Claim 13:
14. The computer system according to claim 9, wherein the image compositor being configured to:
when the image capture program is in the enabled state, perform the image composition operation on the plurality of layers obtained by the graphics processing unit through rendering comprises:
the image compositor is configured to:
when the image capture program is in the enabled state, read the plurality of layers obtained by the graphics processing unit through rendering;
the image compositor is configured to send an image composition instruction to the user mode graphics driver by using a generic buffer manager, wherein the image composition instruction is used to request to perform the image composition operation on the plurality of layers;
the user mode graphics driver is configured to:
generate, based on the image composition instruction, a second instruction that can be identified by the graphics processing unit, and
send the second instruction to the kernel mode graphics driver; and
the kernel mode graphics driver is configured to control, based on the second instruction, the graphics processing unit to perform the image composition operation on the plurality of layers.
