Abstract
A mobile communication device includes a processor operably coupled to a memory and to a wireless communication subsystem operable to send and receive data, a camera operably coupled to the processor, a sensor operably connected to provide to the processor a distance between the camera and an element viewable by the camera. Instructions are stored in the memory; when these instructions are executed by the processor, the mobile communication device takes an image with the camera, uses the sensor to determine a distance between the camera and at least one object recorded in the image, receives a request for a desired measurement comprising one of a desired length measurement and a desired area measurement of an element in the image, calculates the desired measurement, and provides the desired measurement to the user.
