This paper describes an algorithm for creating pseudo stereo image generation (2D-to-3D conversion) and its real-time hardware implementation. The proposed method is developed to fulfill the growing need for high quality generic 3D contents. The algorithm intends to approximate 3D structures of natural scenes and to generate visually pleasing stereo images. The depth data is generated with simple models and by warm/cool color theories. The algorithm has advantages in picture quality, low numerical complexity, and no need of tuning of parameters for different types of pictures. The hardware implemented with the simple algorithm does not need any large memory such as frame memory and gives very low latency. This technology had attracted many people's attentions at demonstrations including CEATEC 2008.
