FIG. 15 is a processing flow for creating and sending an e-mail. 11 “Address” input, 12 “Subject” input, 13 “Text input”, 14 Image file attachment processing unit, 15 “Mail” It consists of “Send” input, determination of whether to attach 14 “image file” to mail, 15 “image file” selection, 16 “send mail” input, and 20 “mail” transmission processing.

  Generally, the procedure for creating and sending an e-mail is as follows: 11 “address” input, 12 “subject” input, 13 “text input”, and 14 “image file” attached to the e-mail If 15 “image file” is selected and “image file” is not attached, 15 “image file” is not selected, 16 “mail transmission” input is executed, and 20 “mail” is selected. The transmission process is executed.

  However, since the moving image data and still image data attached to the e-mail at this time are separate files from the e-mail, the moving image data and still image data are stored independently from the e-mail. It is possible to manage.

  As a result, the moving image data and still image data attached to the e-mail are temporarily stored in the PC, mobile phone, and information device as independent files separate from the e-mail. When saved, information such as how the moving image data and still image data are obtained files is lost. For this reason, it becomes difficult to specify the acquisition route of moving image data or still image data.

  Here, for the purpose of explanation, as a procedure for creating an e-mail, 11 “address” input, 12 “subject” input, 13 “text input”, and 14 “image file” are attached to the mail. The “image file” selection has been described in order, but the procedure for creating an actual e-mail is not limited to the input order of 11, 12, 13, and 14, 15; Items other than input can be arbitrarily input.

  In the technology according to the present invention, when an e-mail is created and transmitted, only when the “image file” is attached to the e-mail, the “image information” (“address”, “subject”, “text” is added to the “image file”. ”) Is added as QR Code image converted information, and then an e-mail is transmitted.

  FIG. 3 shows a third form of the first embodiment of the present invention. FIG. 3 shows an example of a screen on a mobile phone, which is 21 mail creation screens. “Mail”, “Subject”, “Body”, “Attachment”, and “Mail transmission” in the mail creation of 21 are 11 “address” input, 12 “subject” input in the processing flow of FIG. This corresponds to 13 "text input", 14 image file attachment processing units, and 15 "mail transmission" input.
