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