A real-time multiband camera is provided to obtain different images in two among the infrared ray band, visible ray band, and ultraviolet ray band of an image photographed by photographing once, thereby removing a time difference between images of each band. A real-time multiband camera(1) comprises a lens portion(30), a dichroic mirror(40), a first imaging portion(10,11), and a second imaging portion(20,21). The lens portion receives a light wave. The dichroic mirror transmits or reflects the light wave flowed through the lens portion according to a wavelength. The first imaging portion converts a light wave transmitted by the dichroic mirror into an electric signal. The second imaging portion converts a light wave reflected by the dichroic mirror into an electric signal. The first imaging portion includes a first imaging device(10) for converting the light wave transmitted by the dichroic mirror into the electric signal. The second imaging portion includes a second imaging device(20) for converting the light wave reflected by the dichroic mirror in a direction crossing the light wave transmitted by the dichroic mirror into the electric signal. The lens portion is positioned between the lens portion and the dichroic mirror and includes an additional focus compensating lens(31) for compensating a focus according to at least one of intervals among the lens portion, the first imaging portion, and the second imaging portion, and the size of the first imaging portion and the second imaging portion.
