Image generation method and device

An electronic device, comprises:

• a housing, a processor, a memory, a circuit board and a power supply circuit, wherein, the circuit board is arranged inside a space enclosed by the housing, the processor and the memory are arranged on the circuit board;
• the power supply circuit is configured to supply power for various circuits or elements of the electronic device;
• the memory is configured to store executable program codes, and the processor executes a program corresponding to the executable program codes by reading the executable program codes stored in the memory so as to perform:
• receiving a screenshot instruction;
• generating a plurality of layers corresponding to the screenshot instruction, storing image content in a screen region selected by a user into a plurality of storage areas corresponding to the generated layers, and displaying, on the generated layers, the image content in the screen region selected by the user, wherein, the plurality of storage areas corresponding to the generated layers are independent of a storage area corresponding to a layer, which is in an unclosed state, generated according to a previously received screenshot instruction;
• and
• after receiving an image generation instruction for at least one layer currently in the unclosed state, generating an output image corresponding to the image generation instruction according to one or more layers corresponding to one or more layer identifiers contained in the image generation instruction, wherein the image generation instruction contains one or more layer identifiers of one or more layers selected by the user.
