Disclosed are an image processing method and an electronic device, which relate to the field of image processing technologies. An electronic device draws a first layer, renders the first layer, and buffers the rendered first layer in a buffer queue. The electronic device finishes drawing the first layer before a first time, and the electronic device draws a second layer, renders the second layer, and buffers the rendered second layer in the buffer queue before the first time, where the first time is a time of arrival of a first vertical synchronization signal for triggering the electronic device to draw the second layer.

Image processing method and electronic device

Embodiments of this application provide a callback stream processing method and a device, and relate to the field of electronic technologies. In a callback stream scenario, an electronic device may set a preview stream and a callback stream in parallel. After an application sets a callback function, the electronic device may directly return, by using the callback function, callback stream data to the application for processing. This can shorten a time consumed for creating a preview stream and a callback stream, shorten a time consumed for obtaining callback stream data, and shorten a user waiting time.
