Abstract
An image interpolation method and apparatus are provided. The image interpolation method includes: selecting different interpolation filters according to locations of sub pixels between integer pixels; and generating sub pixel values at the locations of the sub pixels using the selected interpolation filters.
Claims15
An image interpolation method comprising:
- selecting an interpolation filter from among different interpolation filters according to locations of sub pixels between integer pixels;
- and
- generating sub pixel values at the locations of the sub pixels using the selected interpolation filters.
An image interpolation method comprising:
- setting interpolation filters having different characteristics to interpolate sub pixels between integer pixels according to a size of a block including the integer pixels and locations of the sub pixels;
- selecting an interpolation filter used to interpolate the sub pixels according to the size of the block and the locations of the sub pixels;
- and
- generating sub pixel values at the locations of the sub pixels using the selected interpolation filter.
