White-RGB (WRGB) color filter array (CFA)-based CMOS sensor is a new and popular technique to improve the image quality directly with a higher sensitivity White (W) filter. Considering there is no color information in the pixel assigned to W, color separation from W raw data is necessary. We propose a color separation method based on a novel physicallike virtual color filters model for the WRGB CFA-based...
In this paper, we propose a novel high speed VLSI architecture of full search-variable block size motion estimator (VBSME) supporting multiple reference frames. In the proposed architecture, four current macrobocks are concurrently compared with a single search window (SW) of the reference frame to find the best matched block.By reusing the SW of the reference frame and scheduling the architecture...
