Description

The present invention relates to a communication apparatus and a control method therefor , and more particularly to a communication apparatus that establishes a connection with a device in a network and a control method therefor .

This onset Ming, using a discovery protocol for discovering devices in a network, and an object thereof is to provide a communication device and a control method thereof to connect with a device in the network can be easily performed.

An object of the present invention is to provide a communication apparatus having an imaging unit that establishes a connection with a device using a discovery protocol for discovering a device in the network, and transmits a search command for searching for a device in the network. One transmission means, a first reception means for receiving device information transmitted from a device in the network in response to the search command, and one of the devices based on the device information received by the first reception means. First selection means for selecting, and second transmission means for transmitting a notification signal for notifying the presence of a communication apparatus to a device in the network after selection by the first selection means. This is achieved by a communication apparatus having imaging means.

According to the present invention, it is possible to provide a communication apparatus that can easily connect to a device in a network and a control method thereof using a discovery protocol for discovering a device in the network .

[Digital camera configuration]
In the following description, a digital camera capable of shooting still images and moving images will be described as an example of a communication apparatus according to the present invention. Note that a device including a digital camera, such as a so-called camera-equipped mobile phone or a camera-equipped tablet device, is also an example of a communication device.

In the present embodiment , the digital camera 100, which is a device with a built-in wireless communication function, has been described as an example of a communication device . However, the present invention is also applicable to a device that provides a wireless communication function that can be attached to other devices. Can be applied. For example, the recording medium 141 is as long as the radio communications available-recording medium, may be configured to the recording medium 141 controls the wireless communication. In this case, the same control as the embodiment performs the wireless circuit unit (not shown) of the recording medium 141 capable of wireless communication.
