1. A computer system, comprising:
a display panel;
an infrared camera and a visible camera both disposed under the display panel; and
a processing system, comprising:
a display driver circuit;
a system processor; and
a vision chip that independently from the system processor:
processes image data captured by the visible camera or the infrared camera through the display panel,
updates a state of the computer system based on the image data, and
instructs the display driver circuit to drive the display panel to display a system state indicator, wherein
updating the state of the computer system comprises, when the computer system is in a low power state:
selecting and displaying a first system state indicator including a first indicator for a human presence detection (HPD) mode and a second indicator for an inactive camera state, wherein
the first indicator is displayed around the visible camera in an first area of the display panel that overlaps the visible camera that provided the image data, and
the second indicator is displayed around the infrared camera in a second area of the display panel that overlaps the infrared camera, the infrared camera being disabled in the lower power state;
executing the HPD mode based on the image data;
in response to successfully performing a user identification by the HPD mode, causing the computer system to transition from the low power state to a power on state; and
in response to unsuccessfully performing the user identification by the HPD mode, selecting and displaying a second system state indicator including a third indicator for failed user identification and the second indicator for the inactive camera state, wherein
the third indicator is displayed around the visible camera in the first area while the computer system remains in the low power state, and
the second indicator is displayed around the infrared camera in the second area while the computer system remains in the low power state.
