Abstract:
An imaging device is disclosed. The device comprises an image sensor configured to capture image data and a filter. The filter is configured to selectively control a range of wavelengths of light entering the image sensor. The filter comprises a liquid crystal structure configured to pass the range of wavelengths in a first configuration and reflect the range of wavelengths in a second configuration. The device further comprises a controller in communication with the image sensor and the filter. The controller is configured to adjust the filter from the first configuration to the second configuration in response to an environmental lighting condition.
