Abstract
Embodiments of the present application disclose various super-resolution image acquisition methods and acquisition apparatuses, wherein a super-resolution image acquisition method comprises: determining sub-pixel level target offset distances of corresponding logic pixel points in respective to-be-adjusted regions of image sensors of any two adjacent cameras of a camera array, the respective to-be-adjusted regions being imaging regions of the image sensors respectively corresponding to a first region, and the first region being at least a local part of a scene; adjusting pixel point distribution of image sensors of respective cameras in the camera array according to the sub-pixel level target offset distances; acquiring images of the scene respectively based on the cameras after adjustment; and acquiring a super-resolution image of the scene according to the acquired images. The embodiments of the present application improve imaging quality of a sub-image in the super-resolution image corresponding to the first region.
