Detailed Description
The detailed features and advantages of the present invention are described in detail in the following embodiments, which are sufficient for anyone skilled in the art to understand the technical contents of the present invention and to implement the present invention, and the related objects and advantages of the present invention can be easily understood by anyone skilled in the art from the disclosure, the claims and the drawings of the present specification. The following examples further illustrate aspects of the present invention in detail, but are not intended to limit the scope of the invention in any way.
Referring to fig. 1, an appearance schematic diagram of a display system capable of reducing noise according to an embodiment of the invention is shown. As shown in fig. 1, the display system capable of reducing noise includes a first radio 14 and a display device 3, and the display device 3 is electrically connected to the first radio 14.
The first radio 14 is disposed adjacent to the mouth of the user for receiving the sound signal emitted from the user. In practice, the first radio 14 is, for example, a Micro Electro Mechanical Systems (MEMS) microphone, and the first radio 14 is also a directional microphone having a sound receiving range of 15-60 degrees. Generally, the first radio 14 can be disposed adjacent to a headset, such as the headset 12 shown in fig. 1, so that the sound emitting portion of the user is as close as possible to the sound receiving end of the first radio 14. In practice, the earphone 12 is, for example, a headphone microphone (Headset)
Referring to fig. 1 and fig. 2 together, fig. 2 is a diagram illustrating an internal block architecture of a display device 3 according to an embodiment of the invention. The display device 3 comprises: a display panel 32, a second radio 34, a microprocessor 36, and a display controller 38.
The display panel 32 is used for displaying image signals. In practice, the display panel 32 includes, for example: a Twisted Nematic (TN) panel, an In-Plane-Switching (IPS) panel, or a Vertical Alignment (VA) panel, however, the hardware structure of the display panel 32 is not limited thereto.
the second radio 34 is disposed adjacent to one side of the display panel 32. For example, in fig. 1, the second radio receiver is disposed below the front side of the display panel 32. In practice, the second radio 34 is, for example, an Omni Directional (Omni Directional) microphone for receiving the ambient sound signal.
The microprocessor 36 is electrically connected to the first radio 14 and the second radio 34. In practice, after the first radio 14 and the second radio 34 receive the Sound signal and the environmental audio signal respectively, the Analog-to-Digital Converter (ADC) built in the microphone itself or the external ADC chip converts the Analog signals of the two audios into Digital signals, and then transmits the Digital Sound signals received by the first radio 14 and the second radio 34 to the microprocessor 36 through an I2S (Inter-IC Sound or Integrated Inter-chip Sound) interface or other audio transmission interfaces.
The microprocessor 36 is used for executing a noise reduction procedure according to the sound signal and the ambient audio signal to obtain a speech signal. In practice, the microprocessor 7 is, for example, an Integrated Circuit (IC), a microcontroller (MicroControl Unit) or a Digital Signal Processor (DSP), and the hardware structure of the microprocessor 7 is not particularly limited. The noise reduction procedure is to compare the sound signal received by the first radio 14 with the environmental audio signal received by the second radio 34 by digital signals, so as to retain the part of the sound signal belonging to the user's voice and filter the other part belonging to the environmental sound. In other words, the noise reduction program is that the microcontroller 36 calculates the characteristic waveform of the environmental audio signal recorded by the second radio 54, and subtracts the characteristic waveform belonging to the environmental audio signal from the characteristic waveform corresponding to the sound signal recorded by the first radio to obtain a pure voice signal without noise interference. The following will continue to describe the manner in which the speech signal obtained from the aforementioned noise reduction procedure is applied to another embodiment of the present invention.
In another embodiment of the display system with noise reduction function of the present invention, the microprocessor 36 is further configured to execute a voice recognition program according to the voice signal to obtain the voice command. In addition, the display panel 32 is described above for displaying the image signal, which may be the first image signal or the second image signal. The first video signal is herein referred to as a video signal transmitted from the host. The display controller 38 may set a default region in the range of the first image signal displayed on the display panel 32. The display controller 38 adjusts the first image signal to the second image signal according to a voice command obtained from the voice recognition program.
The "adjust to the second image signal" may be implemented as follows: the display controller 9 superimposes another partial image on the default region based on the original first image signal. For example, if the voice command is "brightness up", the display controller 38 presents the brightness state of the current display panel 32 in the default area in the form of an image or text, thereby informing the user that the display apparatus 3 has completed the adjustment action instructed by the user.
Another embodiment of the "adjusting to the second image signal" is: the display controller 38 makes the second image signal include an amplified image signal of the default region. For example, a game player often needs to enlarge and view a certain portion of a game screen during game playing so as to facilitate subsequent game operations. Referring to fig. 3A and 3B together, fig. 3A is a schematic diagram showing a shooting game picture from a first person perspective displayed on the display panel 32, wherein the shooting game picture includes four default regions D1-D4 separated by separation lines L1 and L2. When the player issues the voice command "zoom in the upper left corner", the voice command recognized by the microprocessor 36 can drive the display controller 38 to zoom in the first video signal belonging to the default region D1 into the second video signal, and the display controller 38 then presents the second video signal on the display panel 32, as shown in fig. 3B. In practice, the display controller 38 can control the display panel 32 to selectively present the first image signal or the second image signal, so as to determine the timing of switching the frames on the display panel 32. Through the display controller 38 based on the voice signal after noise reduction, the game player can aim at the shooting target more accurately, and the fun of the game is improved.
Please refer to fig. 4 and fig. 5 together. In another embodiment of the present invention, the display device 3 further has a light emitting module 39 electrically connected to the display controller 38, and the light emitting module 39 is used for selectively emitting a color light of a designated color according to a voice command. In practice, the Light Emitting module 39 is, for example, disposed on a Light Emitting Diode (LED) of the display device 3 opposite to the display panel 32, and the Light Emitting timing and the Light Emitting color thereof can be controlled by a voice command. Compared with the conventional display device 3 which is only used as an image output device, the display device 3 in the noise-reducing display system disclosed by the invention can be used as an input device for controlling peripheral light, so that the visual experience of a user when watching a screen is improved. In addition, compared with the conventional game host in which the light-emitting module 39 can only write the light configuration file by itself through the operation interface provided by the manufacturer for control, the voice command control method adopted by the display device 3 according to the embodiment of the present invention is more intuitive and simple in operation method, thereby reducing the burden of the user to learn various setting methods.
By means of the structure, the display system capable of reducing noise disclosed by the invention receives the sound emitted by the user and the ambient environment sound respectively by the directional microphone arranged near the mouth of the user and the omnidirectional microphone arranged on the display equipment, filters the environment sound in a digital signal processing mode through the microprocessor and eliminates the noise generated by a keyboard, a mouse and other people, so that other players or the sound control display equipment can receive clearer voice signals or voice instructions, and the fluency of the players in game is improved.
The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
