Abstract: Network on Chips (NoC)s with a bufferless and nonblocking architecture are described. Core processors are communicatively coupled together on a substrate with a set of routing nodes based on nonblocking process. A network component routes data packets through the routing nodes and the core processors via communication links. A bufferless cross bar switch facilitates the communication of the data packets and/or path setup packets through the communication links among source processors and destination processors. The communication links include one or more channels, in which a channel comprises a data sub-channel, an acknowledgement sub-channel and a release sub-channel.

Abstract: Based on image data input to a display unit and an image on a display surface acquired by an acquisition unit, control is performed to decrease the difference between the input image data and the image displayed on the display surface.

Abstract: An apparatus and method to track and to photograph a mobile object over a wide range, by a cooperative operation of multiple cameras. In addition, a mobile tracking system is provided for tracking the mobile object by the cooperation of multiple cameras, in which each camera includes a photographing device which photographs and recognizes the mobile object, a changing device which changes a view angle of the photographing device, a position deriving device which derives a position of the camera, a distance deriving device which derives the distance between the camera and the mobile object, and a communication device which transmits an identifier of the camera, a position of the camera, a moving direction of the mobile object and the distance between the camera and the mobile object to another camera and receives an identifier of the other camera, a position of the other camera, a moving direction of the mobile object and a distance between the other camera and the mobile object from the other camera.

Abstract: An image sensor includes: image capturing pixels and focus detection pixels disposed together on a single substrate; and adjacent pixels that are not equipped with a photoelectric conversion unit and are disposed adjacent to the focus detection pixels.

Abstract: This invention realizes high-precision exposure regardless of the F-number of an image sensing lens in photography. One pixel includes a first light-receiving region (119c) which includes a region where the principal ray of an image sensing lens is incident, and second light-receiving regions (119a, 119b) which do not include the region where the principal ray of the image sensing lens is incident. The first light-receiving region (119c) is sandwiched between the two second light-receiving regions (119a, 119b).

Abstract: Optical projection systems for the display of electronic images often suffer from degraded image quality due to color field registration errors caused by lateral chromatic aberration. Although most projection lenses are partially corrected for lateral chromatic aberration during the design process, the uncorrected residual aberration limits the imaging performance of many projection displays, especially when displaying text and graphics with single-pixel-wide features. Some embodiments of the invention correct color field registration errors due to lateral chromatic aberration in multiple-imager projection systems. Other embodiments of the invention correct radial distortion and keystone distortion in single-imager and multiple-imager projection displays. In some embodiments of the invention, the imager(s) pixel geometry is arranged to compensate for optical aberrations, which result from the optical system so as to achieve a corrected image.
