Important information with respect to image generation such as computer game video generation can be lost once the full image is composed. To avoid this, a customized capture script is created for a computer game to specify what to capture, for future use, in the middle of rendering a game video frame, such as frame buffer, depth buffer, stencil buffers, etc. The script also specifies when during frame rendering the data is to be recorded. By capturing data mid-frame, object boundaries on the screen and relative distances between objects can be inferred. This information can be used in 2D-to-3D conversion, object coloring for increased contrast, object highlighting, etc.
