Abstract
The present invention provides a liquid crystal lens imaging apparatus and method. Wherein, the imaging apparatus comprises a lens group including at least a liquid crystal lens, a drive circuit, an image collecting unit and an image processing unit. The drive circuit is connected to the liquid crystal lens to drive the liquid crystal lens respectively into an in-focus state or into an out-of-focus state. The image collecting unit is configured to collect light signal passing through the liquid crystal lens to generate an image. When the liquid crystal lens is in the in-focus state, the image collecting unit generates an in-focus image of the light signal and, when the liquid crystal lens is in the out-of-focus state, the image collecting unit generates an out-of-focus image of the light signal as a reference image. Further, the image processing unit is connected to the image collecting unit to receive both the in-focus image and the reference image, to process the in-focus image using the reference image to generate a processed image, and to deconvolute the processed image to generate a final image.
