摘要： 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.

摘要： A microlens array imaging device includes a main lens, a microlens array containing a plurality of microlenses, and an image acquisition unit. The main lens projects a first image of an object for the plurality of microlenses, each of which projects a second image of the first image on the image acquisition unit. Each second image includes an image circle and a circle of confusion around the image circle. A distance between an image circle of one microlens and an image circle of an adjacent microlens is equal to or greater than a summation of a radius of the second image corresponding to the one microlens and a radius of the image circle of the adjacent microlens, and is equal to or less than a summation of the radius of the second image corresponding to the one microlens and a radius of the second image corresponding to the adjacent microlens.

摘要： 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.

摘要： A liquid crystal lens imaging apparatus includes a lens group containing 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 into an out-of-focus state or into an in-focus state. The image collecting unit is configured to collect light signal passing through the liquid crystal lens and to generate an image according to the light signal. 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. Further, the image processing unit is connected to the image collecting unit to receive both the in-focus image and the out-of-focus image and to process the in-focus image using the out-of-focus image to obtain a processed in-focus image as a final generated image.
