<P>PROBLEM TO BE SOLVED: To provide a technology of enhancing image quality in motion correcting image processing utilizing a motion vector by suppressing the distortion of an image generated by interpolation caused in the unit of a block and mismatching between a pixel generated by the interpolation and its surrounding pixels while reducing the cost of computational complexity. <P>SOLUTION: An inter-field interpolation space transition is obtained on the basis of difference absolute sums between an inter-field interpolation pixel Pt and a pixel B adjacent to the pixel Pt on the same field and between the inter-field interpolation pixel Pt and a pixel D adjacent to the pixel Pt on the same field. An inter-field interpolation time transition is obtained on the basis of difference absolute sums between the inter-field interpolation pixel Pt and a pixel A at the same position in a preceding delayed field and between the inter-field interpolation pixel Pt and a pixel C at the same position in a present field. An in-field interpolation time transition is obtained on the basis of difference absolute sums between an in-field interpolation pixel Ps and the pixel A at the same position in the preceding delayed field and between the in-field interpolation pixel Ps and the pixel C at the same position in the present field. An amount of errors produced in pixels generated by the interpolation is obtained on the basis of the information of the inter-field interpolation space transition, the inter-field interpolation time transition, and the in-field interpolation time transition, and the inter-field interpolation or the in-field interpolation is selected depending on the amount of generated errors to generate pixels. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
