Abstract
Liquid crystal lens imaging apparatus and method are provided. The apparatus includes: juxtaposed at least two lens groups, a rubbing direction of alignment layer of a LC lens in one lens group being perpendicular to a rubbing direction of alignment layer of a LC lens in neighboring another lens group; an image capture unit for forming first and second image signals according to light signals passing through the lens groups at a first moment and forming third and fourth image signals according to light signals passing through the lens groups at a second moment; an image processor for processing the image signals to obtain a final formed image signal; and a driving circuit for controlling the LC lenses to be non-lens state and lens state respectively at the first and second moments. No polarizer is used, the intensity of received incident light is increased and the thickness is reduced.
