    • A device (10) is provided having a visual user interface enabling a user to select one of one or more displayed objects (O1, O2, O3, O4) with a cursor (CR) having a cursor area. The device comprises a cursor control facility (12) for controlling display of the cursor and a calculating facility (14) for calculating for each object that is at least partly within the cursor area a coverage fraction (ω oi ). The coverage fraction (ω oi ) is indicative for the fraction of that object (Oi) covered by the cursor and for summing these coverage fractions to obtain a coverage indicator (CI). The cursor control facility is arranged for adapting a size of the cursor to a size that achieves a predetermined value for the coverage indicator. Furthermore a method and a storage medium are provided.
    • 提供一种设备(10),其具有使用户能够用具有光标区域的光标(CR)选择一个或多个显示对象(O1,O2,O3,O4)中的一个的可视用户界面。 该设备包括用于控制光标显示的光标控制设备(12)和用于为至少部分地在光标区域内的每个对象计算覆盖率(omega)的计算设备(14)。 覆盖率(omegaoi)表示光标所覆盖的对象(Oi)的分数,并将这些覆盖分数相加以获得覆盖指标(CI)。 光标控制设备被布置成使光标的大小适应于达到覆盖指示符的预定值的大小。 此外,提供了一种方法和存储介质。

    • A three dimensional [3D] image signal is processed for rendering 3D image data (33) on a specific 3D display, e.g. an auto-stereoscopic display. A first depth map (34) and saliency of the 3D image data are determined. A display depth sub-range (35) of a usable depth range (36) of the 3D display is determined and provides a higher 3D image quality for a viewer than the 3D image quality across the usable depth range. A depth mapping function is determined in dependence of the saliency data. The depth mapping function maps the first depth map to a second depth map for generating views for the 3D display. Advantageously the salient range of depth values is mapped towards the display depth sub-range.

    • A method of adding a new device (221) to a device group (210), the device group (210, 220) including a plurality of devices, wherein each device in the device group possesses a device group key and device keys of all other devices in the device group for encryption of messages, except its own device key. The method includes: establishing a secure connection between the new device (221) and a first device (211) in the device group (210); sending, by the first device (211) in the device group (210), the device group key and device keys of all other devices (212, 213, …, 21N) in the device group (210) to the new device (221); distributing, by one of the other devices (212, 213, …, 21N) in the device group (210), the device key of the first device (211) in the device group (210) to the new device (221); generating and distributing, by one of the devices (211, 212, 213, …, 21N) in the device group (210), a device key of the new device (221) to all other devices (211, 212, 213, …, 21N) in the device group (210). This approach is also generalized to k -resilient schemes.
