Abstract (en)
[origin: EP0849631A1] A color filter (49, 55) has blue, green and red pixel patterns (50-52, 56-58) and a black matrix (53, 59). To produce the color filter from silver halide photosensitive film (10), an exposure mask (22, 83) is used. The exposure mask includes a first group (40, 90) of light-transmitting slits adapted to exposure of the blue pixel pattern. A second group (41, 91) of light-transmitting slits are adapted to exposure of the green pixel pattern. A third group (42, 92) of light-transmitting slits are adapted to exposure of the red pixel pattern. A fourth group (43, 93) of light-transmitting slits are adapted to exposure of the black matrix. First to third auxiliary filters (36, 45-47) respectively cover the first to third groups of the light-transmitting slits. <IMAGE>
