Description

  The present invention relates to a communication device, a communication program, and an image display system.

  When image data is transmitted and received by two different types of terminals and the received image data is displayed in the display area of the terminal, there is a possibility that unintended reduction of the image data may occur. In particular, the display area of the smartphone is vertically long, and the display area of a display device such as a monitor or a projector is horizontally long. Therefore, when an image captured by a smartphone is to be displayed on a projector, there is a problem that the image is reduced and displayed in a format not intended by the user. In order to solve the problem, there is known a technique in which a user selects a finder that fits the display device at the time of shooting and shoots an image (see, for example, Patent Document 1).

  In the above-described prior art, photographing can be performed in accordance with the aspect ratio and shape of the display device that displays an image. However, it is necessary for the user to select the shape of the finder which matches the aspect ratio and shape of the display device, and there is a problem that complicated processing occurs for the user. In addition, it is necessary for the user to know the aspect ratio, the shape, and the like of the display device, and for a user who does not have knowledge of the aspect ratio and the shape, the selection of the shape of the finder has a further problem.

  The present invention has been proposed in view of the above-described conventional problems, and the object of the present invention is a communication device capable of photographing in a format compatible with a display device without requiring the user to perform complicated processing. A communication program and an image display system are provided.

In order to achieve the above object, for example, a communication device is a receiving unit that receives display function information related to the display function of the display device from the display device, a photographing unit, and recording image data photographed by the imaging unit. Display means for causing the display unit to display the recording means, the image data, and the frame indicated by the display function information, and the display device displaying image data of a portion of the image data contained in the frame The display means moves the frame based on a user's instruction, and the display function information is included in the acquired SSID .

FIG. 7B is an example in which a frame G7 having an aspect ratio of 16:10 is displayed in the finder G6. By having such a configuration, the user can know how the image data is displayed on the projector 2 during shooting.

  In addition, when an operation of rotating the vertical and horizontal directions of the communication terminal 3 is performed, the finder generation unit 34 regenerates the finder according to the aspect ratio included in the display function information. FIG. 8 is a view showing an example of a finder displayed when the communication terminal is rotated from the vertical direction to the horizontal direction.
