<P>PROBLEM TO BE SOLVED: To provide an information terminal device capable of controlling information displayed on a display part without loading additional hardware such as an acceleration sensor by changing spatial positional relation between a photographing part and a photographic target. <P>SOLUTION: The imaging part 11 inputs an optional image at a prescribed interval. An estimation part 12 analyzes the input image, and estimates the change of the spatial positional relation between the photographing part 11 and the photographic target. Display information displayed by the display part 15 is previously developed on a memory 14. A control part 13 reads the corresponding display information on the memory 14 in accordance with the change of the spatial positional relation between the photographing part 11 and the photographic target estimated by the estimation part 12, and sends it out to the display part 15. The display part 15 displays the display information sent out from the control part 13. It is also possible to estimate the change of the spatial positional relation between the photographing part 11 and the photographic target by reading a bar code. <P>COPYRIGHT: (C)2007,JPO&INPIT |
