Claim 14:
15. A computer system, wherein the computer system comprises a first processor, a memory, and a graphics processing unit, wherein
the memory is configured to store computer-readable instructions;
the first processor is configured to run the computer-readable instructions, to implement an image processing method applied to the computer system, the computer system further comprises a host operating system, a kernel mode graphics driver and a first guest operating system installed in the host operating system, a user mode graphics driver 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, wherein the graphics processing unit is configured to perform image rendering under control of the first processor.
