Abstract
A modulation control method for a filter device for avoiding flicker appearing in streamed video images before acquiring images, includes setting the exposure time to be equal or longer than an oscillating light source's period duration or to be as long as possible between two frames in the image acquisition of streamed video images, polarizing of incoming light in a first polarizer to turn into polarized light with a first polarization, altering the polarization of the light with the first polarization in an electro- or magneto-optic modulator by an angle α to turn into light with a second polarization, and reducing an amount of light with the second polarization in a second polarizer.
