Embodiment approach

[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...

Abstract

The present invention relates to the technical field of camera images, in particular to a camera load starting method, equipment, device and storage medium. It is used to solve the problem of restarting the camera caused by sudden voltage changes when the camera fill light or other functional loads are turned on. In the embodiment of the present invention, the remaining power of the camera in the running state is determined according to the maximum output power of the camera and the power consumption of the camera in the running state; If the type and the remaining power are determined to meet the operating conditions corresponding to the target load, then the target load is turned on. Since the embodiment of the present invention judges according to the real-time state of the camera and the operating conditions of the target load, it can more stably solve the problem of restarting the camera caused by the sudden voltage change that the camera cannot bear when the target load is turned on, and has real-time performance and better adaptability. Stronger and more flexible.

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...
