Abstract:
An image signal processing apparatus comprising:first de-interlace means for receiving interlaced scanning line signals of consecutive odd- and even-numbered fields by storage means and alternately reading out the scanning line signals of the consecutive odd- and even-numbered fields in units of scanning lines to perform de-interlacing; second de-interlace means for reading out the scanning line signals in the odd- or even-numbered field in units of fields and performing magnification processing in a vertical direction to perform de-interlacing; means for magnifying a non-interlaced signal obtained by said first and second de-interlace means, wherein said magnification means performs filter calculation for linear interpolation using at least two adjacent scanning line signals of the non-interlaced signal to perform magnification processing; and display control means for determining whether an input-image is a movie or a still image, when it is determined that the input-image is a still image, displaying the input-image on display means using a non-interlaced signal obtained by said first de-interlace means, and when it is determined that the input-image is a movie, displaying the input-image on said display means using a non-interlaced signal obtained by said second de-interlace means.
