Abstract (in Japanese) (See Japanese page) 
(in English) With the rapid progress of ultra-high definition videos represented by the 4K / 8K UHDTV and of complex video compression algorithms represented by the latest video coding standard HEVC, power consumption required for real-time video coding process is steadily increasing. In this paper, we focus on the motion estimation process of HEVC encoding for UHDTV, and propose a method which reduces SAD calculation bit width but also reduces picture quality degradation by adaptively switches bit reduction positions depending on the local flatness of encoding pictures and reference pictures. The effect of reduction of circuit size and power consumption of a HEVC encoder LSI with the proposed method is evaluated with power simulation, and the image quality is also evaluated with software simulation.
