Embodiment Construction

[0026] Next, preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited to this embodiment. In addition, in description of each figure, the same part is attached|subjected and shown by the same code|symbol.

[0027] figure 1 It is a schematic perspective view showing the front side of a digital camera 1 of a portable device to which the present invention is applied, figure 2 It is a schematic perspective view showing the rear side of the digital camera 1 . Such as figure 1 As shown, a digital camera 1 is provided with an imaging lens 4 on the front of a camera body 3, and has an imaging unit 11 inside the camera body 3 for capturing an image of a subject incident through the imaging lens 4 (refer to Figure 9 ). On the other hand, on the upper surface of the camera body 3, a release switch 5 for indicating a shooting timing is arranged. Also, on the back of the camera body 3 are a...

Abstract

A communication control unit performs communications with an external device via a first wireless communication unit of which communication distance is short and which is capable of performing high-speed communications or a second wireless communication unit of which communication distance is long compared with the first wireless communication unit and which is capable of performing low-speed communications. A communication state judging unit judges a communication state of the communications with the external device via the first wireless communication unit or the second wireless communication unit. The communication control unit performs switching between the communications with the external device via the first wireless communication unit and the communications with the external devicevia the second wireless communication unit based on the communication state judged by the communication state judging unit and / or a transmission data amount to be transmitted to the external device.

Description

technical field [0001] The present invention relates to portable devices. Background technique [0002] Conventionally, it has been common practice to connect a digital camera to an external device such as a personal computer, and to transmit images captured by the digital camera to the external device. Also, Japanese Patent Application Laid-Open No. 2005-286654 discloses a technique in which a digital camera is provided with a plurality of communication interfaces for the purpose of increasing communication speed, and these communication interfaces are operated simultaneously to transmit data. [0003] However, in the case of transmitting the image captured by the digital camera to the external device as described above, work such as connecting a cable to the external device is required every time, which is very troublesome. On the other hand, if data is transmitted and received by wireless communication between the digital camera and the external device, such work is not ...
