Disclosed in the embodiments of the present invention are an image generation method, apparatus and device based on an LCD apparatus, and a storage medium. A focusing lens and an LCD apparatus associated with the focusing lens are comprised, wherein the LCD apparatus is arranged between the focusing lens and an image sensor, or the focusing lens is arranged between the LCD apparatus and the image sensor. The method comprises: determining the current image display mode and the current 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 according to the image display mode, controlling a power-on voltage or current of an LCD apparatus, such that the light passing through the LCD apparatus and a focusing lens is sensed by an image sensor, so as to generate an image. The image generation method and mode switching provided in the present solution are not affected by the work of a voice coil motor, etc., to generate an error; in addition, no magnetic field is generated to affect the work of means such as the voice coil motor, and ultra-miniaturization can be realized.
