Abstract: A method of implementing location-guided visual code scanning from long distances starts with a processor receiving from client device a media content item and a location of the client device. Processor detects a portion of the media content item including image of captured visual code. Processor aligns image of captured visual code in the portion of the media content item to generate rectified image of captured visual code. Processor selects, based on location of the client device, subset of visual codes of the visual codes in database that stores visual codes and visual code location estimates associated with the plurality of visual codes. Processor detects matching visual code from the subset of visual codes using the rectified image of the captured visual code and causes a selectable item associated with the matching visual code to be displayed by the client device. Other embodiments are described herein.

Abstract: An apparatus that comprises a camera opening that couples to a camera lens of a camera and a viewfinder collocated with the camera opening. The viewfinder comprises a mirror coupled to an aperture having a width and a height. The mirror is recessed into the apparatus at a depth defined by a height of the aperture. The width and the height of the aperture being based on a field of view of the camera. The viewfinder having a field of view that approximates the field of view of the camera for a range of viewing angles. Other embodiments are described herein.
