When schedule information 22 composed of identification information 21 composed of time information and availability information as a title and corresponding message information 24 is input, the input schedule information is stored in the display information memory 14.
At the time of the imaging operation, when the title creation mode is set from the operation board 12, based on the date / time data taken in from the clock circuit 16, the operation circuit 12 has information indicating that the title can be used. Message information 24 of date / time information closest to date / time data from
Is retrieved from the display information memory 14 as a title,
The searched title is added to the image of the subject displayed on the display 20. When the schedule display mode is set on the operation board 12, the schedule information written from the keyboard 11 is displayed on the display 20 as it is as a schedule table.

For this reason, according to the present embodiment, the retrieval of the title of the captured image from the schedule information and the insertion and superposition as the title in the captured image are automatically performed, and the appropriate title is superimposed. The captured image can be automatically displayed, and the schedule information can be displayed on the display 20 as it is as a schedule table and used.

In the above embodiment, as the identification information,
Although the case where the date / time information and the availability information as the title are used has been described, the present invention is not limited to this embodiment, and for example, encodes a country name, a place name, an event name, and the like. It is also possible to use the message information corresponding to the target identification information as the title by using the identification information and using the designation signal corresponding to the code inputted from the keyboard when searching for the title.
