A mobile terminal for use in a cellular telecommunications network, the terminal comprising a video camera for receiving video images and indication means, the terminal being adapted to i) providing a first image for reference; ii) providing a second image for determining whether the image is aligned; ii) processing said first and second image, whereby the processing includes performing edge detection; iv) correlating the processed first and second image; and v) determine whether the image is misaligned. If mis-alignment is present, an indication of such can be made to the user in graphical, audio or tactical form along with an indication of how the mis-alignment may be corrected. A second embodiment independently claimed identifies mis-alignment by dividing the edge detected images into sub-images and identifying the strongest edge in each sub-image. |
