Method for performing adaptive frame rate adjustment in electronic device for enhancing scene experience, and associated apparatus

An electronic device, for performing adaptive frame rate adjustment in the electronic device for enhancing scene experience, the electronic device comprising:

• a processing circuit, arranged to control operations of the electronic device;
• and
• a display, coupled to the processing circuit, arranged to display information for the electronic device;
• wherein:
• the electronic device is arranged to utilize the processing circuit to determine whether at least one predetermined activation criterion regarding the adaptive frame rate adjustment is satisfied to generate at least one determination result, for selectively changing a frame rate of an input frame source within the electronic device according to the at least one determination result, wherein the at least one determination result indicates whether the at least one predetermined activation criterion is satisfied;
• in response to the at least one determination result indicating that the at least one predetermined activation criterion is satisfied, the electronic device is arranged to utilize the processing circuit to change the frame rate of the input frame source, for obtaining multiple input frames from the input frame source within a predetermined time limit;
• and
• the electronic device is arranged to utilize the processing circuit to perform image processing of a visual effect according to the multiple input frames to generate at least one output frame having the visual effect, for being displayed by the display under control of the processing circuit.
