Imaging device, control method for imaging device, electronic apparatus and non-transitory readable medium comprising first and second voltage signals applied to a liquid crystal lens assembly to adjust the focal position of a first and second linearly polarized light

A control method for an imaging device, wherein the imaging device comprises:

• an image sensor assembly, comprising a plurality of image sensor components distributed in an array;
• an liquid crystal lens assembly, located on a light incident side of the image sensor assembly, and provided with light control components corresponding to the image sensor components;
• wherein each of the light control components comprises:
• a first liquid crystal component and a second liquid crystal component which are disposed oppositely with each other, and the orientation of the liquid crystal molecules in the first liquid crystal component and the orientation of the liquid crystal molecules in the second liquid crystal component are perpendicular to each other;
• and a processing assembly, electrically connected with both the image sensor assembly and the liquid crystal lens assembly;
• wherein the control method comprises:
• obtaining, by the processing assembly, an amount of light received by image sensor components;
• and
• adjusting, by the processing assembly, a voltage applied to the light control components according to the amount of light so that the light control components adjust a focal position of emitted light to change a distance between the focal position and the image sensor components;
• the adjusting, by the processing assembly, the voltage applied to the light control components according to the amount of light so that the light control components adjust the focal position of the emitted light further comprises:
• determining, by the processing assembly, whether the total amount of light received within a threshold time period is less than a threshold value;
• generating, by the processing assembly, a first voltage signal and a second voltage signal in the condition that it is determined that the total amount of light received is less than the threshold value;
• and
• applying, by the processing assembly, the first voltage signal to the first liquid crystal components to adjust the focal position of a first light to the photosensitive parts, and applying, by the processing assembly, the second voltage signal to the second liquid crystal components to adjust the focal position of a second light to the photosensitive parts, wherein the first light and the second light are two linearly polarized lights which are converted from external ambient light passing through the liquid crystal molecules and the polarization direction of the first light and polarization direction of the second light are perpendicular to each other.
