Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television set using a mobile telephone line for capturing images taken by a camera installed in a remote place.
The present invention relates to an image transmission device that transmits an image to an image acquisition terminal such as a monitor or a personal computer.

[0002]

2. Description of the Related Art FIG. 5 shows an example of this type of image transmission apparatus according to the prior art. As shown in FIG. 5, the image transmission apparatus 100 includes a camera 101 and a case 102 that houses the camera 101. The image captured by the camera 101 is transmitted by wire to an image acquisition terminal (not shown).

[0003] The case 102 is supported by a swivel 103 capable of turning up and down and turning horizontally.

[0004] A conventional image transmission apparatus 10 having such a configuration is described.
0 is currently installed for the purpose of monitoring traffic on roads or observing the ecology of wildlife in forest areas.

[0005]

In the above-described image transmission apparatus, the image taken by the camera 101 is conventionally transmitted to the image acquisition terminal in a wired manner, so that it is difficult to install the image transmission apparatus in a mountain without a wired cable facility. There was a huge expense required to set up a wired cable facility.

A case 1 in which the camera 101 is built
Reference numeral 02 is usually mounted on a swivel table 103 capable of performing an elevating swing operation and a horizontal swiveling operation so that a wide area can be photographed.

[0007] However, since the heavy case 102 itself is operated, a large capacity of a motor for performing the elevation rotation drive and the horizontal rotation drive built in the swivel table 103 is required. The size itself also increases. For this reason, there is also a disadvantage that the outer shape of the swivel base is increased and the weight is inevitably increased.

[0008] Such an image transmission device is often installed outdoors as described above, and the camera 1 is used in winter.
In general, the case 102 has a built-in heater for keeping heat, but the turntable 103 generally does not have a built-in heater for keeping the motor warm. For this reason, the lowest usable ambient temperature is about -10 ° C, and it cannot be used in severe cold regions where the temperature reaches -30 ° C.

Therefore, a technical problem of the present invention is that it can be installed and used in a mountain or the like where there is no wired cable facility, or in a severely cold area where the temperature reaches -30 ° C in winter.
Another object of the present invention is to provide an image transmission device having a small and lightweight swivel.

[0010]

According to the present invention, there is provided an image transmission apparatus for transmitting an image photographed at a remote place to an image acquisition terminal, comprising: a camera comprising one of a digital camera and a CCD camera; An image transmission device, comprising: a camera elevating / turning unit that drives a camera to elevate / turn; a case that houses the camera and the camera elevating / turning unit; and a swivel table that guides and supports rotation of the case. can get.

Further, according to the present invention, in the image transmission device, further, an image transmission modem and a mobile phone for transmitting an image photographed by the camera, and horizontal turning means for turning the camera in a horizontal direction. Wherein the case further houses the image transmission modem, the mobile phone, and the horizontal turning means.

Further, according to the present invention, there is provided the image transmitting apparatus, wherein the camera elevating / turning means drives only the camera in an elevating / turning manner.

Further, according to the present invention, in the image transmission device, the image photographed by the camera is transmitted to an image acquisition terminal via a portable telephone line via the portable telephone and the image transmission modem. As a result, a characteristic image transmission device is obtained.

Further, according to the present invention, in any one of the image transmission apparatuses, when installed in a severely cold region, the storage case is provided with a heat retaining means for preventing a temperature drop in the case. An image transmission device characterized by the above is obtained.
