Abstract
PURPOSE:To detect the object with high precision and excellent response on discriminating the presence or absence of a singular point by analogly treating the video signal from the TV camera and performing the level collation with the fererence signal. CONSTITUTION:The video signal Vs from the TV camera 1 that photographs the object 2 is fed to the characteristic abstracting circuit 6, the output signal Sc of which is compard with the reference signal Sr in the comparator 8, whether the abstracted part is normal is discriminated by level collation, the decision signal Sd is available at the output as an abnormal point detection signal Dt through the trimming gate 9 and timing gate 10. On the other hand, the horizontal and vertical synchronizing signals Sh, Sv from the camera 1 are fed to the trimming circuit 11 and cursor sampling hold circuit 12. Outputs of the circuits 6, 11, 12, 13 are mixed in the mixer circuit 14, and provided to the monitor TV 16.
