Control Method, Control Device, Mobile Terminal, and Computer-Readable Storage Medium

A control device for controlling an imaging device, the control device comprising:

• at least one processor;
• and
• a computer readable storage medium, coupled to the at least one processor and storing at least one computer executable instructions which, when being executed by the at least one processor, cause the at least one processor to carry out following program modules:
• a judgment module, configured to process a cached image output by the imaging device to identify whether there is an overexposed area in the cached image;
• an acquisition module, configured to acquire, in a case where there is the overexposed area in the cached image, an RGB channel value of a surrounding area around the overexposed area;
• and
• a first processing module, configured to perform white balance processing on the cached image according to the RGB channel value.

A mobile terminal, comprising a housing, a processor, a memory, a circuit board, a power circuit and an imaging device, wherein the circuit board is disposed inside a space enclosed by the housing, and the processor and the memory are disposed on the circuit board;

• the power circuit is configured to supply power to various circuits or devices of an electronic device;
• the memory is configured to store executable program codes;
• and the processor runs programs corresponding to the executable program codes by reading the executable program codes stored in the memory to perform the following operations:
• processing a cached image output by the imaging device to identify whether there is an overexposed area in the cached image;
• acquiring, in a case where there is the overexposed area in the cached image, an RGB channel value of a surrounding area around the overexposed area;
• and
• performing white balance processing on the cached image according to the RGB channel value.
