Designs and operational methods to increase the dynamic range of image sensors and APS devices in particular by achieving more than one integration times for each pixel thereof. An APS system with more than one column-parallel signal chains for readout are described for maintaining a high frame rate in readout. Each active pixel is sampled for multiple times during a single frame readout, thus resulting in multiple integration times. The operation methods can also be used to obtain multiple integration times for each pixel with an APS design having a single column-parallel signal chain for readout. Furthermore, analog-to-digital conversion of high speed and high resolution can be implemented.

In a 3rd Generation Partnership Project, 3GPP, communication system a base station comprises a scheduler allocating communication resource of at least one of a Physical Uplink Shared CHannel, PUSCH, and a Physical Downlink Shared CHannel, PDSCH to a User Equipment (UE). The scheduling may either be a dynamic scheduling wherein a resource allocation for a single frame is provided to the UE or a persistent scheduling wherein a resource allocation for a plurality of frames is provided to the UE. A resource allocator assigns resource of a Physical Uplink Control CHannel, PUCCH, to the UE dependent on whether dynamic scheduling or persistent scheduling is performed by the scheduler for the UE. The UE transmits uplink control data on a physical uplink channel which is selected as the PUCCH or the PUSCH in response to whether persistent scheduling is used for the UE. The invention allows e.g. reduced PUCCH loading.

A method for multiplexing a stream of stereoscopic image source data into a series of left images and a series of right images combinable to form a series of stereoscopic images, both the stereoscopic image source data and series of left images and series of right images conceptually defined to be within frames. The method includes compressing stereoscopic image source data at varying levels across the frame, thereby forming left images and right images, and providing a series of single frames divided into portions, each single frame containing one right image in a first portion and one left image in a second portion. Alternately, single frames may contain two right images in a first two portions of each single frame and two left images in a second two portions of each single frame, wherein each set of right and left images may be processed differently. Multiplexing processes such as staggering, alternating, filtering, variable scaling, and sharpening from original, uncompressed right and left images may be employed.

A group acknowledgment scheme permits a specified subset of a previously transmitted group of data frames to be acknowledged. In accordance with the preferred embodiment of the invention, a transmitting station sends a plurality of data frames to a receiving station and requests a single group acknowledgment frame from the receiving station, rather than an individual acknowledgment after each data frame.

A single frame format is employed by a millimeter wave communication system for single-carrier and OFDM signaling. A Golay-coded sequence in the start frame delimiter (SFD) field identifies the data transmission as single carrier or OFDM. Complementary Golay codes are employed in a channel estimation field to allow a perfect estimate of the multipath channel to be made. Marker codes generated from Golay codes are inserted periodically between slots for tracking and / or for reacquiring timing, frequency, and multipath channel estimates. The length of the marker codes may be adapted relative to the multipath delay spread.

A video processor that uses a low latency pyramid processing technique for fusing images from multiple sensors. The imagery from multiple sensors is enhanced, warped into alignment, and then fused with one another in a manner that provides the fusing to occur within a single frame of video, i.e., sub-frame processing. Such sub-frame processing results in a sub-frame delay between a moment of capturing the images to the display of the fused imagery.

A multi-dimensional database and indexes and operations on the multi-dimensional database are described which include video search applications or other similar sequence or structure searches. Traversal indexes utilize highly discriminative information about images and video sequences or about object shapes. Global and local signatures around keypoints are used for compact and robust retrieval and discriminative information content of images or video sequences of interest. For other objects or structures relevant signature of pattern or structure are used for traversal indexes. Traversal indexes are stored in leaf nodes along with distance measures and occurrence of similar images in the database. During a sequence query, correlation scores are calculated for single frame, for frame sequence, and video clips, or for other objects or structures.

Distributed computing environment (DCE) remote procedure calls (RPCs) are integrated with an advisory work load manager (WLM) to provide a way to intelligently dispatch RPC requests among the available application server processes. The routing decisions are made dynamically (for each RPC) based on interactions between the location broker and an advisory work load manager. Furthermore, when the system contains multiple coupled processors (tightly coupled within a single frame, or loosely coupled within a computing complex, a local area network (LAN) configuration, a distributed computing environment (DCE) cell, etc.), the invention extends to balance the processing of RPC requests and the associated client sessions across the coupled systems. Once a session is assigned to a given process, the invention also supports performance monitoring and reporting, dynamic system resource allocation for the RPC requests, and potentially any other benefits that may be available through the specific work load manager (WLM).

Scenes from motion pictures to be colorized are broken up into separate elements, composed of backgrounds / sets or motion / onscreen-action. These background and motion elements are combined into single frame representations of multiple frames as tiled frame sets or as a single frame composite of all elements (i.e., both motion and background) that then becomes a visual reference database that includes data for all frame offsets which are later used for the computer controlled application of masks within a sequence of frames. Each pixel address within the visual reference database corresponds to a mask / lookup table address within the digital frame and X, Y, Z location of subsequent frames that were used to create the visual reference database. Masks are applied to subsequent frames of motion objects based on various differentiating image processing methods. The gray scale determines the mask and corresponding color lookup from frame to frame as applied in a keying fashion.

A method and system dynamically calculates confidence levels associated with accuracy of Z depth information obtained by a phase-shift time-of-flight (TOF) system that acquires consecutive images during an image frame. Knowledge of photodetector response to maximum and minimum detectable signals in active brightness and total brightness conditions is known a priori and stored. During system operation brightness threshold filtering and comparing with the a priori data permits identifying those photodetectors whose current output signals are of questionable confidence. A confidence map is dynamically generated and used to advise a user of the system that low confidence data is currently being generated. Parameter(s) other than brightness may also or instead be used.
