A first conductive contact connecting a first electrode of an inspection circuit board and one external electrode of a semiconductor integrated circuit is arranged in a fixed member. A second conductive contact connecting a second electrode of a wiring board and the other external electrode of the semiconductor integrated circuit is arranged in a movable member. A third conductive contact connecting one third electrode of the inspection circuit board and the other third electrode of the wiring board is arranged in the movable member. The other third electrode is connected to the second electrode. When the movable member moves to the contacting position, the second conductive contact makes contact with the other external electrode, and the third conductive contact makes contact with the one third electrode.

A phase control circuit sets the phase of a sampling clock signal for A/D conversion of a video signal in order. A binarizing circuit binarizes an analog video signal. A first counter circuit counts the changes of the output signal of the binarizing circuit. An A/D converting circuit digitizes the input signal. A second counter circuit counts the changes of the most significant bit of the A/D converting circuit. A subtracting circuit subtracts one from the other of the output signals of the two counter circuits. By changing the phase of the sampling clock signal of the A/D conversion in order within one period, the subtraction results are found, and this process is repeated for one or more periods. Thus the phase of the optimum sampling clock is set according to the subtraction results.

In a noise reducer whose S/N improving amount is variable, as to such a region where image quality deterioration caused by the noise reducer becomes relatively apparent, and both a luminance level and a chroma level are low, the S/N improving amount thereof is decreased. To the contrary, as to such a picture having a dark high frequency range component and a small movement component, no control is made of the S/N improving amount by the above-described luminance level and chroma level, but the normal S/N improvement is sufficiently carried out.

A contour restoration apparatus has a plurality of delay circuits connected in series. Maximum and minimum value detection circuits detect maximum and minimum values among an input video signal and output signals of the delay circuits. A mean value circuit is used to calculate a mean value of the of the maximum and minimum values. The mean value is subtracted from a delayed signal having a delay time of one-half of a delay time obtained from all the delay circuits. An adder is used to add the result of the subtraction to the delayed signal. A non-linear processing circuit processes the output of said adder and the maximum and minimum values. The non-linear circuit outputs the output signal of the adder, if the output signal of said adder is between the maximum value and the minimum value. A contour extraction circuit multiplies a signal located centrally among the input video signal, the output signals and the signals located before and after the input signal with a predetermined coefficient. An adder adds the multiplied signals. Another adder adds the result of multiplied signal and the centrally located signal. A contour amplitude circuit detects a difference between the maximum and minimum values and outputs a coefficient determined according to the difference detected. A mixer mixes the output of the non-linear processing circuit and the output of the another adder.
