摘要： An image signal processing apparatus is provided which is applicable to a motion adaptive Y/C separation of an NTSC signal and a time-domain/spatial interpolation of a high definition television signal band-compressed by sub-Nyquist sub-sampling. The apparatus includes a still image processing circuit having frame memories, a motion image processing circuit having a line memory, a mixing circuit for mixing outputs of these processing circuits, a circuit for detecting image motion of an input image signal and applying a resultant control signal to the mixing circuit, and a signal mode control circuit for selectively adapting the image processing circuits for the processing of the NTSC signal or the high definition television signal. The motion detecting circuit includes a narrow band detecting circuit for producing a one-frame interval difference signal of a signal spectrum of a pure low frequency component from the NTSC signal or the high definition television signal respectively, a wide band detecting circuit for a two-frame interval difference signal and a composition circuit for composing outputs of these detecting circuits. The still image processing circuit, motion image processing circuit and mixing circuit are adapted to operate for the Y/C separation with the NTSC signal and for the interpolation of the high definition television signal, respectively.

摘要： 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.

摘要： 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.

摘要： 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.
