[0039] will refer to Figures 1 to 3C A first embodiment of the present invention will be described.
[0040] Such as figure 1 As shown in , the information presentation apparatus according to this embodiment is configured as a personal digital assistant (PDA) 10 equipped with a camera 11 . Also, assume that the predetermined mark 20 is, for example, an alphanumeric character or mark surrounded by a rectangular frame.
[0041] The camera-equipped PDA 10 performs the following operations in accordance with the internal procedure performed while capturing the above-mentioned predetermined marks 20 and pipes 30 . That is, spatial positioning information such as deformation and size of the above-mentioned predetermined marker 20 in the captured image is analyzed by image processing. Then, the pipe name 40 registered in advance in the camera-equipped PDA 10 as related information is displayed so as to be superimposed on the corresponding pipe image 30' on the screen 12 of the ca...

[0051] Next, we will use the Figure 4A and 4B A second embodiment of the present invention will be described. In this embodiment, the prompt information not only involves the spatial positioning information of the target object and / or the predetermined marker 20 in the real world, but also involves the spatial positioning information of any target object. Specifically, as the prompt information, there is provided information prompting an easily distinguishable target object as a mark, and prompting a target at a position farther from the predetermined mark 20 than the visual angle 13 or more of the image input device provided for the information presentation device object information. exist Figure 4A and 4B In the example of , the picture 60 is set as an example of a target object that is easily recognized as a mark, and the fire extinguisher 70 is set as a target object at a viewing angle or more away from the predetermined mark 20 from the image input device. Note tha...

[0056] Next, we will use the Figure 5 A third embodiment of the present invention will be described. In this embodiment, it is assumed that the prompt information is the position ( Figure 5 The cube in 41) has the information at the position of the given relative relationship ( Figure 5 Thick-line rectangular frame in : a frame image 50D that surrounds the marker image 20 ′ and serves as hint information for the marker position.
[0057] In this way, the hint information has a given relative relationship to the related information ( Figure 5 shown in dotted line 80). Therefore, by observing the difference between the prompt information on the screen 12 and the position of the actual target object or marker 20, not only the accuracy of the value of the relevant information, but also the accuracy of the direction of the relevant information can be evaluated.
[0058] For example, if Figure 5 As shown in , when the actual marker image 20' is at the lower left of the pro...
