Patent ID: 6864473

Claim:
A method for adjusting the opacity of a matrix comprising a plurality of cells, the method comprising: receiving incident light intended for a receptor; receiving the incident light into a beamsplitter; refracting part of the incident light to a sensor; identifying a portion of the incident light that exceeds a predetermined threshold intensity; identifying a bright light source in the incident light; identifying a direction of the bright light source; identifying a direction of sight of the receptor; determining an angle from the direction of the bright light source and the direction of sight of the receptor; defining an active zone equivalent to a first predetermined range of angles associated with the direction of the bright light source and the direction of sight of the receptor; defining a passive zone equivalent to a second predetermined range of angles associated with the direction of the bright light source and the direction of sight of the receptor; determining whether the angle falls within the active zone or the passive zone; and adjusting the opacity of at least one cell of the matrix based on the identified portion, the identified bright light source, and the determination as to whether the angle falls within the active zone or the passive zone.
