Method and device for compressing image, and electronic device

A device for compressing an image, disposed on an electronic device configured with a display screen, comprising:

• a processor, and
• a memory, configured to store a computer program comprising program instructions,
• wherein the processor is configured to:
• acquire a resolution of the display screen and a resolution of an image to be compressed;
• detect whether the resolution of the image to be compressed is greater than the resolution of the display screen;
• and
• compress the resolution of the image to be compressed to a target resolution according to the resolution of the display screen when the resolution of the image to be compressed is greater than the resolution of the display screen, a difference between the target resolution and the resolution of the display screen being within a preset resolution range.

An electronic device, comprising a housing, a processor, a memory, a display screen, a circuit board and a power supply circuit, wherein,

• the circuit board is disposed in a space enclosed by the housing;
• the processor and the memory are positioned on the circuit board;
• the display screen is externally embedded on the housing and connected with the circuit board;
• the power supply circuit is configured to provide power for respective circuits or components of the electronic device;
• the memory is configured to store executable program codes and data;
• and
• the processor is configured to run a program corresponding to the executable program codes by reading the executable program codes stored in the memory, to perform following operations:
• acquiring a resolution of the display screen and a resolution of an image to be compressed;
• detecting whether the resolution of the image to be compressed is greater than the resolution of the display screen;
• and
• when the resolution of the image to be compressed is greater than the resolution of the display screen, compressing the resolution of the image to be compressed to a target resolution according to the resolution of the display screen, a difference between the target resolution and the resolution of the display screen being within a preset resolution range.
