Abstract: Systems, apparatuses, and methods for using a half-shield phase detection auto-focus (PDAF) sensor for auto-exposure convergence are disclosed. A camera includes at least one or more half-shield PDAF sensors and control logic for performing an automatic exposure control convergence procedure. The control logic receives half-pixel values from half-shield PDAF sensors for a first frame. The control logic calculates twice the value of each half-pixel value captured by the half-shield PDAF sensors for the first frame. Then, the control logic adjusts an exposure setting used for capturing a second frame based on how much twice the value of each sensor value is over the maximum pixel intensity value. This approach allows the automatic exposure control convergence procedure to converge more quickly than prior art procedures.

Abstract: An apparatus and methods for efficiently determining a final exposure level of an image capture device are described. A first camera generates a first image of a scene based on a first exposure level. A second camera generates a second image of the scene based on a second exposure level. When the first camera determines the first image includes out of range exposure, the first camera adjusts the first exposure level based on the second exposure level of the second camera. Additionally, the first camera adjusts the second exposure level of the second camera based on the second exposure level. Afterward, each of the first camera and the second camera are able to generate new images of the same scene using the updated first exposure level and updated second exposure level.

Abstract: Group transmission of data from a group of User Equipment devices to a network node of a cellular communication system where communication between devices is effected by device-to-device technology can provide significant improvements in uplink coverage and user bit rate. However, the benefits of group transmission means that not all devices of a group have sufficient network coverage to reliably receive a grant signal scheduling uplink resources from a network node. Methods, devices and a network node are proposed that enable the dynamic selection of either a direct grant mode, in which each device receives the uplink grant directly from the network, or a relayed grant mode, in which a device acting as group coordinator relays the grant to all members of the group, to ensure optimal performance for group transmissions. The selection is dependent on at least one determined condition relating to the group of devices and/or the group transmission.
