1. A liquid crystal lens imaging apparatus, comprising: a lens group including at least a liquid crystal lens; a drive circuit connected to the liquid crystal lens to drive the liquid crystal lens into an out-of-focus state or into an in-focus state; an image collecting unit configured to collect light signal passing through the liquid crystal lens and to generate an image according to the light signal, wherein, 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 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; and an image processing unit 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.
