The embodiment of the invention discloses an image generation method, device and equipment based on an LCD liquid crystal device and a storage medium, and the device comprises a focusing lens and the LCD liquid crystal device associated with the focusing lens, and the LCD liquid crystal device is arranged between the focusing lens and an image sensor, or the focusing lens is arranged between the LCD liquid crystal device and the image sensor. The method comprises the steps of: determining a current image display mode and a focusing mode, wherein the image display mode comprises a visible light mode and a near-infrared mode, and the focusing mode comprises automatic focusing, semi-automatic focusing and external control focusing; and controlling the power-on voltage or current of the LCD liquid crystal device according to the image display mode, so that the light passing through the LCD liquid crystal device and the focusing lens is sensed by the image sensor to generate an image. The image generation mode and mode switching provided by the scheme cannot be influenced by the work of the voice coil motor and the like to generate errors, on the other hand, a magnetic field cannot be generated to reversely influence the work of devices such as the voice coil motor and the like, and ultra-miniaturization can be realized.

Description

technical field [0001] The embodiments of the present application relate to the image field, and in particular to an image generation method, device, device and storage medium based on an LCD liquid crystal device. Background technique [0002] Autofocus and spectrum switching are currently one of the most widely used optical technologies. Usually, autofocus uses technologies such as voice coil motors and liquid lenses. The voice coil motor controls the position of the lens through a magnetic induction coil, while the liquid lens controls Control the curved surface of the lens to achieve the focusing function; the usual spectrum switching technology uses physical principles, using a motor to drive two physical lenses with different spectra, and by changing the position of the physical lenses with different spectra to achieve filtering of different spectra and spectrum switching Features. [0003] Since the autofocus and spectrum switching devices both use magnetic induction...

AI Technical Summary

Problems solved by technology

[0003] Since the autofocus and spectrum switching devices both use magnetic induction technology, if they are forcibly integrated, they will interfere with each other, and the related devices cannot be precisely controlled, and the design purpose cannot be achieved

On the other hand, the larger the lens, the greater the weight, which affects the accuracy and flexibility of the voice coil motor; while the smaller the lens, although the weight is lighter, the accuracy and flexibility of the voice coil motor are satisfied, but what follows is The back focal length is getting smaller and smaller, so that the distance between the lens and the image sensor is getting smaller and smaller, often less than 1mm, and it is impossible to place two physical lenses and transmission structures with different spectra that are driven mechanically

Ultra-thin devices such as mobile phones and monitors are changing with each passing day. In such a narrow space, it is impossible to mechanically push two physical lenses with different spectra. It is easy to scratch the lens lens or image sensor, and it is impossible to achieve ultra-thin and miniaturized equipment.

[0004] Intelligent machine vision technologies such as robots, intelligent driving, face recognition, and intelligent monitoring continue to develop and popularize. These technologies are all based on image imaging technology, so they are particularly dependent on cameras. Various lighting conditions will seriously affect the normal operation of the equipment, especially in various outdoor lighting environments, the current camera technology can no longer meet its actual needs
