It is considered that a method of comparing color signals from a color T. V. camera is one of effective methods in case of discriminating fruits from other materials such as leaves and stems by a visual sensor.
In this report, a visual sensor which vas composed of an area type image sensor, R, G, B filters, T. V. camera lens and so on was made as a trial, and we experimented on the discrimination of fruits from their leaves by use of two of R, G, B filters in order to examine the distribution of color component ratio of each fruit and its leaves and to obtain the most adequate pair of filters for the discrimination. In this experiment, tomatoes, eggplants, cucumbers, sweet peppers, mandarin oranges, persimon and their leaves were used as discriminated objects.
