Camera device having a parabolic mirror set between dual cameras and method for shooting light having at least two wavelength bands
Camera device and method for shooting light having at least two wavelength bands are disclosed. The camera device includes a first camera containing a first lens for receiving light having a first wavelength band; a second camera including a second lens for receiving light having a second wavelength band which is different from the first wavelength band, the second lens being disposed facing the first lens of the first camera; and a parabolic mirror set between the first camera and the second camera, able to let the light having the first wavelength band penetrate therethrough, and at the same time, reflect the light having the second wavelength band. The first camera is a non-fisheye camera. The first lens is a non-fisheye lens. The second camera and the parabolic mirror form a catadioptric camera. The aperture stop of the non-fisheye lens coincides with the focal point of the parabolic mirror.
