1. An endoscopic camera system comprising:
an optical assembly;
a first color image sensor in optical communication with the optical assembly, the first image sensor receiving a first exposure of visible light and transmitting a first low dynamic range image;
a second color image sensor in optical communication with the optical assembly, the second image sensor receiving a second exposure of visible light and transmitting a second low dynamic range image, the second exposure being higher than the first exposure;
a monochrome image sensor in optical communication with the optical assembly, the monochrome image sensor receiving an exposure of non-visible light and transmitting a monochrome image;
an HDR processor coupled to the first color image sensor and the second color image sensor for receiving the first low dynamic range image and the second low dynamic range image, the HDR processor being configured to combine the first low dynamic range image and the second dynamic range image into a high dynamic range image; and
a combiner coupled to the HDR processor and the monochrome image sensor, the combiner being configured to combine the high dynamic range image with the monochrome image.
