A new implementation of image-processing engine for 3D visualization and stereo video stream display

This paper presents a new implementation of a high-definition image-processing engine, which mainly targets the 3-dimensional (3D) visualization and stereo video stream display of binocular display equipment. The engine is compatible with the mainstream analog and digital stereo videos in component format and is able to receive stereo composite video broadcast signals using an integrated analog stereo video decoder. The four modules include a spatiotemporal scaling transform engine, a 2D-3D converter, an image animating engine, and a 2D scalar operating in pipeline architecture to implement the video format conversion and the stereo effect enhancement. Furthermore, the data access, hardware structure, and system-level configurations are optimized. Finally, the proposed architecture is realized by 0.18 μm CMOS technology. The application-specific integrated circuit verification results show that the engine can generate a strong feeling of 3D immersion and high-definition image quality with minimal flicker. The chip has wide compatibility and an uppermost 1080P-processing capacity, which has approximately 3.5 million gates with about 43 mm² die size.
