1. A liquid crystal lens imaging apparatus, comprising: a lens group including at least one liquid crystal lens; a drive circuit connected to the at least one liquid crystal lens to drive the at least one liquid crystal lens into an out-of-focus state or into an in-focus state; an image sensor configured to collect light signal passing through the at least one liquid crystal lens and to generate an image according to the light signal, wherein, when the at least one liquid crystal lens is in the in-focus state, the image sensor generates an in-focus image of the light signal and, when the at least one liquid crystal lens is in the out-of-focus state, the image sensor generates at least one out-of-focus image of the light signal as a reference image; and an image processor connected to the image sensor 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, based on: 
 I f −I r =I f x *(δ− h )+ n wherein, I f x represents the final image, I f represents the in-focus image, I r represents the reference image, * represents the convolution operator, δ represents an impulse response, h represents a blurring function and n represents a system noise of the at least one liquid crystal lens imaging apparatus.
