Abstract: An apparatus including an image sensor; a lens for focusing an optical image onto the image sensor; a driver configured to move the lens at least in a first direction, wherein the lens includes a central region and first and second outer regions on either side of the central region in the first direction, wherein the first and second outer regions optically distort more than the central region.

Abstract: The method relates to minimizing power consumption in a computing device, which executes the requested tasks in a high power mode, in which it has normal processing power and, correspondingly, normal power consumption, and which, after it has executed the requested tasks, is switched to a low power mode, in which it has limited processing power and, correspondingly, a considerably lower power consumption. In the method of the invention, the power consumption of a computing device is decreased by lengthening the time during which the device remains in the low power mode in such a way that the device is not switched to a high power mode immediately when the user starts the input, but the switching is delayed.
