Abstract: The present disclosure provides a method for determining a depth value. The method includes adjusting a distance between an image sensor and a lens included in an image acquisition device M times by moving the image sensor, where M is an integer greater than 1; acquiring an image for each N of M times after adjusting the distance between the image sensor and the lens, where N is an integer less than or equal to M; calculating depth values of pixel points in the N acquired images; and determining a target depth value of the pixel point at a position in each of the images based on the depth value of the pixel point in each image.
