Since it is imported from the Web server 21 (or exceptionally from a miniSD card) and recorded on the hard disk 34, the character portion (text data) can also be automatically output to the ledger (thus, as in the prior art). In addition, the user does not have to manually enter the same characters that are handwritten on the actual blackboard in the construction photo).

  As described above, according to the first embodiment, even one person uses the mobile phone 1 to input the electronic blackboard character data on the construction site and generate an electronic blackboard image. It is possible to capture and acquire a construction photograph in which a blackboard image is imprinted together and upload it to the Web server 21 (and / or record it on a miniSD card). On the office side, the construction photo with the electronic blackboard and the character data of the electronic blackboard are received from the Web server 21, and the construction management ledger including the construction photo with the electronic blackboard is received based on the received data. A construction report including this can be automatically created.

  In the first embodiment, before the operator takes a construction photograph with an electronic blackboard at the site, the position and size of the electronic blackboard within the photographing range can be arbitrarily set on the blackboard data input screen (see FIG. 3). Since it is possible to select and specify, the operator can arbitrarily adjust the position and size of the electronic blackboard according to the actual construction situation to be imaged and the position and size of the background part (distant mountain and sky, etc.) Therefore, it is possible to capture and acquire a construction photograph in which an electronic blackboard of an optimal size is imprinted at an optimal position.

  In the first embodiment, the current position coordinate data at the time of shooting from the GPS receiver 18 is recorded in association with the acquired construction photo with electronic blackboard (for example, the construction photo image file with electronic blackboard). The information is additionally recorded in a predetermined item of the property), and is further transmitted to the Web server 21, so that the user of the construction company can, for example, capture the attribute information of the construction photo with the electronic blackboard at the time of shooting. Position coordinate data can be included, and the reliability of construction photographs with an electronic blackboard can be increased. In addition, when creating a construction report, the user can automatically display and print map information corresponding to the position coordinate data at the time of shooting along with the construction photo with the electronic blackboard in the ledger, etc. The usage scene of can be expanded.

  Next, the acquisition of construction photographs with an electronic blackboard using a mobile phone according to the second embodiment and the construction report automatic creation system using the photographs will be described with reference to FIG. Since the basic configuration of the second embodiment is the same as that of the first embodiment, only different parts will be described below, and the other description will be omitted.

  In the second embodiment, a part of the configuration (mobile application) of the mobile phone 1 in FIG. 20 is different from that in the first embodiment. That is, in the second embodiment, as the configuration (mobile application) of the mobile phone 1, instead of the blackboard position selection unit 16 and the blackboard size selection unit 17 of the first embodiment, the blackboard position automatic determination unit 51 and the blackboard size automatic A determination unit 52 is provided.
