Abstract— Recently, a variety of external accessory devices have been developed for smart phone. Among them, external devices which communicate via earphone jack on smartphone are prominent because they are small and compact and can be fixed on smartphone. This method is ideal for devices that do not require high-speed data transfer. In this paper, we present data transmission via smartphone earphone jack for infrared depth maps. Depth map is an image or image channel that contains information relating to the distance of the surfaces of scene objects from a viewpoint. And it can be measured using IR camera. We are now developing a compact image sensor that produces depth map of image.
Index Terms— IR, depth map, earphone jack, triangulation.
