Embodiment Construction
[0030] The present invention will be described in detail below in conjunction with the drawings and embodiments.
[0031] As shown in Figure 1, the above formulas 1, 2 and 3 are modified, and the half-pixel level b corresponding to the whole pixel A can be expressed as:
[0032] b=(m+1-rounding_control) / 2 (4);
[0033] The horizontal half-pixel corresponding to the whole pixel C is e and can be expressed as:
[0034] e=(n+1-rounding_control) / 2 (5);
[0035] The diagonal half-pixel d corresponding to the whole pixel A can be expressed as:
[0036] d=(m+n+2-rounding_control) / 2 (6),
[0037] Among them: m=A+B, n=C+D.
[0038] When calculating b, d, and e by using the intermediate summation results m and n in the calculation process, the repeated calculation when generating d according to formula 3 is reduced.
[0039] As shown in Figure 2, in h.263 and mpeg4 part2, when using the unrestricted motion vector mode, the edge of the image needs to be expanded. For example, according to h....
