Title: Method of flicker reduction
Inventor: OZGUR TASDIZEN
IPC: H04N5/235
Filed: 2017-11-30
Abstract: Applying flicker correction based on at least one region across a sequence of frames. The correction may remove “banding” artefacts and may be applied to High Dynamic Range (HDR) images. A sequence of frames of the video are captured, each frame comprising a plurality of predefined regions each comprising a plurality of pixels. A time-varying oscillation of the flicker is characterised based on variations in pixel intensities in at least one region across the sequence of frames. A flicker correction is applied to a frame of the video based on the oscillation of the flicker. A frame may be split into a plurality of zones, wherein a zone may be a flicker-free zone. The flicker correction may be inhibited in a flicker-free zone. An edge region of a flicker-free zone may be identified and a varying degree of flicker correction may be applied across the edge region between a first threshold 625 where no flicker correction is applied, and a second threshold 630 where a maximum correction 635 is applied. The amplitude, phase or frequency of the flicker may be determined. The video may be captured with a rolling shutter.

Title: Code realms
Inventor: JASON PARKER
IPC: G06F12/14
Filed: 2017-12-15
Abstract: A data processing system assigns software processes to realms. The memory of the system is divided into regions. The regions are assigned to realms, identified by a realm descriptor (RD). Each realm controls which other realms can access its memory regions. Memory regions holding shared code are assigned to a code realm. A process may execute code in a memory region assigned to its own realm. A process can also execute code in a region assigned to the code realm if the code realm authorization table (CRAT) for the realm to which the process is assigned indicates that execution of code in that region is permitted for that realm. A process may be prohibited from executing code in memory regions of other realms. A realm management unit (RMU) may keep a count of the number of realms with entries in their table for a given code realm. It may prevent invalidation of the code realm if there is such an entry.
