Title: Detecting circuit for saturation of video signal
Inventor: KOBAYASHI KIYOHIKO
IPC: G01M11/02
Filed: 1982-02-09
Abstract: PURPOSE:To provide a means of eliminating a state of saturation by identifying the saturation from the frequency of continuation of video signal being continued at a fixed level as a condition captured with a saturation detecting circuit for video signal used for an MTF inspection machine. CONSTITUTION:When a CCD sensor 4 becomes saturated, video signals of the same level are outputted continuously above a certain level determined as a characteristic of the CCD sensor 4. In this condition, for example, the frequency of continuation of the video signals at the same level as mentioned above is detected. In other words, a condition in which video signals are continued at a fixed level is captured to detect that saturation is occuring or occured depending on the frequency of continuation and the result is transmitted to a system controller 15. Therefore, if the setting for the intensity of the light source, the exposure of a photoelectric conversion element, the charge accumulation time and the like as required for the MTF inspection are programmed into the system controller 15 in preparation of action when said saturation signal is received, an MTF inspector can always measure MTF up to the full dynamic  range of the photoelectric conversion element. This can improve the measuring  accuracy of the MTF inspector with a higher signal-noise ratio.
