Abstract
A three-plate camera includes an IR prism that causes an IR image sensor to receive incident IR light of light from an observation part, a visible prism that causes a visible image sensor to receive incident visible light of light from the observation part, a specific prism that causes a specific image sensor to receive incident light of a specific wavelength band of light from the observation part, and a video signal processing unit that generates an IR video signal, a visible video signal, and a specific video signal of the observation part based on respective imaging outputs of the IR image sensor, the visible image sensor, and the specific image sensor, combines the IR video signal, the visible video signal, and the specific video signal, and outputs a combined video signal to a monitor.
