Abstract
In an image signal converter (ICp ) converting a component video signal (Scv) of an interlaced scanning format for image display on a display device for an image signal of a progressive scanning format (Scv, p) for image display on the display device, an up-converter ( ) converts the component video signal (Scv) of the interlaced scanning format into the one of the progressive scanning format. A scanning format determination part ( ) determines based on a luminance signal (Y) included in the component video signal (Scv , Scv ) whether the component video signal (Scv , Scv ) is of the interlaced or progressive scanning format. Based on the determination result of the scanning format determination part ( ), an output destination selector ( B, A) selects an output destination of the component video signal (Scv , Scv ). When the scanning format determination part ( ) determines that the format is the interlaced scanning format, the component video signal (Scv , Scv ) is supplied to the up-converter ( ).
