Patent ID: 7755700

Claim:
A motion-adaptive non-interlace conversion apparatus comprising: an interference elimination process circuit which executes a cross-color & dot interference elimination process; an intra-field interpolation process circuit which receives a processed signal from the interference elimination process circuit with a delay corresponding to 1 field, and generates an intra-field interpolation signal using the received processed signal; an inter-field interpolation process circuit which generates an inter-field interpolation signal by using two inter-field signals of the processed signal and a pre-process signal which is yet to be subjected to the cross-color & dot interference elimination process; a motion detection circuit which detects image motion and obtains a motion detection signal by using the two inter-field signals of the processed signal and the pre-process signal which is yet to be subjected to the cross-color & dot interference elimination process; a mixing circuit which mixes the intra-field interpolation signal and the inter-field interpolation signal with a mixing ratio corresponding to the motion detection signal and outputs a mixed signal; and a multiple-speed conversion circuit which executes a multiple-speed conversion process of an image signal by using the mixed signal from the mixing circuit and the processed signal that is output from the interference elimination process circuit with the delay corresponding to 1 field.
