Patent ID: 8081230

Claim:
An image capturing device comprising: a memory storing a guiding system configured for guiding a user to capture an image comprising himself; a communication unit; and a processor configured for activating the guiding system to: perform a facial recognition function on a current checking image to determine a face portion in the checking image; determine if the face portion is fully within a predetermined region of the checking image; and control communication unit to instruct the user to adjust position of the image capturing device according to the position of the face portion in relation to the predetermined region upon the condition that the face portion is not fully within the predetermined region; wherein the predetermined region is determined by a first group of boundary coordinates in a predetermined coordinate system, the face portion being determined by a second group of boundary coordinates in the predetermined coordinate system according to face contours recognized in the image; the processor is capable of determining the position of the face portion in relation to the predetermined region by comparing the second group of boundary coordinates with the first group of boundary coordinates.
