装置。[Claims for Utility Model Registration] In a system that clamps the DC component of a video signal to a constant potential and then processes the video signal by converting it from analog to digital, a system that responds to a clamp pulse and responds to the DC component of the video signal. a data latch means for latching the output data of the analog-to-digital converter at a predetermined timing synchronized with a clock for analog-to-digital conversion; a comparison means for comparing the latched data with a reference value; and an output of the comparison means. A clamp level inspection device comprising: display means for displaying the comparison result based on a signal.
