The control system and the control method in the present invention will be further described in detail below with reference to the accompanying drawings.

Please refer to FIG. 1 , which is a schematic diagram of functional modules of an electronic device 100 according to a preferred embodiment of the present invention. The electronic device 100 is capable of receiving light of different colors emitted by the light emitting unit 200 and performing different functions according to the received light of different colors. In this embodiment, the light emitting unit 200 may include a plurality of light sources, each of which emits light of a different color, wherein the light source may be a laser light source or an LED light. In other embodiments, the light emitting unit 200 may also be a structure including a white light source and different color filters, and the light emitting unit 200 may emit light of different colors by adjusting the filter. In the present embodiment, the light emitting unit 200 is capable of emitting light of three colors of red, green, and blue.

In the present embodiment, the electronic device 100 includes a photosensitive unit 10, a storage unit 20, and a control unit 30.

The photosensitive unit 10 is configured to receive light of different colors emitted by the light emitting unit 200, and convert the received optical signals of different colors into corresponding electrical signals. In the embodiment, the photosensitive unit 10 is a color sensitive detector. When incident light is incident on the color sensitive detector, the output current of the color sensitive detector changes according to the change of the wavelength of the incident light. For example, when the color sensitive detector receives red light, the output current is 0.1A; when green light is received, the output current is 0.2A; when blue light is received, the output current is 0.3A. In the present embodiment, the photosensitive unit 10 is a color recognition sensor TCS230D. In the present embodiment, the photosensitive unit 10 includes a color sensitive detector that receives a light beam of one color emitted by the light emitting unit 200 each time. In other embodiments, the light emitting unit 200 can simultaneously emit a plurality of light beams of different colors, and the photosensitive unit 10 includes a plurality of color sensitive sensors, each color sensor receiving a light beam of one color, so that the photosensitive unit 10 can At the same time, a plurality of different colors of light are received and the plurality of colors of light are converted into corresponding electrical signals to achieve a combined operation of multiple functions.

The storage unit 20 is configured to store a correspondence table between different electrical signals and control instructions of the electronic device. For example, as shown in FIG. 2, when the electronic device 100 is a projection device capable of performing a PPT document presentation function, the current is 0.1. The control command corresponding to the electrical signal of A is the operation of the next page, the control command corresponding to the electrical signal with the current of 0.2A is the execution of the previous page operation, and the control command corresponding to the electrical signal with the current of 0.3A is the execution of the brush operation.

The control unit 30 is configured to acquire an electrical signal generated by the photosensitive unit 10, and determine a control instruction corresponding to the acquired electrical signal according to a correspondence table between the electrical signal stored in the storage unit 20 and the electronic device control command, and The electronic device 100 is controlled to execute a function corresponding to the control command. For example, after the photosensitive unit 10 in the projection device receives the red light and converts the red light signal into an electrical signal of 0.1 A current, the control unit 30 determines the function corresponding to the electrical signal according to the relationship table stored in the storage unit 20. To perform the next page operation, the control unit 30 controls the projection device to perform the conversion of the PPT presentation to the next page.

3 is a flow chart of a method of controlling an electronic device according to an embodiment of the present invention.

Step S301: The photosensitive unit 10 receives light of different colors emitted by the light emitting unit 200.

Step S302: The photosensitive unit 10 converts the received optical signals of different colors into corresponding electrical signals.

Step S303: The control unit 30 acquires an electrical signal generated by the photosensitive unit 10, and determines a control command corresponding to the acquired electrical signal according to a correspondence table between the electrical signal stored in the storage unit 20 and the electronic device control command.

Step S304: The control unit 30 controls the electronic device 100 to execute a function corresponding to the control instruction.
