A key recognition method and apparatus for use on a smartphone or similar. The viewfinder display for the phone's image sensor is provided with a registration mark or icon adapted to help align and register the image of a flat key being viewed through the image sensor. An image-recognition process running on the phone is used to capture and convert the key's image to an image file stored on the phone, and the user is prompted to enter identifying information for association with the image file. When an unknown key is found, it can be viewed through the image sensor, displayed on the viewfinder screen, registered in the registration icon, and compared by the image-recognition process to previously-stored key images to try and find a match. |
