Abstract: A controller circuit includes a background buffer, M safety information buffers, and an image mixer. The background buffer is used to store a background image. The M safety information buffers is used to store M images of M selected pieces of safety information, M being a positive integer. The image mixer is coupled to the M safety information buffers and the background buffer, and is used to generate an output image according to the background image and the M images of M selected pieces of safety information.
