Abstract: A motion estimation apparatus and method are disclosed. The motion estimation apparatus includes processing element (PE) array units, sub-SAD calculation units, motion vector calculation units, and a minimum motion vector selector. The PE array units each perform parallel processing for each of the three types of coding units. The sub-SAD calculation units calculate respective SAD values for the three types of coding units. The motion vector calculation units calculate respective motion vectors for the three types of coding units. The minimum motion vector selector selects a minimum motion vector from among the motion vectors.

Abstract: An apparatus and method for skipping fractional motion estimation (FME) in high efficiency video coding (HEVC) are disclosed. The apparatus includes a current sum of absolute differences (SAD) acquisition unit, a redundancy determination unit, and a motion estimation skip unit. The SAD acquisition unit acquires the SAD from an integer motion estimation (IME) unit when the IME unit performs IME on a coding tree block (CTB). The redundancy determination unit determines whether or not the CTB is an estimated redundant block using the current SAD. The motion estimation skip unit provides an FME unit with an FME skip signal of the CTB depending on whether or the CTB is an estimated redundant block.
