Abstract: This application provides a frequency scaling method. The method includes: predicting an energy efficiency parameter for processing a current frame of an image by at least one module; and selecting, from a plurality of frequency sets based on the predicted energy efficiency parameter, a first frequency set that meets an energy efficiency requirement, and scaling a working frequency of each of the at least one module for processing the current frame to a preset frequency corresponding to each of the at least one module. According to the technical solutions provided in the embodiments of this application, a load change requirement can be responded to in time in a frequency scaling process.
