| titleOfInvention | Brightness detection method, camera control method, device, and medium |
| abstract | Embodiments of the present application provide a method for detecting brightness, a method for controlling a camera, a device, and a medium, wherein the method for detecting brightness uses a brightness detecting circuit to detect brightness, and the brightness detecting circuit includes: a photodiode, a switch, and at least two A detection group, the brightness detection method specifically includes: selecting a target detection group from at least two detection groups; connecting a control switch to the target detection group; performing voltage detection on the target detection group, and performing modulus-digital analysis on the voltage detection result. The analog-to-digital conversion corresponds to the number of sampling points; at least two detection groups include: a preset detection group, the preset detection group corresponds to a target brightness range, the target brightness range and the sampling point number The ratio meets the preset accuracy requirement; according to the digital voltage, the brightness detection result is determined. The embodiment of the present application can take into account both the preset accuracy requirement and the preset brightness range requirement while reducing the cost of brightness detection. |
