Abstract
Provided in the embodiments of the present application are a brightness measurement method and apparatus, a control method and apparatus for a photographic apparatus, and a medium. In the brightness measurement method, a brightness measurement circuit is used to perform brightness measurement, the brightness measurement circuit comprising: a photosensitive diode, a switch and at least two measurement groups. The brightness measurement method specifically comprises: selecting a target measurement group from among at least two measurement groups; controlling a switch to connect to the target measurement group; performing voltage measurement on the target measurement group, and performing analog-to-digital conversion on the voltage measurement result to obtain a digital voltage, wherein the analog-to-digital conversion corresponds to the number of sampling points, the at least two measurement groups comprise a preset measurement group, the preset measurement group corresponds to a target brightness range, and the ratio of the target brightness range to the number of sampling points meets a preset precision requirement; and determining a brightness measurement result according to the digital voltage.
