An embodiment may include a display processor, memory to store a 2D frame corresponding to a projection from a 360 video, and a quality selector to select a quality factor for a block of the 2D frame based on quality information from neighboring blocks of the 2D frame, including blocks which are neighboring only in the 360 video space. The system may also include a range adjuster to adjust a search range for the 2D frame based on a search area of the 2D frame, a viewport manager to determine if a request for a viewport of the 2D frame extends beyond a first edge of the 2D frame and to fill the requested viewport with wrap-around image information, and/or a motion estimator to estimate motion information based on both color information and depth information. Other embodiments are disclosed and claimed.

A near-infrared sensitive video camera comprises a control unit configured to: dynamically detect a setting of the camera, the setting being one or more of: a zoom level, a focus setting and a setting of an IR-illuminator of camera. The control unit dynamically acquires a gain setting map for an image sensor, the acquired gain setting map being associated with the dynamically detected setting of the camera and comprising individual gain settings of the image sensor. Dynamically acquiring the gain setting map comprises accessing a database of gain setting maps associated with specific settings of the camera and on the dynamically detected setting of the camera; and dynamically adjusting a gain setting of the image sensor based on the acquired gain setting map.
