VEHICLE MOUNTED VIRTUAL VISOR SYSTEM WITH GRADIENT BLOCKING MODES

A virtual visor system is disclosed that includes a visor having a plurality of independently operable pixels that are selectively operated with a variable opacity. A camera captures images of the face of a driver or other passenger and, based on the captured images, a controller operates the visor to automatically and selectively darken a limited portion thereof to block the sun or other illumination source from striking the eyes of the driver, while leaving the remainder of the visor transparent. The virtual visor system advantageously adopts a gradient blocking mode for the optical state of the visor that includes a blocker and a transition gradient, which has the effect of making updates to optical state of the visor less distracting. Additionally, the transition gradient in the optical state of the visor makes the virtual visor system more robust against errors in positioning the blocker on the visor.
