1. An image processing method, wherein the method is applied to a computer system comprising a host operating system, wherein a kernel mode graphics driver and a first guest operating system are installed in the host operating system, a user mode graphics driver is deployed in the first guest operating system, the first guest operating system further comprises an image compositor directly connected to an image capture program, and the method comprises:
generating, by the user mode kernel driver based on a first application programming interface (API) call request, a first instruction that can be identified by a graphics processing unit;
sending the first instruction to the kernel mode graphics driver, wherein the first API call request is used to request to perform an image rendering operation; and
controlling, by the kernel mode graphics driver based on the first instruction, the graphics processing unit to perform image rendering.
