Abstract

PURPOSE: To decrease an influence of an outside light and reduce a quantity of irradiated light making a color temperature constant by providing a means for opening and closing light incident to a monitor camera and synchronizing an irradiation by an irradiating means with the opening and closing of light incident to the camera.
CONSTITUTION: A monitor camera 1 using a color video camera incorporating a shutter 2 is provided with a stroboscope 3 as an irradiating means and a shutter controller 4 for controlling a shutter speed. By a trigger signal TG of the stroboscope 3, an opening and a closing of the shutter 2 by the shutter controller 4 are synchronized, and by opening and closing the shutter 2 simultaneously with the irradiation by the stroboscope 3, a fruit of an object to be taken a picture can be taken a picture with a constant brightness. A color image signal for one frame taken a picture by the monitor camera 1 is converted into a binary signal corresponding only to the fruit by a color identifying device 5 and stored in a frame memory 6. The result is displayed by a monitor television 7, and at the same time, a processing such as a fruit position detection is done to obtain a fruit recognition device capable of automatically separating and discriminating from other objects.
