Claim One:
1. A portable apparatus comprising: a display configured to show a visual controllable element; a camera unit configured to capture a plurality of consecutive images; memory including program code; a processor; and the memory and the program code being configured with the processor to cause the portable apparatus, in one of a plurality of operating situations, wherein one of the plurality of operating situation is defined based on a movement speed of the portable apparatus, to perform: dividing a first image of the plurality of consecutive images into a plurality of segments; selecting a fixed point from the first image; determining a location coordinate of the selected fixed point; dividing a second image of the plurality of consecutive images into a plurality of segments, the second image being the next image following the first image of the plurality of consecutive images; determining a location coordinate of the selected fixed point from the second image; calculating a movement vector of the selected fixed point between the determined location coordinate of the first image and the determined location coordinate of the second image; determining a three-dimensional change relative to at least the movement vector; and controlling the visual controllable element on the display based on the three-dimensional change; and adjusting an image frequency of the camera unit to at least the portable apparatus movement speed.
