The following refers to
The reversing image display system with packet selection mechanism includes a reversing image display device 10, a wireless receiver 20 and a remote controller 30, and the wireless receiver 20 include a receiving module 21, a packet filter module 22, a packet parsing module 23, an authentication module 24 and a transmitting module 25.
In a step 101, a reversing image display device 10 is provided and disposed at the rear of vehicle, and in a step 102, the reversing image display device 10 can be interconnected with the wireless receiver 20 by a wired transmission manner or a wireless transmission manner. Preferably, the wired transmission manner may be the manner of using a transmission cable, and the wireless transmission manner may be Wi-Fi, Bluetooth, ZigBee and so on; however, these examples are merely for exemplary illustration, and the application field of the present disclosure is not limited thereto.
The remote controller 30 can be interconnected with the wireless receiver 20 by the wireless transmission manner. Preferably, the wireless transmission manner can be Wi-Fi, Bluetooth, ZigBee and so on; however, these examples are merely for exemplary illustration, and the application field of the present disclosure is not limited thereto. In an embodiment, the remote controller 30 may include an up arrow key, a down arrow key, a right arrow key, a left arrow key, a confirmation key and a mode selection key; however, these examples are merely for exemplary illustration, and the application field of the present disclosure is not limited thereto.
In a step 103, the receiving module 21 of the wireless receiver 20 receives at least one wireless packet by the wireless transmission manner; and in a step 104, the remote controller 30 transmits the wireless packet by the wireless transmission manner. The wireless packet received by the receiving module 21 of the wireless receiver 20 may be transmitted from the remote controller 30 or other device, for this reason, the wireless packet are further filtered by the packet filter module 22 of the wireless receiver 20.
In a step 105, according to frame information of the wireless packet received by the receiving module 21 of the wireless receiver 20, the packet filter module 22 of the wireless receiver 20 is able to filter out the wireless packet corresponding to the reversing image display device 10.
The wireless packets 41 are filtered by the packet filter module 22 of the wireless receiver wireless receiver 20, and the frame information of the wireless packet 41 can include a MAC field, an ID field, a Magic Byte field, a command field, a checksum field, an addressing field, and so on. The packet filter module 22 of the wireless receiver 20 can filter the wireless packets 41 to select the wireless packet corresponding to the reversing image display device 10 according to the MAC field and the addressing field of the frame information of the wireless packet 41. For example, when the MAC field and the addressing field of the frame information of the wireless packet 41 matches with the reversing image display device 10, the packet filter module 22 of the wireless receiver 20 can determine that the wireless packet 41 corresponds to the reversing image display device 10, and filter out the wireless packet 41. When the MAC field and the addressing field of the frame information of the wireless packet 41 does not match with the reversing image display device 10, the packet filter module 22 of the wireless receiver 20 determines that the wireless packet 41 does not correspond to the reversing image display device 10.
In a step 106, after the packet filter module 22 of the wireless receiver 20 filters out and select the control signal 42 corresponding to the reversing image display device 10, the packet parsing module 23 of the wireless receiver 20 parses packet content of the selected wireless packet, so as to obtain an authentication identifier and a control signal 42. The authentication identifier can be used to confirm that the filtered wireless packet is transmitted from the remote controller 30, not from other device.
In a step 107, after the packet parsing module 23 of the wireless receiver 20 parses the authentication identifier and the control signal 42, the authentication module 24 of the wireless receiver 20 performs authentication on the authentication identifier, for example, the authentication module 24 of the wireless receiver 20 can compare the authentication identifier with an identifier pre-stored in the wireless receiver 20 to check whether the authentication identifier matches with the identifier. When the authentication identifier matches with the identifier pre-stored in the wireless receiver 20, the authentication identifier passes the authentication of the authentication module 24; otherwise, when the authentication identifier does not matches with the identifier pre-stored in the wireless receiver 20, it indicates that the authentication identifier fails to pass the authentication of the authentication module 24 of the wireless receiver 20; however, these examples are merely for exemplary illustration, and the application field of the present disclosure is not limited thereto.
In a step 108, after the authentication identifier passes the authentication of the authentication module 24 of the wireless receiver 20, the transmitting module 25 of the wireless receiver 20 transmits the control signal 42 to the reversing image display device 10 by the wired transmission manner or the wireless transmission manner.
In a step 109, after the reversing image display device 10 receives the control signal 42 from the transmitting module 25 of the wireless receiver 20, the reversing image display device 10 executes the function corresponding to the control signal 42; for example, the reversing image display device 10 may perform an image process to magnify a part of the reversing image in response to the control signal 42; or, the reversing image display device 10 performs an image process to switch an image viewing angle of the reversing image. Preferably, the image process for switching the image viewing angle may include image process technology of image fisheye correction, image cropping processing, image white balance processing, image exposure processing, or a combination thereof. However, these examples are merely for exemplary illustration, and the application field of the present disclosure is not limited thereto.
The control signal 42 may include mode information and a control instruction, and the control signal 42 is generated correspondingly to a user's action of pressing the up arrow key, the down arrow key, the right arrow key, the left arrow key, the confirmation key or the mode selection key of the remote controller 30. That is, the user can press the mode selection key to select a desired mode to trigger corresponding mode information (that is, different selected modes can trigger different mode information), and the user can then press the up arrow key, the down arrow key, the right arrow key, the left arrow key or the confirmation key to trigger the different control instructions corresponding to the mode information triggered by the selected desired mode.
When the mode information indicates a normal mode, the control instruction may be an instruction for displaying parking line, an instruction for stopping displaying a parking line, an instruction for switching to display a top-view reversing image, an instruction for switching to display a horizontal-view reversing image, or an instruction for switching to display an original reversing image. The instruction for displaying parking line, the instruction for stopping displaying a parking line, the instruction for switching to display a top-view reversing image, the instruction for switching to display a horizontal-view reversing image, and the instruction for switching to display an original reversing image can respectively correspond to the up arrow key, the down arrow key, the right arrow key, the left arrow key and the confirmation key, one by one. However, these examples are merely for exemplary illustration, and the application field of the present disclosure is not limited thereto.
When the mode information indicates a setting mode, the control instruction may be an up selection instruction, a down selection instruction, a right change instruction, a left change instruction, or a confirmation instruction, and the up selection instruction, the down selection instruction, the right change instruction, the left change instruction and the confirmation instruction can respectively correspond to the up arrow key, the down arrow key, the right arrow key, the left arrow key, and the confirmation key, one by one. However, these examples are merely for exemplary illustration, and the application field of the present disclosure is not limited thereto. The up selection instruction, the down selection instruction, the right change instruction, the left change instruction and the confirmation instruction are provided to the user for adjusting a location, a distance or a width of a reversing reference line displayed on the reversing image display device 10, or for operating functional options of an user interface of the reversing image display device 10 or switching option pages of the user interface. However, these examples are merely for exemplary illustration, and the application field of the present disclosure is not limited thereto.
When the mode information indicates a remark mode, the control instruction may be a parking line selection instruction, a view area adjustment instruction, a NTSC/PAL selection instruction, a fisheye/normal view selection instruction, or an image flip/normal selection instruction.
