As shown in fig. 1 and 2, the present invention provides a terminal apparatus and a preferred embodiment of a control method thereof.
The terminal device 100 includes a display 130, and the control method includes:
step S11, establishing a communication connection with the external control device 200;
step S12, if the trigger signal is received, the shooting mode is performed, and the display screen 130 is controlled to display the shooting interface 131.
Specifically, the terminal device 100 establishes a communication connection with an external control device 200, the control device 200 can directly send control information to the terminal device 100, and the terminal device 100 performs corresponding operations according to the control information and referring to a corresponding instruction database or according to the content of the control information, so as to realize the shooting operation of the terminal device 100. The terminal device 100 is in a standby (black screen, lock screen) state, a main interface state, and other software interface states during the waiting period, enters a shooting mode if receiving a trigger signal, and controls the display screen 130 to switch from the above states (in the standby (black screen, lock screen) state, the main interface state, and other software interface states) and enter the shooting interface 131 to perform corresponding shooting operation.
For example, the terminal device 100 is in a black screen state during the waiting period, and lights up the screen and enters the shooting interface 131 if receiving the trigger signal; for another example, the terminal device 100 is in the state of another software interface while waiting, and switches back to the home interface and then enters the imaging interface 131, or directly switches to the imaging interface 131.
In the present embodiment, a preferred solution of the terminal device 100 is provided, and refer to fig. 2.
The terminal device 100 includes a first control unit 110, a display 130 and a first communication unit 120, wherein the first control unit 110 is connected to the display 130 and the first communication unit 120 respectively, and stores a computer program, and the computer program can implement the control method; the first control unit 110 establishes a communication connection with an external control device 200 through the first communication unit 120, and receives a trigger signal; the first control unit 110 performs a shooting mode after receiving the trigger signal, and controls the display screen 130 to display a shooting interface 131.
Specifically, the first control unit 110 is a main control center of the terminal device 100, and may also be a control center for controlling the photographing function, and controls or calls a driver of the display screen 130 to control the display of the display screen 130, for example, when the first control unit 110 enters the photographing mode, the display screen 130 is controlled to display the photographing interface 131; meanwhile, the first control unit 110 is a main control center of the terminal device 100, and may also be a control center for controlling a connection function, and controls or calls a driver of the first communication unit 120 to control the first communication unit 120, so as to transmit data and implement communication with the external control device 200.
The first control unit 110 may be a chip or a logic circuit, and if the chip is a chip, the chip is used as a main control module or a functional module of the terminal device 100 to implement the operation of the terminal device 100, or the chip may be a logic circuit, and cooperates with the main control chip of the terminal device 100 to implement the required functions, such as driving the display 130 and the first communication unit 120 to work, so as to implement the control method.
In this embodiment, two control schemes based on the trigger signal are provided.
In the first scheme, the trigger signal comprises a one-key starting signal.
The control method of the terminal device 100 has two major steps: firstly, the control device 200 wakes up the terminal device 100 by a one-key start signal to enable the terminal device 100 to enter a shooting mode, and controls the display screen 130 to display a shooting interface 131; second, the terminal device 100 waits for a control command of the control device 200, for example, a control signal of the photographing interface 131, to perform a related function operation in the photographing mode. The advantage of this solution is that it prevents malfunction, and only sends a one-touch activation signal to "wake up" the terminal device 100.
And in the second scheme, the trigger signal comprises a key starting signal or/and at least one shooting interface 131 control signal.
In this embodiment, the control method further includes:
step S121, if a one-key starting signal is received, a shooting mode is carried out, and the display screen 130 is controlled to display a shooting interface 131;
step S122, if receiving the control signal of the shooting interface 131, performing a shooting mode, and controlling the display screen 130 to display the shooting interface 131;
the control signal of the shooting interface 131 includes one or more of a shooting signal, a camera switching signal, a shooting mode switching signal, a focal length enlarging signal and a focal length reducing signal. Wherein, step S121 and step S122 are not sequentially divided.
The difference from the first scheme is that the first step of the first scheme may be that the terminal device 100 may perform the shooting mode after receiving the one-key start signal, or may be that the terminal device 100 may perform the shooting mode after receiving the control signal of the shooting interface 131. The advantage of this solution is that it is not necessary to specially send a key start signal, and the terminal device 100 can enter the shooting mode only by connecting the control device 200 and sending the trigger signal to the terminal device 100, which is convenient to use. Of course, the terminal device 100 may be set to the shooting mode by controlling a signal as the start signal through the shooting interface 131 without providing the one-key start signal.
In this embodiment, the terminal device 100 establishes a bluetooth communication connection with an external control device 200; certainly, other communication connection modes can also be, like WIFI, shortwave etc. can realize terminal device 100 with outside controlling means 200's communication connection can, the bluetooth is all stronger than price/performance ratio, stability comparatively speaking.
