Patent ID: 7991157

Claim:
A method involving a mobile telephony device, wherein the device comprises a processor, a display, and an optical system comprising a 2D image sensor and a lens, and wherein the optical system generates image data, the method comprising: capturing image data, using the optical system, corresponding to a field of view that encompasses at least part of an object bearing machine-readable encoding; detecting the machine-readable encoding; at least partially characterizing an affine distortion of the object as represented in the captured image data; generating a warped graphic feature that is distinct from the captured image data, yet is similarly affine-distorted; and as a consequence of the detected machine-readable encoding, presenting the warped graphic feature on the display of the mobile telephony device in conjunction with at least some of the image data by aligning the warped graphic feature relative to the object based upon the characteristics of the affine distortion of the object, wherein the warped graphic feature is presented in spatial registration with the object on the display, and wherein the warped graphic feature becomes a superimposed characteristic marking indicating that the detected machine readable encoding is present.
