Description
Technical Field
The present invention relates to a method and an electronic device, and more particularly, to a method for pairing a projection device by an external remote control device and a projection device using the same.
Background
At present, projectors on the market usually adopt an infrared remote controller to implement remote control, but most users only use the function of turning on and off the projector, and the frequency of using other functions such as language or projection mode is not high. When a user needs a projector, the user needs to use a plurality of different remote controllers to pair devices including the projector, a screen or an image source device. The above process is rather cumbersome for the user.
In order to reduce the number of remote controllers required by a user, some of the remote controllers on the market have a learning function. The remote controller having the learning function may copy an infrared code (IR code) of other remote controllers. The remote controller with the infrared codes of other remote controllers copied can achieve the purpose of one-to-many control. However, there is often a difference between the copied infrared code and the original infrared code, and problems such as insensitivity to remote control or reduction in control distance are often caused. In addition, compared with a general remote controller, the remote controller with the learning function has higher cost and fewer models.
The background of the invention is provided to aid in understanding the present disclosure, and thus, the disclosure in the background section may include other art that does not constitute prior art that is known to those skilled in the art. The statements in the "background" section do not represent that matter or the problems which may be solved by one or more embodiments of the present invention, but are known or appreciated by those skilled in the art before filing the present application.

The invention discloses a method for pairing a projection device through an external remote control device, which is used for the projection device. The method comprises the following steps: generating a trigger signal in response to a first operation; receiving a first signal in response to a trigger signal; decoding the first signal to generate a decoding result; responding to the second operation and corresponding the decoding result to at least one function of the projection device; and receiving the second signal and performing at least one function in response to the second signal matching the decoding result.
Based on the above, the projection apparatus of the present invention can adapt to various remote controllers through the learning function.

Detailed Description
Fig. 1 is a schematic diagram illustrating a projection apparatus 100 and a remote control device 160 according to an embodiment of the invention. The projection apparatus 100 includes a processor 110, a storage medium 120, a receiver 130, a human-machine interface 140, and a projection module 150.
The processor 110 is, for example, a Central Processing Unit (CPU), or other programmable general purpose or special purpose Micro Control Unit (MCU), a microprocessor (microprocessor), a Digital Signal Processor (DSP), a programmable controller, an Application Specific Integrated Circuit (ASIC), a Graphics Processing Unit (GPU), a video signal processor (ISP), a video processing unit (IPU), an Arithmetic Logic Unit (ALU), a Complex Programmable Logic Device (CPLD), a Field Programmable Gate Array (FPGA), or other similar devices or combinations thereof. The processor 110 may be coupled to the storage medium 120, the receiver 130, the human-machine interface 140, and the projection module 150.
The storage medium 120 is, for example, any type of fixed or removable Random Access Memory (RAM), read-only memory (ROM), flash memory (flash memory), Hard Disk Drive (HDD), Solid State Drive (SSD), or the like or a combination thereof, and is used for storing a plurality of modules or various applications executable by the processor 110.
The receiver 130 receives signals in a wireless or wired manner. Receiver 130 may also perform operations such as low noise amplification, impedance matching, mixing, up or down frequency conversion, filtering, amplification, and the like. In one embodiment, the receiver 130 is, for example, but not limited to, an infrared receiver.
The human-machine interface 140 has output and input functions. For example, the human-machine interface 140 may include keys or a touch screen. The human-machine interface 140 may receive the operation of the user through a key or a touch screen, and output a control signal corresponding to the operation of the user to the processor 110, so that the processor 110 executes a function corresponding to the operation. For another example, the human-machine interface 140 may also include a display. The human-machine interface 140 may display, for example, an OSD (on-screen display) menu to the user through a display.
The projection module 150 can project the image received from the processor 110. In one embodiment, the projection module 150 may include, but is not limited to, a light source module, a light valve module, or a projection lens. The light source module can provide an illumination beam to the light valve module. The light valve module is, for example, an optical modulation device of a Digital Micromirror Device (DMD), a reflective Liquid Crystal On Silicon (LCOS) or a Liquid Crystal Panel (transmissive Liquid Crystal Panel), and is used for converting the illumination beam into an image beam to be provided to the projection lens. The projection lens can be used to convert the image beam into a projection beam projected to the outside, so that the projection apparatus 100 achieves a projection operation.
Fig. 2 is a flowchart illustrating a method for pairing the projection apparatus 100 with an external remote control device according to an embodiment of the invention.
In step S201, the human-machine interface 140 may generate a trigger signal in response to a first operation (e.g., an operation from a user), for example, the first operation may be pressing a key of a learning function on the human-machine interface 140, and the trigger signal may be used to enable the learning function of the projection apparatus 100. For example, the human-computer interface 140 may display an OSD menu, and the user may enable the learning function of the projection apparatus 100 by clicking a function key corresponding to the learning function in the OSD menu.
In step S202, the processor 110 may receive a first signal through the receiver 130 in response to the trigger signal. Specifically, after the learning function of the projection apparatus 100 is enabled by the trigger signal, the processor 110 may turn on the receiving function of the receiver 130 according to the trigger signal, so as to receive the first signal through the receiver 130. In the present embodiment, the first signal is, for example, an infrared signal transmitted from the remote control device 160, but the present invention is not limited thereto. Further, the first signal may include one or more instructions corresponding to remote control device 160. For example, the first signal may be, for example, an instruction corresponding to a key of the remote control device 160. For example, the first signal may be a combination of a plurality of commands respectively corresponding to a plurality of keys of the remote control device 160.
