Abstract
Embodiments of this application provide a logarithmic curve generation method, a device, and a storage medium. The method includes: determining a dynamic range of a photosensitive element of a mobile device and a coding depth of the mobile device; obtaining a plurality of numerical points within the dynamic range, where each numerical point includes a stop within the dynamic range and a corresponding code value; and performing curve fitting based on the plurality of numerical points to obtain a log curve, where when the mobile device shoots in a log mode, the log curve is used to convert, into a code value, a raw signal that is output by the photosensitive element and that indicates brightness.
