Abstract

The invention provides an information retrieval apparatus and an information retrieval method by which information can be retrieved in an improved operability. A CPU controls a video camera to fetch an image and controls a GPS to detect a current position. The CPU reads out, from within image data stored in a corresponding relationship with URLs of WWW servers, those image data which correspond to position data regarding positions around the detected current position from a WWW data base via a modem and a host machine. Then, the CPU selects, from among the read out image data, that image data which matches with the fetched data, reads out a URL corresponding to the image data and accesses a WWW server designated by the URL.
