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.

Abstract: Embodiments of this application relate to the technical field of video shooting, and provide a video processing method and apparatus, an electronic device, and a storage medium. The video processing method includes: determining one video style template among a plurality of video style templates, where each video style template is corresponding to a preset look up table LUT; obtaining a video shot through a camera lens; processing the video shot through the camera lens by using a logarithm LOG curve corresponding to a current photosensitivity ISO of the camera lens, to obtain a LOG video; and processing the LOG video based on a LUT corresponding to the determined video style template, to obtain a video corresponding to the determined video style template.
