ABSTRACT:
Inter-field-interpolation spatial transition is calculated based on the sum of absolute values of differences between pixel values of an inter-field-interpolated pixel and adjacent pixels on the same field. Inter-field-interpolation temporal transition is calculated based on the sum of absolute values of differences between pixel values of the inter-field-interpolated pixel and pixels at corresponding positions on previous delayed field and present field. Intra-field-interpolation temporal transition is calculated based on the sum of absolute values of differences between pixel values of an intra-field-interpolated pixel and the pixels at the corresponding positions on the previous delayed field and the present field. The amounts of error in the interpolated pixels are calculated based on information of the inter-field-interpolation spatial transition, inter-field-interpolation temporal transition, and intra-field-interpolation temporal transition, and a pixel is generated by switching between inter-field interpolation and intra-field interpolation accordingly.
