[0090] In a possible implementation manner, the power consumption of the camera in the running state is determined according to the following manner:
[0091] Obtain the voltage V across the sampling resistor Rs when the camera is running i_d and V in_d , respectively calculate the current I in the operating state of the camera d and camera power consumption P d .
[0092] A possible implementation, according to the following formula to determine the remaining power P of the camera in the running state free :
[0093] P free =P max -P d
[0094] Among them, P max is the maximum power that the camera can output, P d It is the power consumption when the camera is running.
[0095] In a possible implementation manner, the target load may be a camera's fill light function and a function load that performs a specific function of the camera, and the camera's fill light function and the function load that performs a specific function respectively correspond to different op...

The invention relates to the technical field of camera images, in particular to a camera load starting method, device and equipment and a storage medium. The method is used for solving the problem ofcamera restart caused by sudden change of voltage when a camera fill-in light or other functional loads are turned on. According to the embodiment of the invention, the method comprises the steps: determining the residual power of a camera in an operation state according to the maximum power which can be outputted by the camera and the consumed power of the camera in the operation state; and whenit is determined that a target load needs to be started, if it is determined that an operation condition corresponding to the target load can be met according to the type of the target load and the residual power, starting the target load. According to the embodiment of the invention, judgment is carried out according to the real-time state of the camera and the operation condition of the target load, so that the problem of restarting of the camera due to sudden change of voltage which cannot be borne by the camera when the target load is started can be solved more stably, and the method has the advantages of real-time performance, higher adaptability and higher flexibility.
Description
technical field [0001] The present application mainly relates to the field of camera image technology, and in particular to a method, device, device and storage medium for starting a load of a camera. Background technique [0002] Currently, cameras are used in a wide range, but when the camera is powered by a long power cord, a low-voltage power adapter or a centralized power supply, etc., it often leads to insufficient power supply at the camera end. Once the camera turns on a high-power load, the voltage will be reduced. If it is further reduced, the camera will be powered off and restarted, which will affect the user's use. [0003] In the current existing technology, when it is necessary to turn on the camera fill light or other functional loads, detect and judge whether the power supply voltage of the camera meets the voltage threshold condition, and if the power supply voltage meets the voltage threshold, turn on the camera fill light or other functional loads , beca...
