A control device, for example a computer mouse, has image-recording means which are adapted to be moved, preferably manually, for controlling an object, for example a cursor on a computer screen, as a function of the movement of the image-recording means. The control device is adapted to record a plurality of images with partially overlapping contents when the image-recording means are being moved, the partially overlapping contents of the images enabling image-processing means to generate control signals indicating how the image-recording means have been moved. A method of controlling and a control device based on the turning of the image-recording means are also shown. |
