Abstract

A shutter system may be used as part of an imaging device, such as a CMOS imaging device. The shutter system comprises a support structure, and first and second shutter members are rotatably mounted to the support structure so as to have respective first and second axes of rotation. The first and second shutter members have respective first and second shutter apertures defined therethrough, with the first shutter apertures having a first circular orbit about the first axis of rotation and the second shutter aperture having a second circular orbit about the second axis of rotation. The first and second shutter members at least partially overlap, and the first circular orbit and the second shutter circular orbit also at least partially overlap, so that rotation of the first and second shutter members at different frequencies cycles the first and second shutter apertures into and out of registration with each other.
