ELECTRONIC DEVICE AND A METHOD FOR CONTROLLING THE FUNCTIONS OF THE ELECTRONIC DEVICE AS WELL AS PROGRAM PRODUCT FOR IMPLEMENTING THE METHOD
First Claim
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.

Abstract
The invention relates to an electronic device, which includes a display component, in which at least one controllable element is arranged to be visualized in its entirety, the control of which element is arranged to be based on determining a change (M) relating to the attitude or position of the device and camera means arranged to form image frames (IMAGE1, IMAGE2), and in which, in order to control the functions of the device, such as, for example, to control the element, the change is arranged to be determined, using optical data-flow algorithms, from the image frames formed by the camera means, which image frames are arranged to be compared to each other in a set manner, and on the basis of which comparison the said change is arranged to be determined. The image frames are arranged to be segmented in a selected manner, from which at least one movement vector (SR, SL, SUp, SDown) determining the said change is arranged to be determined from at least some of the segments (SEGMENT1, SEGMENT2).
