Abstract

A car video device enabling wireless transmission to and from portable communication device includes an image processing unit, a packet signal input terminal, a driving recorder unit, a control unit, a wireless signal transmission unit, and a power input terminal. The control unit can receive signals from the image processing unit, the packet signal input terminal and the driving recorder unit, and transmits the received signals to the wireless signal transmission unit, which then wirelessly transmits the signals to a portable communication device, such as a smart mobile phone, a tablet computer or a portable computer. Therefore, the portable communication device may be directly used in the car for displaying image signals and serve as a menu operation host of various in-car safe driving devices, and it is not necessary to additionally mount an LCD display in the car.

Claims

1. A car video device enabling wireless transmission to and from portable communication device, comprising:

an image processing unit being capable of receiving image information from cameras inside and outside a car, and converting the received image information into digital signals for outputting;

a packet signal input terminal being connected to a communicator of a vehicle area network for receiving packet signals transmitted over the vehicle area network;

a driving recorder unit for recording all images, dates and time, as well as driving speeds in the process of driving the car;

a control unit being capable of receiving and storing image signals output to it from the image processing unit, and outputting image signals captured by a related one of the cameras according to a reverse signal or a turning light signal in the received packet signals; and

the control unit also receiving signals from the driving recorder unit and accordingly outputting the images stored in the driving recorder unit;

a wireless signal transmission unit being capable of receiving signals output by the control unit and wirelessly transmitting the received signals to a Wi-Fi certified portable communication device; and

the wireless signal transmission unit also being able to receive wireless signals transmitted from the portable communication device to do menu operation for accessing signals stored in and output by the control unit; and

a power input terminal being connected to an in-car power source for inputting power supply that is needed by all the above units to operate normally.

2. The car video device enabling wireless transmission to and from portable communication device as claimed in claim 1, wherein, in the case a reverse signal is acquired from the packet signals, the control unit first outputs image signals captured by a camera arranged at a rear side of the car when the car is in the reverse gear.

3. The car video device enabling wireless transmission to and from portable communication device as claimed in claim 1, wherein, in the case a turning light signal is acquired from the packet signals, the control unit first outputs image signals captured by a camera arranged at a left or a right side of the car.

4. The car video device enabling wireless transmission to and from portable communication device as claimed in claim 1, further comprising a digital TV receiver unit;

signals received by the digital TV receiver unit being transmitted to the control unit, which further transmitting the received signals to the wireless signal transmission unit for wirelessly transmitting to the portable communication device.

5. The car video device enabling wireless transmission to and from portable communication device as claimed in claim 1, further comprising a Bluetooth transmission unit, which is connected to an in-car stereo;

the Bluetooth transmission unit being able to receive sound signals from the portable communication device and output the received sound signals via the in-car stereo.

6. The car video device enabling wireless transmission to and from portable communication device as claimed in claim 1, wherein the portable communication device is selected from the group consisting of a smart mobile phone, a tablet computer, and a portable computer.

7. A car video device enabling wireless transmission to and from portable communication device, comprising:

an image processing unit being capable of receiving image information from cameras inside and outside a car, and converting the received image information into digital signals for outputting;

a reverse signal input terminal for transmitting a reverse signal;

a turning light signal input terminal for transmitting a turning light signal;

a driving recorder unit for recording all images, dates and time, as well as driving speeds in the process of driving a car;

a control unit being capable of receiving and storing image signals output to it from the image processing unit, and outputting image signals captured by a related one of the cameras on receipt of a reverse signal from the reverse signal input terminal or a turning light signal from the turning light signal input terminal; and

the control unit also receiving signals from the driving recorder unit and accordingly outputting the images stored in the driving recorder unit;

a wireless signal transmission unit being capable of receiving signals output by the control unit and wirelessly transmitting the received signals to a Wi-Fi certified portable communication device; and

the wireless signal transmission unit also being able to receive wireless signals transmitted from the portable communication device to do menu operation for accessing signals stored in and output by the control unit; and

a power input terminal being connected to an in-car power source for inputting power supply that is needed by all the above units to operate normally.

8. The car video device enabling wireless transmission to and from portable communication device as claimed in claim 7, wherein, in the case a reverse signal is received, the control unit first outputs image signals captured by a camera arranged at a rear side of the car when the car is in the reverse gear.

9. The car video device enabling wireless transmission to and from portable communication device as claimed in claim 7, wherein, in the case a turning light signal is received, the control unit first outputs image signals captured by a camera arranged at a left or a right side of the car.

10. The car video device enabling wireless transmission to and from portable communication device as claimed in claim 7, further comprising a digital TV receiver unit;

signals received by the digital TV receiver unit being transmitted to the control unit, which further transmitting the received signals to the wireless signal transmission unit for wirelessly transmitting to the portable communication device.

11. The car video device enabling wireless transmission to and from portable communication device as claimed in claim 7, further comprising a Bluetooth transmission unit, which is connected to an in-car stereo;
