An arrangement is provided in which previously sensed image information is stored, so that information with an angle desired by the user can be searched for and displayed. Image data sensed by a camera device (100) is captured by an image information capture unit (101) and the angle information of image data captured by the image information capture unit (101) is acquired by an image view point information acquisition unit (102). A header is generated by a header generation unit (103) based on the angle information. A recording information generation unit (104) generates recording information based on the generated header and the captured image data, and stores the generated information in an external storage device (6). Upon reception of an external search instruction, a search unit (105) searches for information matching angle information included in the search condition, and an output unit (106) outputs the found image data.
