Description

  The present invention relates to a mobile phone having a remote control photographing function capable of performing a photographing operation at a position away from a photographing position.

  Most recent mobile phones are equipped with a camera. In addition to a call function, a function for displaying a captured image or preview image, a function for capturing an image and storing the captured image, and transmitting the captured image And a function of receiving and displaying image information from another mobile phone.

By the way, as a useful function in the camera, there is a function capable of performing a photographing operation from a remote position, that is, a remote control photographing function. The conventional remote control photographing function is, for example, remote control using optical communication as in Patent Document 1. It is.
JP-A-7-107567

  The conventional remote control photographing function was incorporated as a part of a camera or a camera accessory device as exemplified in Patent Document 1. With such a remote control shooting function, a remote control operation position and a camera are installed, the distance between the positions where shooting is performed is limited, and remote control shooting exceeding several tens of meters is impossible.

  However, in the remote control shooting function, if there is no restriction on the distance between the remote control operation position and the shooting position, the utility value of the remote control shooting function is remarkably high. For example, in order to monitor and photograph a changing site situation from a remote location, a large-scale and expensive monitoring device has been conventionally required. However, if monitoring and photographing can be performed using a remote control photographing function of a commonly used camera. Easy and inexpensive monitoring is possible, and it is possible to execute immediately when monitoring and shooting are required without requiring special preparation such as installation of a monitoring device. It will be useful.

  An object of the present invention is to provide a mobile phone having a remote control shooting function having a high utility value without any limitation on the distance between the remote control operation position and the shooting position by using the communication function of the mobile phone. To do.
