) ( λ- 0.525) , D B ( λ ) = δ ( λ - 0.45)required to match this stimulus. Is a direct match possible? 2. In class we defined the chromaticity diagram or Maxwell’s triangle, as the plane that intersects a 3-D coordinate system, say RGB at the points (1,0.0), (0,1,0), and (0,0,1). The coordinate axes need not be perpendicular. The triangle formed by three lines connecting these points is what we plot as the chromaticity diagram. a.
