description PURPOSE:To obtain an accurate picture signal to be evaluated with high precision by using an actual camera circuit in use as a peripheral circuit operating a test element. CONSTITUTION:A pickup device using a test element TD actually, that is, a mount camera member SVB or a drive circuit and amplifier circuit having the equivalent performance are in use to output a video signal and the video signal from the amplifier circuit is converted into a signal attaining the check processing. Then a camera automatic adjusting device CC and a color separator CS are provided. Thus, since a wiring supplying a signal such as a drive signal to the test element TD from a part other than a picture process section VPU is not provided, the invasion of noise to the test element TD is avoided and the arithmetic coefficient for signal processing and the characteristic of the amplifier are matched substantially to the image pickup device in operation and an accurate picture signal with high precision is obtained.
