Abstract:
1. An image processing apparatus for converting an image of an interlacing system into an image of a progressive system, said image processing apparatus comprising: an inter-field interpolating means for interpolating a pixel of said image of the progressive system using a pixel of a field of said image of the interlacing system to be converted and a pixel of a different field; an intra-field interpolating means for interpolating a pixel of said image of the progressive system using pixels within the field of said image of the interlacing system to be converted; a determining means for determining whether a pixel to be interpolated of said image of the progressive system is a moving image pixel or a still image pixel; and a selecting means for selecting either said pixel interpolated by said intra-field interpolating means or said pixel interpolated by said inter-field interpolating means on the basis of a result of the determination by said determining means; wherein said determining means determines that said pixel to be interpolated of said image of the progressive system is a moving image pixel based at least in part on the absolute values of at least one of intra-field temporal differences and inter-field temporal differences.
