Abstract
The motion signal detection method achieves splendid motion signal detection both from a video signal having an inter-frame difference signal of the same level as noise and a video signal obtained when a fine-patterned object moves in parallel translation. A video signal processing apparatus is provided for use with the above-mentioned motion signal detection method. The inter-frame difference signal obtained by a subtractor is input to the space expander circuit and then to a weighting coefficient generating circuit to obtain a weighting coefficient, and on the other hand, the inter-frame difference signal is input to an absolute value calculating circuit and a low pass filter, and the output signal is digitized by a quantizing circuit by using a quantizing parameter, which is controlled by the weighting coefficient.
