摘要:
A pilot searcher for CDMA and GPS signals. In one aspect, the searcher is operated in conjunction with a sample buffer in a “real-time” or “off-line” mode. The writing/reading of samples to/from the buffer may be performed in a TDM manner via a common port, and samples may be decimated and packed prior to storing in the buffer. In another aspect, the overall search for pilots is partitioned into a number of tasks, with each task corresponding to a search over a given sample segment and based on a particular set of parameter values. The tasks may be stored in a queue and performed one at a time based on their order in the queue. Prior to performing a new task, the parameter values for that task is downloaded to a set of configuration registers. The parameters may be ordered and linked such that only new values are downloaded.

This disclosure describes techniques for detecting a barcode within an image. An image processor may, for example, process an image to detect regions within the image that may be barcodes. The image processor may identify regions of the image that exhibit a high concentration of edges and a high concentration of pixels with low optical intensity co-instantaneously as potential barcodes. The image processor may identify the regions using a number of morphological operations. The image processor may then determine whether the identified regions are actually barcodes by verifying whether the region have unique barcode features. The barcode detection techniques described in this disclosure may be independent of barcode size, location and orientation within the image. Moreover, the use of morphological operations results in faster and more computationally efficient barcode detection, as well as lower computational complexity.

An electronic device for parallel image processing using multiple processors is disclosed. The electronic device includes multiple image sensors for providing image data. The electronic device also includes multiple processors for processing segmented image data to produce processed segmented image data. Each processor is dedicated to one of the image sensors. A multiple processor interface is also included. The multiple processor interface maps the image data to the processors, segments the image data to produce the segmented image data and synchronizes the segmented image data to processor clock rates.

Present embodiments contemplate systems, apparatus, and methods to determine a user's preference for depicting a stereoscopic effect. Particularly, certain of the embodiments contemplate receiving user input while displaying a stereoscopic video sequence. The user's preferences may be determined based upon the input. These preferences may then be applied to future stereoscopic depictions.

A method, NodeB (320) and User Equipment (330) for TDD operation in a communication system operating in TDD mode in a frequency band allocated for FDD operation. Preferably, operation is in TDD uplink and downlink mode in a first frequency band designated or normally used for FDD uplink communication, and in TDD downlink-only mode in a second frequency band designated or normally used for FDD downlink communication. The invention provides the following advantages: Provides a flexible method to deploy a time division duplex architecture in frequency division duplex spectrum. Allows flexible use of system capacity by adjusting the uplink and downlink capacity split. Removes previous FDD duplex restrictions.

This disclosure describes an organizational scheme for memory that is useful for image processing. A memory controller architecture is also described, which takes advantage of the organizational scheme. The organizational scheme and controller architecture is particularly useful for high performance, high quality image processing of images that form a video sequence, but may also be applied in other image processing settings. The described techniques and organizational structure of the memory also allows the memory to be shared for other storage applications of a video device.

A method of combining data from multiple sensors is disclosed. The method includes receiving lines of image data at an image processor having an input for a single camera. Each line of the image data includes first line data from a first image captured by a first camera and second line data from a second image captured by a second camera. The method also includes generating an output frame having a first section corresponding to line data of the first image and having a second section corresponding to line data of the second image. The first section and the second section are configured to be used to generate a three-dimensional (3D) image format or a 3D video format.
