Camera device having a parabolic mirror set between dual cameras and method for shooting light having at least two wavelength bands

A method of shooting light having at least two wavelength bands, comprising:

• receiving incident light by a parabolic mirror arranged between a first lens and a second lens disposed facing each other;
• reflecting light having a second wavelength band by the parabolic mirror, light having a first wavelength band different from the second wavelength band penetrating through the parabolic mirror at the same time;
• receiving the light having the first wavelength band by a first camera containing the first lens able to receive the light having the first wavelength band;
• receiving the light having the' second wavelength band by a second camera including the second lens able to receive the light having the second wavelength band;
• and
• performing photoelectric conversion on the received light having the first wavelength band and the received light having the second wavelength band so as to form two images, respectively,
• wherein, the first camera is a non-fisheye camera;
• the first lens of the first camera is a non-fisheye lens;
• the second camera and the parabolic mirror form a catadioptric camera;
• and an aperture stop of the non-fisheye lens coincides with a focal point of the parabolic mirror.
