Abstract
An adaptive filter system and a method for controlling the adaptive filter system are described herein. The system can includes one or more filters to attenuate incoming light. The one or more filters can be moved by one or more actuators. The method can capture image data from an imaging device through the one or more filters. Information can be determined from the captured image data. The one or more filters can be moved to a position for capturing image data based on the information.
Claims12
An adaptive filter system, comprising:
- a graduated neutral density filter adapted to attenuate incoming light captured by an imaging device, the graduated neutral density filter having different optical densities at different positions;
- at least one actuator coupled to the graduated neutral density filter and adapted to move the graduated neutral density filter among positions for attenuating the incoming light captured by the imaging device;
- a controller configured to:
- detect any two selected from a group consisting of:
- an angle of incidence,
- a hue, and
- a saturation of an image captured by an imaging device;
- and
- adjust a position of the graduated neutral density filter based on the any two selected from the group consisting of the angle of incidence, the hue, and the saturation of the image;
- and
- a cleaning apparatus configured to apply any of a chemical solution, compressed gas, an electric field, or a magnetic field to the graduated neutral density filter to remove debris from the graduated neutral density filter.
A method comprising:
- capturing, by an imaging device, image data through a graduated neutral density filter having different optical densities;
- controlling at least one actuator to move the graduated neutral density filter to particular positions to attenuate incoming light captured by the imaging device;
- applying a forward current to a rotor to cause a stator, associated with an arm, to pivot or rotate 90 degrees counterclockwise to cover an aperture of the imaging device or a reverse current to the rotor to cause the stator to pivot or rotate 90 degrees clockwise to return to a housing;
- and
- cleaning the graduated neutral density filter via any of a chemical solution, compressed gas, an electric field, or a magnetic field.
