<P>PROBLEM TO BE SOLVED: To provide an information output device, information output method, and program in which throughput of data to be handled can be reduced even when a captured image region is large, and a data transfer amount can be increased as a result. <P>SOLUTION: A light receiving unit 40 initializes a read region range of an imaging section 45 or a timing generator, then fetches a frame image from the imaging section 45 into a capture image frame buffer 46, stores the fetched image in a plane designated by a buffer pointer n, and updates the buffer pointer. When the buffer pointer becomes a maximal value, signal detection & bit extraction processing is performed and when bit data are buffered for 1 byte, an image in a display buffer 47 is transferred to a liquid crystal display 44 and displayed thereon. In such a case, if there is no detection signal in the signal detection processing, processing is switched to next read region range processing (step S32) and for the read region range, similar processing is repeated. <P>COPYRIGHT: (C)2008,JPO&INPIT |
