ABSTRACT:
Signal processing device for providing multiple output images by processing input images of an interlaced video signal, comprising a temporal interpolater circuit (18) and a memory buffer (26, 27) connected to the temporal interpolater circuit. The memory buffer (26, 27)is arranged for storing at least part of a previous input image (11, 13) and a current input image (12). The temporal interpolater circuit (18) is arranged for receiving at least the previous and current input image from the memory buffer (26, 27) and for providing multiple interlaced or de-interlaced frame data (15) at temporal positions between the previous input image temporal position and the current input image temporal position.
