<p>PURPOSE:To reduce fog in a reproduced picture by providing a 3rd reproduction means applying only an inter-field interpolation to an input signal and selecting the reproduced signal from the 3rd reproduction means when a frequency of the movement of a picture element being an object of reproduction in timewise direction is nearly intermediate. CONSTITUTION:An output signal of an input block 43 in an added block 47 is fed to an inter-field interpolation block 55. The interpolation block 55 adds input signals in terms of fields and the added signal is interpolated by a filter. Thus, an intermediate picture signal whose horizontal frequency is 32MHz is reproduced. The intermediate picture signal is fed to one input port of a multiplier 56 and the output signal of the multiplier 56 is fed to other input port of an adder 54. When the processing for the intermediate picture signal of the inter-field interpolation block 55 is applied, deterioration in picture quality to some degree is generated. However, so-called excellent picture quality with less fog is obtained entirely.</p> |
