Title: Edge key generating method and edge key generating apparatus

Abstract: To enable interlacing edge-generating means to be used for a progressiveimage signal that is separated into lines as two sequences of signals, thepresent invention comprises a pre-edge processing circuit (11) thatexecutes appropriate pre-edge processing on the progressive image signalseparated into lines depending on the condition of each of the twosignals, and an edge generating circuit (18, 19) that executes on the twosignals after pre-edge processing pre-edge generation processing similarto that for interlacing.
