Abstract

There are two cone-opponent mechanisms, |M-L| and |L+M-S| cone-opponent mechanisms that contribute to red-green and blue-yellow perception, respectively. At a dim light level in mesopic vision, rods contribute color perception as well as cones. Here we have investigated a contribution of rod signals to the cone-opponent mechanisms. We used a four primary stimulation system that enables independent stimulation to each receptor to control stimulation of the three types of cones and rods. We applied these stimuli for a test stimulus at intense photopic light level and at dim mesopic light level. It was found that rods contribute to |M-L| cone-opponent color signals at the mesopic light level.
