Abstract
In a slow motion video generation apparatus; successive fields of an input video signal are stored in field stores, a spatial interpolator spatially interpolates between lines of a field selected from those stored in the field stores to produce a spatially interpolated video signal, a temporal filter carries out temporal interpolation between a pair of fields of the same interlace polarity selected from those stored in the field stores to produce a temporally filtered video signal, a combining device selectively receives the spatially and temporally interpolated video signals, and a movement indicator compares the fields stored in the field stores to detect whether or not there is local movement in the picture represented by the stored fields and controls the combining device so that the output signal is substantially wholly constituted by the temporally interpolated video signal in picture areas where substantially no movement is detected and is substantially wholly constituted by the spatially interpolated video signal in picture areas where more than a predetermined amount of movement is detected.
