Patent ID: 7561741

Claim:
A mobile communication terminal comprising: a photographic apparatus connected to the terminal; an image processing unit for processing images produced by the photographic apparatus, wherein control information is developed responsive to movement occurring in the images; and an operational controlling unit for corresponding an operational function of the terminal to the control information, wherein a first image is produced from an object having a first categorical feature and a second categorical feature, and a second image is produced from the object, such that a first value is attributed to a first midpoint of the first categorical feature and a second value is attributed to the second categorical feature, wherein the image processing unit processes the images by: extracting the first value from at least one of the processed images; comparing the first value to an initialization value; determining a first difference between the first value and the initialization value; developing first control information derived from the first difference; and generating a control information signal based on the first control information.
