<p>The invention relates to a method and a device for automatic zooming. The device comprises means (116) for forming difference data representing the difference in magnitude between each luminance pixel of a previous image and a corresponding luminance pixel of the present image; means (118, 124) for adding the formed difference data to a cumulative motion register, in which a data element corresponds to each luminance pixel of the image; means (136) for detecting as motion the data elements, whose value exceeds a pre-determined threshold value; and means (132) for zooming to the detected motion.</p> |
