Abstract

PURPOSE: To determine an exact photographic state even to an object of complicated and separated pattern and to measure the dimension of the object surely by displaying an ineffective and effective ranges of the sampling of the photographic object picture by means of a measurement limit line.
CONSTITUTION: The object 4 on a plane that is perpendicular to the photographic optical axis of the lens 2 of the TV camera 1 is photographed, its output signal is processed by the camera controller 5 to give itself to the dimension measuring unit 6, the cursor signal composed with the picture signal is fed to the display unit 7. In this case, the rotation controller 41 is controlled by an output of the camera controller 5, the turning mechanism 11 of the camera 1 is driven by an output of the controller 41. By operating the resistance RV11 of the controller 41, the sampling along the bright lines 13A, 13B in the left range of the measurement limit line 42 in the picture field is made ineffective and the one only in the right range of the line 42 is made effective, the outside of the photographic object picture 31A is surely made parallel to the cursor lines 10A, 10B.
