Abstract

In the embodiment disclosed in the specification, a rangefinder comprises left and right sensor arrays for receiving the light of an image of an object, evaluative signal generating circuits for defining the interrelation between left and right image data trains representing the distribution of light intensity within the object, an optimum shift value decision circuit for determining the shift number in the image data train corresponding to the highest correlation between both the image data trains, a range signal computing circuit for computing a range signal representing the distance up to the object from the optimum shifted number, and a control circuit for controlling and regulating a predetermined portion in equipment utilizing the range signal. The evaluative signal generating circuits are arranged to generate the evaluative signals simultaneously and transmit them in parallel to the shift value circuit defining the correlation between the left and right image data trains. The evaluative signal generating circuits and the optimum shift value decision circuit are contained in a first circuit device, whereas the control circuit means are contained in a second circuit device. The first circuit device starts rangefinding operation on receiving instructions from the second circuit device and transmits the range signal to the second circuit device after determining the optimum shifted number.
