Abstract
An electronic camera system is operable in a first operating state, in which a video signal delivered by the image sensor is based on the detection of visible light only, and a second operating state, in which a video signal delivered by the image sensor is at least in part based on the detection of infrared light. The camera system includes an electronic image sensor that is sensitive to visible light and infrared light, a lens system that is transparent to visible light and infrared light and serves for projecting an image onto the image sensor and a filter assembly arranged in front of the image sensor.
Claims16
An electronic camera comprising:
- an image sensor that is sensitive to visible light and infrared light, the image sensor having a plurality of pixels;
- a lens system that is transparent to visible light and infrared light and serves for projecting an image onto the image sensor;
- and
- a filter assembly arranged in front of the image sensor and having a plurality of filter elements including a first filtering element that is transparent to infrared light and a second filtering element that is impervious to infrared light, wherein one element of the plurality of filtering elements transmits light to just one of the plurality of pixels;
- wherein the electronic camera is operable in a first operating state, in which an image signal generated by the image sensor is based on the detection of visible light only, and a second operating state, in which the image signal generated by the image sensor is at least in part based on the detection of infrared light.
