METHODS AND SYSTEMS FOR DEALING WITH PERSPECTIVE DISTORTION IN CONNECTION WITH SMARTPHONE CAMERAS

摘要

Arrangements are detailed to aid a user in positioning a camera-equipped device (e.g., a smartphone) at a particular viewing position relative to an object being imaged. Other embodiments discern the device's viewing position, and then undertake image or other processing that is dependent on such viewpoint. A great number of other features and arrangements are also detailed.
