The control module 110 includes a normal power consumption state and a low power consumption state. When the control module 110 works in a normal power consumption state, the normal power consumption output end outputs a high level signal, and at the same time, the low power consumption output end outputs a low level signal; when the control module 110 operates in the low power consumption state, the low power consumption output terminal outputs a high level signal, and at this time, the normal power consumption output terminal outputs a low level signal.
When the normal power consumption output terminal of the control module 110 outputs a high level signal, the first output terminal and the second output terminal of the delay module 140 output a low level signal; when the normal power consumption output end of the control module 110 is switched from outputting a high level signal to outputting a low level signal, the first output end and the second output end of the delay module 140 output a low level signal within the delay time, and output a high level signal after the delay time is over.
When the first output end and the second output end of the delay module 140 output low level signals, the trigger module 120 is in a stop state, and the photographing module 130 is in a working state; when the first output terminal and the second output terminal of the delay module 140 output high level signals, the trigger module 120 is in a working state, and the photographing module 130 is in a stop state.
When the trigger module 120 is in a stop state, the trigger module 120 cannot be triggered; when the trigger module 120 is in the working state, the trigger module 120 can be triggered.
When the photographing module 130 is in a stopped state, the photographing module 130 cannot take a picture; when the photographing module 130 is in an operating state, the photographing module 130 can be controlled by the control module 110.

In the process of controlling the photographing module 130 to photograph by the control module 110, after the photographing module 130 finishes photographing, the control module 110 is switched from the normal power consumption state to the low power consumption state, when the control module 110 works in the low power consumption state, the control module 110 cannot control the photographing module 130, and at this time, no matter the photographing module 130 is in the working state or in the stop state, photographing cannot be performed.
Based on this, it can be understood that, in the photographing circuit, when the control module 110 operates in the normal power consumption state, the normal power consumption output terminal of the control module 110 outputs a high level signal, so that the first output terminal and the second output terminal of the delay module 140 output low level signals, when the first output terminal of the delay module 140 outputs a low level signal, the delay module 140 controls the trigger module 120 to be in the stop state that cannot be triggered, when the second output terminal of the delay module 140 outputs a low level signal, the delay module 140 controls the photographing module 130 to enter the operating state, at this time, the control module 110 controls the photographing module 130 to photograph through the first control terminal, after the photographing module 130 finishes photographing, the control module 110 is switched from the normal power consumption state to the low power consumption state, and the normal power consumption output terminal of the control module 110 is switched from outputting a high level signal to outputting a low level signal, the delay module 140 is triggered to delay, so that the first output terminal and the second output terminal of the delay module 140 output low level signals within the delay time, when the first output terminal of the delay module 140 outputs a low level signal, the delay module 140 controls the trigger module 120 to maintain a stop state within the delay time, when the second output terminal of the delay module 140 outputs a low level signal, the delay module 140 controls the photographing module 130 to maintain a working state within the delay time, at this time, because the control module 110 works in a low power consumption state, the control module 110 cannot control the photographing module 130 to photograph, after the delay time is over, the first output terminal and the second output terminal of the delay module 140 output high level signals, when the first output terminal of the delay module 140 outputs a high level signal, the delay module 140 controls the trigger module 120 to enter a working state, when the second output terminal of the delay module 140 outputs a high level signal, the delay module 140 controls the photographing module 130 to be in a stop state, at this time, the triggering module 120 can be triggered, and if the triggering module 120 is triggered, the control module 110 is switched from a low power consumption state to a normal power consumption state; if the triggering module 120 is not triggered, the control module 110 still operates in a low power consumption state.
It can be understood that, during the delay time, the control module 110 operates in the low power consumption state, and under the condition that the trigger module 120 cannot be triggered, the control module 110 cannot be switched from the low power consumption state to the normal power consumption state, so that the control module 110 can maintain the low power consumption state within the delay time, avoid being in the normal power consumption state for a long time, and reduce power consumption.

The control module 110 includes a normal power consumption state and a low power consumption state. When the control module 110 works in a normal power consumption state, the normal power consumption output end outputs a high level signal; when the control module 110 operates in a low power consumption state, the normal power consumption output terminal outputs a low level signal.
When the normal power consumption output terminal of the control module 110 outputs a high level signal, the first output terminal and the second output terminal of the delay module 140 output a low level signal; when the normal power consumption output end of the control module 110 is switched from outputting a high level signal to outputting a low level signal, the first output end and the second output end of the delay module 140 output a low level signal within the delay time, and output a high level signal after the delay time is over.
When the first output end and the second output end of the delay module 140 output low level signals, the trigger module 120 is in a stop state, and the photographing module 130 is in a working state; when the first output terminal and the second output terminal of the delay module 140 output high level signals, the trigger module 120 is in a working state, and the photographing module 130 is in a stop state.
When the trigger module 120 is in a stop state, the trigger module 120 cannot be triggered; when the trigger module 120 is in the working state, the trigger module 120 can be triggered.
When the photographing module 130 is in a stopped state, the photographing module 130 cannot take a picture; when the photographing module 130 is in an operating state, the photographing module 130 can be controlled by the control module 110.

In the process of controlling the photographing module 130 to photograph by the control module 110, after the photographing module 130 finishes photographing, the control module 110 is switched from the normal power consumption state to the low power consumption state, when the control module 110 works in the low power consumption state, the control module 110 cannot control the photographing module 130, and at this time, no matter the photographing module 130 is in the working state or in the stop state, photographing cannot be performed.
Based on this, it can be understood that, in the photographing circuit, when the control module 110 operates in the normal power consumption state, the normal power consumption output terminal of the control module 110 outputs a high level signal, so that the first output terminal and the second output terminal of the delay module 140 output low level signals, when the first output terminal of the delay module 140 outputs a low level signal, the delay module 140 controls the trigger module 120 to be in the stop state that cannot be triggered, when the second output terminal of the delay module 140 outputs a low level signal, the delay module 140 controls the photographing module 130 to enter the operating state, at this time, the control module 110 controls the photographing module 130 to photograph through the first control terminal, after the photographing module 130 finishes photographing, the control module 110 is switched from the normal power consumption state to the low power consumption state, and the normal power consumption output terminal of the control module 110 is switched from outputting a high level signal to outputting a low level signal, the delay module 140 is triggered to delay, so that the first output terminal and the second output terminal of the delay module 140 output low level signals within the delay time, when the first output terminal of the delay module 140 outputs a low level signal, the delay module 140 controls the trigger module 120 to maintain a stop state within the delay time, when the second output terminal of the delay module 140 outputs a low level signal, the delay module 140 controls the photographing module 130 to maintain a working state within the delay time, at this time, because the control module 110 works in a low power consumption state, the control module 110 cannot control the photographing module 130 to photograph, after the delay time is over, the first output terminal and the second output terminal of the delay module 140 output high level signals, when the first output terminal of the delay module 140 outputs a high level signal, the delay module 140 controls the trigger module 120 to enter a working state, when the second output terminal of the delay module 140 outputs a high level signal, the delay module 140 controls the photographing module 130 to be in a stop state, at this time, the triggering module 120 can be triggered, and if the triggering module 120 is triggered, the control module 110 is switched from a low power consumption state to a normal power consumption state; if the triggering module 120 is not triggered, the control module 110 still operates in a low power consumption state.
