| (in English) | Abstract It is well known that tree types of cones and opponent color channels exist in the our color vision system. Recently, it was suggested that multiple chromatic channels existed in higher level. However their precise features are not yet obvious. Our purpose is to reveal these features of the multiple chromatic channels by comparing results of dichoptic chromatic-masking with those of monocular chromatic-masking. A target stimulus was Gabor modulated along the r/g axis. A mask stimulus consisted of random dots modulated varied color directions. Results of dichoptic masking suggest that the direction slightly tilted to y/b axis is independent of r/g axis. Results of monocular masking could not be compared with those of dichoptic masking because effects of monocular masking are weak. | |
