Abstract
The present invention provides a liquid crystal lens image forming device and an image forming method. The image forming device includes: at least one liquid crystal lens; a drive circuit, which is connected to the liquid crystal lens to set, at a first moment, the liquid crystal lens in a non-lens state and to set, at a second moment, the liquid crystal lens in a lens state; at least one image pick-up unit generating a first image signal and a second image signal; and an image processing unit, which processes the first image signal and the second image signal to form a target image signal. The liquid crystal lens image forming device and image forming method do not involve the use of a polarization device, allows a single liquid crystal lens to clearly form an image, and reduces the thickness of the entire image forming device.
