Abstract:
1. An image signal processing device comprising: a determination section performing determination, for each of fields, on a first input image signal as an interlaced signal or a second input image signal as an interlaced signal having horizontal parallax to the first input image signal or both thereof, the determination being concerned with whether an input image signal is an interlaced signal derived from video signal or from pulldown-converted film signal; deinterlace sections performing deinterlace, for each of fields, on each of the first and second input image signals, through use of interpolation for a video signal or pull down reverse conversion for a film signal, thereby generating a first output image signal as a progressive signal and a second output image signal as a progressive signal having horizontal parallax to the first output image signal; and a synchronous control section performing synchronous control to the deinterlace sections, based on a determination result of the determination section, such that deinterlace applied to the first input image signal and deinterlace applied to the second input image signal, synchronized with each other for each of fields, are of same type, wherein the determination section provides a first indication indicating whether the first input image signal is an interlaced signal derived from video signal or from pulldown-converted film signal, and a second indication indicating whether the second input image signal is an interlaced signal derived from video signal or from pulldown-converted film signal, and wherein a comparison is made between the first indication and second indication, and the deinterlace applied to the first input image signal and the second input image signal is based on the comparison.
