Image signal processing device, three-dimensional image display device, three-dimensional image transmission/display system, and image signal processing method

摘要

An image signal processing device improving quality of three-dimensional image is provided. The device includes a determination section (42L, 42R), deinterlace sections (44L, 44R) and a synchronous control section (43). The determination section (42L, 42R) determines whether first and/or second input image signals (D1Li, D1Ri), having horizontal parallax therebetween, are interlaced signals derived from video signal or from pulldown-converted film signal. The deinterlace sections (44L, 44R) perform deinterlace on each of the first and second input image signals (D1Li, D1Ri), through interpolation for a video signal or pulldown reverse conversion for a film signal, and generate first and second output image signals (D2Lp, D2Rp) as progressive signals, having horizontal parallax therebetween. The synchronous control section (43) synchronously controls the deinterlace, based on result of the determination section (42L, 42R), such that deinterlace process onto the first and second input image signals (D1Li, D1Ri), synchronized with each other for each of fields, are of same type.
