Description

IMAGE TRANSMISSION DEVICE AND SYSTEM
BACKGROUND OF THE INVENTION
This invention relates generally to an image transmission device and system. In particular, the present invention relates to a device that integrates video recording equipment and a cellular telephone for transmitting live or recorded video and pictures to a remote location for viewing.
Video recorders and digital cameras are very popular for recording important events so that they may be viewed again and again at later times. For example, video recorders may be used to record a child's athletic events for later viewing by friends and family. The disadvantage of recording the event for later viewing, of course, is that those individuals must in fact wait until a later date — potentially much later — to see it. In other words, there is no convenient means for viewing the event immediately without actually attending the event. Various proposals have been made in the prior art for transmitting video or other digital data using cellular telephone technology. Although assumably effective for their intended purposes, the existing proposals do not provide a user- friendly device and system for integrating a video camera with a mobile communications device for on-the-spot transmission of a live event and transmitting it to a remote location for immediate viewing on a display.
Therefore, it would be desirable to have an image transmission device and system that is mobile and that directly integrates a video camera and a cellular telephone for transmission of digital images to a remote location for viewing. Further, it would be desirable to have an image transmission device and system that may be mounted to a traditional camera tripod and that may securely hold and connect to a user-supplied cell phone and camera. SUMMARY OF THE INVENTION
An image transmission device and system according to the present invention includes an image transmission device and a converter device that may be located remote from the image transmission device. The image transmission device includes a cradle adapted to secure a user-supplied communications device and to attach to a user-supplied video camera. The cradle includes circuitry for electrically connecting a data output port of the digital camera to a data input port of the communications device. The entire cradle may also be mounted to a camera tripod and may include an internal power source or be connected to an external power source for selectively recharging the batteries of the camera and communications device.
The converter is a unit for use with another communications device for receiving images being recorded by the camera at a live event and transmitted by the first communications device. The converter may be connected to a display for displaying the images in real time or for recording the images for later viewing.
Therefore, a general object of this invention is to provide an image transmission device and system for integrating a user-supplied camera with a user- supplied communications device.
Another object of this invention is to provide an image transmission device and system, as aforesaid, having a cradle for securing the communications device and camera and which provides circuitry for electrically connecting said devices.
Still another object of this invention is to provide an image transmission device and system, as aforesaid, which compresses data received from the camera prior to transmitting the data using the communications device. Yet another object of this invention is to provide an image transmission device and system, as aforesaid, in which the cradle may be mounted to a traditional camera tripod for user-friendly usage.
Another object of this invention is to provide an image transmission device and system, as aforesaid, in which the cradle includes a battery for selectively recharging the communications device or camera in use. A further object of this invention is to provide an image transmission device and system, as aforesaid, having a converter for use with another communications device at a location remote from the cradle.
A still further object of this invention is to provide an image transmission device and system, as aforesaid, in which the converter may decompress images received by the communications device and deliver them to a display device for immediate or recorded viewing by a person not at a live event.
Other objects and advantages of the present invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, an embodiment of this invention.

With specific reference to Fig. 5, the image transmission device 110 includes a cradle 112 having a first area 112a for receiving the first communications device 2 and means 114 for securing the first communications device 2 to the cradle first area 112a. As shown in Figs. 2 and 3, the securing means 114 preferably includes a plurality of oppositely disposed walls 115 being inwardly-biased for securing respective communications devices 2 of various sizes. An attachment mechanism 116 is preferably connected to the cradle 112 for releasably attaching the cradle 112 to the camera 4. More particularly, the camera 4 preferably defines a threaded opening 4b, and the attachment mechanism 116 is preferably a threaded bolt 117 having a configuration complementary to a configuration of the camera threaded opening 4b.
A second attachment mechanism 118 is preferably connected to the cradle 112 for releasably attaching the cradle 112 to a tripod (the tripod is not shown). In a preferred embodiment, the cradle 112 defines an opening 119 having a configuration complementary to a configuration of a tripod attachment bolt (not shown) for releasably attaching the cradle 112 to the user-supplied tripod. Other attachment mechanisms 118, such as clips and connectors, for example, may also be used.
With particular reference to Figs. 1 and 5, the image transmission device 110 includes circuitry 120 to selectively connect a data output port 4a of the camera 4 to a data input port 2a of the first communications device 2 for transferring data from the camera 4 to the communications device 2. The circuitry 120 preferably includes first and second electrical cords 122, 124. The first electrical cord 122 extends from the cradle 112 and has a connector 122a compatible with the camera output port 4a; the second electrical cord 124 extends from the cradle 112 and has a connector 124a compatible with the communications device data input port 2a.
As detailed in Fig. 8, means 126 for compressing the data transferred from the camera 4 to the first communications device 2 may be housed in the cradle 112. The means 126 preferably include a processor 126a housed inside the cradle 112 and electrically connected to the circuitry 120. The processor 126a includes software for compressing the data transferred from the camera data output port 4a and transferring the compressed data to the communications device data input port 2a.
Additional circuitry 130 may be included in the image transmission device 110 (Fig. 9). The additional circuitry 130 is preferably in selective communication with a power source 136, a power input port 4c of the camera 4, and a power input port 2b of the first communications device 2 for selectively powering the first communications device 2 and the camera 4, respectively. The power source 136 may be a battery positioned in the cradle 112, or the power source 136 may be conventional AC current.
As best understood with reference to Figs. 4A, 4B, 7, and 10, the converter 140 is remote from the image transmission device 110 and has circuitry 150 to selectively connect a data output port 6a of the second communications device 6 to a data input port (not shown) of the display 8 for transferring the data from the second communications device 6 to the display 8. The converter 140 may include means 156 for decompressing the data and a storage unit 158 for storing the data. The circuitry 150 is preferably in electrical communication with a power source 7 for energizing the circuitry 150, as shown in Fig. 7.
In use, the first communications device 2 may be secured to the cradle first area 112a of the image transmission device 110 by utilizing the securing means 114. The cradle 112 may be attached to the camera 4 by the attachment mechanism 116, and the cradle 112 may be attached to the tripod by mating the tripod attachment bolt with the cradle opening 119.

More particularly, the first electrical cord connector 122a is attached to the camera output port 4a, and the second electrical cord connector 124a is attached to the first communications device data input port 2a. The converter circuitry 150 connects the data output port 6a of the second communications device 6 to the data input port of the display 8. Data is transferred from the camera 4 to the first transmission device 2 using the image transmission device circuitry 120. The data may be compressed by the compressing means 126 before reaching the first transmission device 2. After reaching the first transmission device 2, the data is transferred from the first communications device 2 to the second communications device 6 using known data-transmission methods, such as cellular technology. Upon reaching the second communications device.6, the data is transferred to the display 8 by the converter device circuitry 150. Before the data reaches the display 8, the decompressing means 156 may decompress the data. Further, the converter storage unit 158 may store the data for later viewing. The additional circuitry 130 of the image transmission device 110 may be connected to the power source 136, the camera power input port 4c, and the first communications device power input port 2b. The user may then selectively power the camera 4 and the first communications device 2 from the power source 136. It is understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
