Non-polarizing LCD shutter |
摘要 |
An electronic shutter apparatus and light shuttering method for a still image capturing device are provided according to the invention. In one embodiment, the apparatus includes a beam splitter positioned in an incoming light beam path and splitting the incoming light beam into a first light beam and a second light beam. The apparatus further includes first and second polarizing shutters respectively positioned in paths of the first and second light beams and capable of being electrically activated to transmit light and to respectively form first and second polarized light beams. A polarization orientation of light from the second polarizing shutter is in non-alignment with a polarization orientation of light from the first polarizing shutter. The apparatus further includes a beam combiner receiving and combining the first and second polarized light beams to form a substantially non-polarized resultant light beam. The resultant light beam is focused onto an image sensor.
