Time-lapse photographing control method and apparatus, readable storage medium, and camera
Embodiments of the disclosure provide a method, an apparatus, and a readable storage medium for controlling a time-lapse photographing. The method includes detecting whether a time-lapse photographing session has ended; determining a time of a next turning-on of the camera in response to the detection that the session has not ended, the time of the next turning-on of the camera being earlier than a time of a next photographing event, the time of the next photographing event being a sum of a time of a current photographing event and a time interval between photographing events; configuring a real time clock based on the time of the next turning-on of the camera; shutting down the camera; starting up the camera when the time of the next turning-on of the camera is reached; and taking a photograph when the time of the next photographing event is reached.
1. A method for controlling time-lapse photographing, comprising:
detecting whether a time-lapse photographing session has ended;
determining a time of a next turning-on of the camera in response to the detection that the time-lapse photographing session has not ended, the time of the next turning-on of the camera being earlier than a time of a next photographing event, the time of the next photographing event being a sum of a time of a current photographing event and a time interval between photographing events;
configuring a real time clock based on the time of the next turning-on of the camera;
obtaining the time of the next photographing event according to the time of the current photographing event and the time interval between photographing events;
determining a Cyclic Redundancy Check (CRC) value for data of the time of the next photographing event;
saving the data of the time of the next photographing event and the CRC value to a non-volatile storage device;
shutting down the camera;
starting up the camera when the time of the next turning-on of the camera is reached according to the real time clock;
reading the data of the time of the next photographing event from the non-volatile storage device;
determining a CRC check code for the data the time of the next photographing event;
if the CRC check code is consistent with the CRC value, using the saved data of the time of the next photographing event as the time of the next photographing event; and
when the time of the next photographing event is reached, taking the photograph.
2. The method according to claim 1 , wherein determining the time of the next turning-on of the camera further comprises:
determining, as the time of the next turning-on of the camera, a difference between the time of the next photographing event and a pre-turning-on time value.
3. The method according to claim 1 , further comprising:
obtaining the time of the next photographing event according to the time of the current photographing event and the time interval between photographing events.
4. A time-lapse photographing control apparatus, comprising:
a memory configured to store a set of instructions; and
a processor configured to execute the set of instruction to cause the apparatus to:
detect whether a time-lapse photographing session has ended;
determine a time of a next turning-on of the camera in response to the detection that the time-lapse photographing session has not ended, the time of the next turning-on of the camera being earlier than a time of a next photographing event, the time of the next photographing event being a sum of a time of a current photographing event and a time interval between photographing events;
configure a real time clock based on the time of the next turning-on of the camera;
obtain the time of the next photographing event according to the time of the current photographing event and the time interval between photographing events;
determine a Cyclic Redundancy Check (CRC) value for data of the time of the next photographing event;
save the data of the time of the next photographing event and the CRC value to a non-volatile storage device;
shut down the camera;
start up the camera when the time of the next turning-on of the camera is reached according to the real time clock;
read the data of the time of the next photographing event from the non-volatile storage device;
determine a CRC check code for the data the time of the next photographing event;
if the CRC check code is consistent with the CRC value, use the saved data of the time of the next photographing event as the time of the next photographing event; and
when the time of the next photographing event is reached, take the photograph.
5. The apparatus according to claim 4 , wherein the processor is further configured to execute the set of instruction to cause the apparatus to determine the time of the next turning-on of the camera by:
determining, as the time of the next turning-on of the camera, a difference between the time of the next photographing event and a pre-turning-on time value.
6. The apparatus according to claim 4 , wherein the processor is further configured to execute the set of instruction to cause the apparatus to:
obtain the time of the next photographing event according to the time of the current photographing event and the time interval between photographing events.
7. A non-transitory computer readable storage medium that stores a set of instructions, when executed by at least one processor of an electronic device, cause the electronic device to perform a method for controlling a time-lapse photographing, the method comprising:
detecting whether a time-lapse photographing session has ended;
determining a time of a next turning-on of the camera in response to the detection that the time-lapse photographing session has not ended, the time of the next turning-on of the camera being earlier than a time of a next photographing event, the time of the next photographing event being a sum of a time of a current photographing event and a time interval between photographing events;
configuring a real time clock based on the time of the next turning-on of the camera;
obtaining the time of the next photographing event according to the time of the current photographing event and the time interval between photographing events;
determining a Cyclic Redundancy Check (CRC) value for data of the time of the next photographing event;
saving the data of the time of the next photographing event and the CRC value to a non-volatile storage device;
shutting down the camera;
starting up the camera when the time of the next turning-on of the camera is reached according to the real time clock;
reading the data of the time of the next photographing event from the non-volatile storage device;
determining a CRC check code for the data the time of the next photographing event;
if the CRC check code is consistent with the CRC value, using the saved data of the time of the next photographing event as the time of the next photographing event; and
when the time of the next photographing event is reached, taking the photograph.
