Car sellers used to lay emphasis on the horsepower and performance of a car when selling the car. However, with the development of techniques, the cars purchased by general consumers are almost the same in performance. Therefore, more and more car sellers begin to emphasize equipping the car with a variety of high-tech products. Some emphasize providing the car with multiple charge couple devices (CCDs) to assist in driving video. Some emphasize providing the car with multiple antennae respectively for wireless sending/receiving of a Digital Video Broadcasting (DVB), a Global Positioning System (GPS) or a Global System for Mobile Communication (GSM). However, too many technical equipments used in the car always result in too many lines that seem disorderly and unsystematic, which causes an increase in the overall cost and power consumption of the car due to respective and separate operations of various technical equipments in additional to the difficulty in arranging the lines.
The present invention is directed to an image acquisition device with an antenna module, which is capable of avoiding the difficulty in arranging the lines and meanwhile the increase in the overall cost and power consumption.
The image acquisition device with an antenna module disclosed in the present invention includes an image acquisition unit, an antenna module, and a signal transmission line. The image acquisition unit is used for acquiring an image. The antenna module has at least one antenna unit for sending/receiving at least one signal. The signal transmission line includes a first signal line and a second signal line. The first signal line is electrically connected to the image acquisition unit, such that the image acquisition unit delivers the image via the first signal line. The second signal line is electrically connected to the antenna module, such that the antenna module delivers the signal via the second signal line.
The image acquisition device with an antenna module disclosed in the present invention further includes a system host and a display interface. The system host is electrically connected to the signal transmission line, and has a processor for analyzing the image and the signal delivered by the signal transmission line after being received by the system host. The display interface is electrically connected to the system host, such that the processor presents the analyzed image and the signal on the display interface. The system host further includes a data storage unit. The data storage unit is electrically connected to the processor, for storing the image and the signal.
The image acquisition device with an antenna module of the present invention integrates the image acquisition unit and the antenna module to achieve the effect of reducing the cost, and at the same time may further use the functions of the image acquisition unit and the antenna module simultaneously to achieve the functions such as driving recording in addition to the antenna function and image acquisition function it originally has. On the other hand, the image acquisition device with an antenna module of the present invention may reduce the problem of arranging the lines through integrating the first signal line and the second signal line into the signal transmission line.
The present invention will become more fully understood from the detailed description given herein below for illustration only, and thus are not limitative of the present invention, and wherein:
The features and practices of the present invention are hereby illustrated in detail below in combination with the drawings.

The image acquisition unit 22 is used for acquiring an image. The image acquisition unit 22 may be a charge couple device (CCD), but it certainly may also be a complementary metal oxide semiconductor (CMOS).
The antenna module 23 has at least one antenna unit for sending/receiving at least one signal. The antenna module 23 includes at least one of a Digital Video Broadcasting ( DVB )antenna, a Global Positioning System ( GPS )antenna, a Global System for Mobile Communications ( GSM ) antenna, and a radio frequency (RF) antenna.
The signal transmission line 24 includes a first signal line 27 and a second signal line 28. The first signal line 27 is electrically connected to the image acquisition unit 22, such that the image acquisition unit 22 delivers the image via the first signal line 27. The first signal line 27 is, but not limited to, a twisted line.
The first embodiment of the present invention further includes a system host 21 having a processor 25, and the processor 25 has multiplexing capabilities such as operating and analyzing. The system host 21 may further include a data storage unit 26 electrically connected to the processor 25, for storing the image and the signal. The data storage unit 26 may be a hard disk, a universal serial bus (USB) disk, or another data storage device such as a memory card.
The first signal line 27 is electrically connected with the system host 21 through a universal serial bus (USB) interface, but it certainly may also be electrically connected with the system host 21 through other connection interfaces. The second signal line 28 has one end electrically connected to the antenna module 23 and the other end electrically connected to the system host 21, such that the antenna module 23 delivers the signal via the second signal line 28 to the processor 25 to be analyzed. The second signal line 28 is, but not limited to, a coaxial signal line. The second signal line 28 is electrically connected with the system host 21 through an RF connection interface, but it certainly may also be electrically connected with the system host 21 through other connection interfaces.

The image acquisition device with an antenna module according to the first embodiment of the present invention further includes a housing 29. The image acquisition unit 22 and the antenna module 23 are disposed in the housing 29. A first hole 30 is opened in the housing 29, such that the image acquisition unit 22 acquires an image outside through the first hole 30. The first hole 30 is further provided with a transparent material, such as glass and plastics, for protecting the image acquisition unit 22. At least one second hole 31 is further opened in the housing 29, such that the signal transmission line 24 passes through the second hole 31, and has its one end electrically connected to the image acquisition unit 22 and the antenna module 23 respectively and the other end electrically connected to the system host 21.
In the image acquisition device with an antenna module according to the first embodiment of the present invention, through integrating the first signal line 27 and the second signal line 28 by the signal transmission line 24, the lines required to be used are simplified to reduce the problem of arranging the lines. On the other hand, the originally separately operated image acquisition unit 22 and the antenna module 23 are integrated, such that the functions such as driving recording may be achieved by operating the functions of the image acquisition unit 22 and the antenna module 23 simultaneously, in addition to the original antenna function and image acquisition function.

In the image acquisition device with an antenna module according to the second embodiment of the present invention, the signal received by the antenna module 23 is presented on the display interface 32 after being analyzed by the processor 25. For example, the DVB signals or the global satellite positioning signals etc. are received to allow the user to watch the DVB or the current driving navigation route in real time. On the other hand, the acquired image is presented on the display interface 32 after the processor 25 analyzes the signal received by the image acquisition unit 22. For example, when parking or backing a car, the distances between the cars are displayed on the display interface, and the function of a driving image recorder is also achieved by combining the signal of the antenna module 23 and the image of the image acquisition unit 22 simultaneously.
