1. An image collection system, comprising: a gaze point detection device configured to detect the location of a gaze point of a user with respect to the user; and at least one image collection device configured to focus and collect at least one first image according to the location of the gaze point with respect to the user; wherein the gaze point detection device comprises: a fundus image collection module configured to collect at least one second image of a fundus of the user; at least one adjustable lens module configured to adjust at least one imaging parameter of an optical path between the fundus image collection module and an eye of the user until the fundus image collection module obtains at least a subset of the at least one second image that satisfies at least one defined clarity criterion; and an image processing module configured to process at least the subset of the at least one second image that satisfies the at least one defined clarity criterion, obtain the at least one imaging parameter corresponding to at least the subset of the at least one second image that satisfies the at least one defined clarity criterion and an optical axis direction of the eye, and determine the location of the gaze point of the user with respect to the user.