After the first signal is input to the processor 110, in step S203, the processor 110 may decode the first signal to generate a decoding result, where the decoding result may include a key combination corresponding to the first signal, for example, if the user presses the power key of the remote control device 160, the processor 110 may know that the key pressed by the user is the power key after decoding the infrared signal (the first signal) corresponding to the power key.
In step S204, the processor 110 may receive the third signal through the receiver 130 after generating the decoding result. In the present embodiment, the third signal is, for example, an infrared signal transmitted from the remote control device 160, but the present invention is not limited thereto. Further, the third signal may include one or more instructions corresponding to remote control device 160. For example, the third signal may be, for example, an instruction corresponding to a key of the remote control device 160. For another example, the third signal may be a combination of a plurality of commands respectively corresponding to a plurality of keys of the remote control device 160.
In one embodiment, processor 110 may prompt the user to operate remote control device 160 via human-machine interface 140 to send a third signal identical to the first signal.
In step S205, the processor 110 may decode the third signal to generate a second decoding result, where the second decoding result may include an infrared code generated after the third signal is decoded. In an embodiment, after generating the decoding result corresponding to the third signal, the processor 110 may prompt the user to operate the human-machine interface 140 through the human-machine interface 140. The human-machine interface 140 may receive a second operation (e.g., an operation from a user) to correspond the decoding result to at least one function of the projection apparatus 100 corresponding to the second operation.
In step S206, the processor 110 compares the decoding result (i.e., the decoding result generated in step S203) with the second decoding result (i.e., the second decoding result generated in step S205). If the decoding result matches the second decoding result, the process proceeds to step S208. If the decoding result does not match the second decoding result, the process proceeds to step S207.
In step S207, the processor 110 may determine that the decoding result is erroneous. In one embodiment, the processor 110 may prompt the user through the hmi 140 that the decoding result is incorrect. In other words, the execution of the learning function of the projection apparatus 100 fails. The user needs to perform the learning function of the projection apparatus 100 again.
In step S208, the processor 110 may map the decoding result to at least one function of the projection apparatus 100, wherein the at least one function may correspond to the second operation in step S203 or step S205. The storage medium 120 may store the decoding result. The storage medium 120 may further store a corresponding relationship between the operation and the at least one function.
In an embodiment, after the decoding result corresponding to the first signal is generated in step S203, the processor 110 may prompt the user to operate the human-machine interface 140 through the human-machine interface 140. The human-machine interface 140 may receive a second operation (e.g., an operation from a user) to correspond the decoding result to at least one function of the projection apparatus 100 corresponding to the second operation, for example, the user may select the decoding result as the at least one function of the projection apparatus 100.
The at least one function may include, but is not limited to, turning on power, turning off power, adjusting volume, selecting signal sources, keystone correction, or adjusting image parameters. For example, the user can operate the human-machine interface 140 to correspond the decoding result to the function of turning on the power of the projection apparatus 100. Later, if the decoding result of the signal received by the processor 110 through the receiver 130 matches the decoding result corresponding to the power-on function, the processor 110 may perform the power-on function according to the received signal.
In the above steps, the function that the user has set the function incorrectly can be avoided, the user can prompt the user to set the function first after step S203, and the user can set the function again in step S205, and the processor 110 can verify whether the two set functions are the same, so as to ensure that the user sets the correct function.
Since the projection apparatus 100 learns the command of the remote control apparatus 160, the signal transmitted by the remote control apparatus 160 may be distorted due to the influence of noise. In order to ensure that the decoded result of the projection apparatus 100 matches the signal transmitted by the remote control device 160, the projection apparatus 100 of the present invention may ask the user to transmit the same two signals through the remote control device 160. If the two signals match, the projection apparatus 100 corresponds the decoding result associated with the two signals to at least one function of the projection apparatus 100. If the two signals do not match, it represents that at least one of the two signals may be distorted by noise. Therefore, the projection apparatus 100 does not correspond the decoding results associated with the two signals to at least one function of the projection apparatus 100.
Fig. 3 is a flowchart illustrating a method for controlling the projection apparatus 100 via the remote control device 160 according to an embodiment of the invention. After the projection apparatus 100 corresponds the decoding result of the first signal from the remote control device 160 to at least one function of the projection apparatus 100, the user can send a second signal associated with the first signal through the remote control device 160 to trigger the projection apparatus 100 to execute the at least one function. Specifically, in step S301, the processor 110 may receive a second signal from the remote control device 160 through the receiver 130. In step S302, the processor 110 may perform at least one function corresponding to the first signal in response to the second signal matching the decoding result corresponding to the first signal.
In summary, the projection apparatus of the present invention can be adapted to various remote controllers through the learning function. The user can start the learning mode of the projection device through the human-computer interface of the projection device. During the learning process, the projection device can receive a signal from an external remote control device and correspond the signal to the function of the projection device. Then, if the projection device receives the same signal as the signal, the projection device can execute the corresponding function according to the signal. Therefore, the effect of one-to-many control by using an external remote control device can be realized, and the number of remote controllers required to be operated by a user is reduced. On the other hand, the conventional projection apparatus can implement the method of the present invention by software/firmware update without adding additional hardware components. Therefore, the method of the invention does not increase the cost of the projection device.
