The invention discloses a multi-spectrum filter switching device for an image imaging device. The device is arranged between an optical lens and the image imaging device. The device comprises a base; a circuit board is arranged on the base; a light sensitive window is arranged on the base; the base is provided with one or more than one rotating disc; each rotating disc is transmitted independently via a transmission mechanism; the rotating disc is arranged on the base via a rotating shaft and can rotate forwardly and backwardly around the rotating shaft; each rotating disc is provided with three or more than three light transmitting holes; a different filter is arranged on each light transmitting hole; and when the rotating disc rotates, the light transmitting hole can be aligned with the light sensitive window. According to the switching device, the structure is simple, multiple different spectrums can be formed through rotation and combination of filters on one or more than one rotating disc, and different requirements in different conditions can be met.
