Claim:
1. An endoscopic illumination system for illuminating a subject for stereoscopic image capture, the illumination system comprising: a light source which outputs multi-spectral light; first and second light paths configured to transmit the multi-spectral light; a first complementary multiband bandpass filter (CMBF) and a second CMBF, the first CMBF being situated in the first light path and the second CMBF being situated in the second light path, wherein the first CMBF and the second CMBF filter the multi-spectral light incident thereupon to output filtered light towards the subject for reflection as reflected light; and a camera which captures video images of the subject and generates corresponding video information and a synchronization signal, the video information including a plurality of left and right image frame information, the camera receiving the reflected light reflected from the subject and passing through a pupil CMBF pair and a detection lens, wherein the pupil CMBF includes a first pupil CMBF and a second pupil CMBF, the first pupil CMBF being identical to the first CMBF and the second pupil CMBF being identical to the second CMBF, and wherein the detection lens includes one unpartitioned section that covers both the first pupil CMBF and the second pupil CMBF.
