A vertical synchronization signal-based control method. The method includes the electronic device draws a first layer of a first application in response to a first vertical synchronization signal, and buffers the first layer to a first buffer queue. The electronic device performs, in response to a second vertical synchronization signal, layer composition on the layer buffered in the first buffer queue, to obtain an image frame. The electronic device adjusts a signal period of the first vertical synchronization signal to first duration if a quantity of layers buffered in the first buffer queue is less than a first preset threshold, where the first duration is less than a signal period of the second vertical synchronization signal.

Vertical synchronization signal-based control method and electronic device

A method includes: displaying an interaction interface of an application, and when a preset operation performed by a user on the interaction interface is detected, decoding to-be-displayed image data of the application into bitmap data, and encapsulating the bitmap data into texture data; storing the texture data in a memory partition accessible to a graphics processing unit GPU; triggering the GPU to read the texture data and perform drawing processing to obtain rendered data; and triggering a display to display an image based on the rendered data.

Image processing method and apparatus

Embodiments of this application provide a page drawing control method, apparatus, and device. The method includes: obtaining a drawing instruction for a first page, where the drawing instruction is used to instruct to draw the first page, the first page includes a first control, and the first control includes at least one child control; and if it is determined that an image corresponding to the first control exists and the first control and the child control in the first control are not updated, drawing the first control based on the image corresponding to the first control, or if it is determined that an image corresponding to the first control does not exist or the first control or the child control in the first control is updated, generating the image corresponding to the first control and drawing the first control. In this way, page drawing efficiency is improved.

Page drawing control method, apparatus, and device

A picture rendering method includes obtaining first picture data of a current frame; comparing the first picture data with currently recorded second picture data of a previous frame to determine a first part in the first picture data that does not change with respect to the second picture data and a second part in the first picture data that changes with respect to the second picture data; and rendering the second part in the current frame, including reusing a rendering result of the first part in the previous frame to obtain and display a rendering result of the current frame.
