Method and apparatus for setting background picture of unlocking interface of application, and electronic device

An apparatus for setting a background picture of an unlocking interface of an application, wherein the apparatus comprises a non-transitory computer-readable medium comprising computer-executable instructions stored thereon, and an instruction execution system which is configured by the computer-executable instructions to implement at least one of:

• an icon acquiring module, configured to acquire a first icon file of an application to be unlocked;
• a size processing module, configured to perform a scaling processing on the first icon file of the application to be unlocked acquired by the icon acquiring module, so as to acquire a second icon file with a preset image size;
• a special effect processing module, configured to perform a special effect processing on the second icon file acquired by the size processing module, so as to acquire a special effect picture, and to store the special effect picture in a preset storing location;
• and
• an unlocking background displaying module, configured to call, when an instruction for generating the unlocking interface of the application to be unlocked is detected, a special effect picture relevant to the application to be unlocked currently, to scale-up the special effect picture relevant to the application to be unlocked currently to acquire a first scaled-up special effect picture and to display partial content of the first scaled-up special effect picture as the background picture of the unlocking interface.

An electronic device, comprising a housing, a processor, a memory, a display, a circuit board and a power supply circuit, wherein the circuit board is disposed in an inner space enclosed by the housing, the processor and the memory are both mounted on the circuit board;

• the power supply circuit supplies power to the circuits or components of the electronic device;
• the memory stores executable program code;
• and the processor executes a program corresponding to the executable program code by reading the executable program code stored in the memory, so as to perform following steps:
• acquiring a first icon file of an application to be unlocked;
• performing a scaling processing on the first icon file of the application to be unlocked, so as to acquire a second icon file with a preset image size;
• performing a special effect processing on the second icon file, so as to acquire a special effect picture, and storing the special effect picture in a preset storing location;
• and
• calling, when an instruction for generating the unlocking interface of the application to be unlocked is detected, a special effect picture relevant to the application to be unlocked currently, scaling-up the special effect picture relevant to the application to be unlocked currently to acquire a first scaled-up special effect picture and displaying partial content of the first scaled-up special effect picture as the background picture of the unlocking interface.
