Abstract
An image processing method based on a vertical synchronization signal and an electronic device, related to the field of image processing and display technologies. The method includes that the electronic device draws one or more layers in response to a first vertical synchronization signal; and the electronic device renders, in response to a second vertical synchronization signal, the layers drawn by the electronic device.
Claims16
An image processing method, comprising:
- drawing, by an electronic device and during a first synchronization period spanning a moment ta to a moment tb, one or more layers in response to a first vertical synchronization signal triggered at the moment ta;
- after completion of the drawing, triggering, by the electronic device, a second vertical synchronization signal at the moment tb or after the moment tb that is a different vertical synchronization signal than the first vertical synchronization signal;
- and
- in response to the triggering of the second vertical synchronization signal at the moment tb or after the moment tb, rendering, by the electronic device and during a second synchronization period spanning the moment tb to a moment tc, the one or more layers.
1 more element
An image processing method, comprising:
- drawing, by an electronic device, one or more layers in response to a first vertical synchronization signal;
- rendering the one or more layers;
- obtaining an image frame, wherein obtaining the image frame comprises:
- in response to a determination, by the electronic device, that the electronic device has not completed the rendering of the one or more layers within a preset single-frame duration, performing, by the electronic device, layer composition on the one or more layers in response to a first second vertical synchronization signal after the rendering of the one or more layers is completed to obtain the image frame;
- or
- in response to a determination, by the electronic device, that the electronic device has completed the rendering of the one or more layers within a preset single-frame duration, saving, by the electronic device, the one or more layers to a buffer, and performing, by the electronic device, layer composition on the one or more layers stored in the buffer in response to a second second vertical synchronization signal after the rendering of the one or more layers is completed to obtain the image frame;
- and,
- displaying, by the electronic device, the obtained image frame.
5 more elements
An electronic device, comprising:
- at least one processor;
- and
- a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
- drawing, during a first synchronization period spanning a moment ta to a moment tb, one or more layers in response to a first vertical synchronization signal triggered at moment ta;
- after completion of the drawing, triggering a second vertical synchronization signal at the moment tb or after the moment tb that is a different vertical synchronization signal than the first vertical synchronization signal;
- and
- in response to the triggering of the second vertical synchronization signal at the moment tb or after the moment tb, rendering, during a second synchronization period spanning the moment tb to a moment tc, the one or more layers in response to the second vertical synchronization signal.
