1. A camera module, comprising an optical lens component, a light filtering layer comprising at least one light filtering unit, an image sensor and a drive module, wherein
the optical lens component is configured to receive a light beam from a photographed object, and transmit the light beam to the light filtering layer;
the drive module is configured to move the light filtering layer, along a plane parallel to the image sensor, between K regions, such that the light filtering unit is configured to transmit light signals at K different spatial positions that are obtained in the K regions to corresponding photosensitive units in the image sensor, wherein K is an integer greater than 1, and a movement distance between two adjacent regions is less than a distance between geometric centers of two corresponding adjacent photosensitive units;
the light filtering layer is configured to transmit light signals filtered at different positions to the image sensor; and
the image sensor is configured to receive the light signals filtered at the different positions that are transmitted from the light filtering layer, and determine image information based on the light signals filtered at the different positions.
