Image shooting device and shooting method thereof

Abstract

The invention discloses an image shooting device and a shooting method thereof. The image shooting device comprises a liquid crystal lens array, an image sensor and a driving module, wherein the liquid crystal lens array is composed of multiple liquid crystal sub-lenses; a preset distance exists between the liquid crystal lens array and the image sensor; the driving module is electrically connected with the liquid crystal lens array; and the driving module is used for regulating a focal distance of each of the liquid crystal sub-lenses according to the distance between an object of an image obtained by a camera lens of the image shooting device and corresponding each of the liquid crystal sub-lenses when obtaining the image, so that light rays of each object, after passing through the corresponding each of the liquid crystal sub-lenses, are focused on a plane where the image sensor locates. Because the driving module can regulate the focal distance of each of the liquid crystal sub-lenses, different parts of the liquid crystal lens array have different focal distances, and to-be-shot objects at different distances can be focused clearly, thereby obtaining an all-in-focus image. Compared with the existing all-in-focus shooting device, the structure is simple, the response speed is fast, no post-processing is needed and the operation is simple.

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to an imaging device and a shooting method thereof. Background technique [0002] Modern people like to record life in the form of taking photos, and photography is getting more and more attention as a profession or as a hobby. People often encounter the following two problems when taking pictures with a camera: [0003] One situation is that in order to highlight feature points or create special effects when taking pictures, the target object will be focused and displayed clearly, while the surrounding background will be blurred. Another situation is that when shooting landscapes, flowers, buildings and other subjects, it is often desired to show all the pixels of the entire picture, that is, to obtain a full depth photo, which requires that every point in the lens be accurately focused. Once the ordinary camera is finished taking pictures, the focus cannot be changed during pos...

AI Technical Summary

Problems solved by technology

The micro-lens array of the light-field camera is made up of traditional micro-lenses. Traditional lenses cannot achieve fast and flexible zooming. Therefore, light-field cameras must rely on complex physical and mathematical knowledge to obtain images with different focal points. These complex technologies are not conducive to Market Popularization of Light Field Cameras

Using manual shooting combined with image processing software to synthesize panoramic depth photos, the process is more complicated and requires higher photography skills of the photographer. The photographer needs to manually control the uniform exposure, ensure the best aperture, and even use a tripod to ensure the camera. the stability of
