The image forming apparatus includes a semiconductor laser that emits a laser beam, a light power of the laser beam being controllable by a current applied to the semiconductor laser; a scanner unit that exposes a photosensitive element by scanning the photosensitive element using the laser beam; a light power detection unit that detects a light power of the laser beam; a current control unit that controls the current applied to the laser based on the light power of the laser beam; a home position detection unit that detects whether the laser beam is positioned at a scan home position; and a continuous illumination unit that commences continuous illumination of the laser at a time which is prior to a forecast time at which the home position detection unit is forecast to detect the laser beam. | 2009-06-11 |
20090147069 | VWS SECURE/NON-SECURE BYPASS SWITCH - Disclosed is a secure/non-secure bypass switch, which includes a secure mode signal path, and a non-secure mode signal path, wherein signals are routed through an encryption device connected in the secure mode signal path when no power is supplied to the switch, and the signals are routed through the non-secure path when power is supplied to the switch. | 2009-06-11 |
20090147070 | PROVIDING PERSPECTIVE-DEPENDENT VIEWS TO VIDEO CONFERENCE PARTICIPANTS - During a video conference between a local endpoint and a remote endpoint, a display at the local endpoint may be configured to provide perspective-dependent views to local video conference participants. A local endpoint may receive a plurality of video streams and identify a first video stream that provides a first view of a remote participant and a second video stream that provides a second view of that participant taken concurrently from a different angle. A display at the local endpoint may display the first video stream at a first viewing angle that only allows the first view of the remote participant to be seen from a first region. The display may also concurrently display the second video stream at a second viewing angle that only allows the second view of the remote participant to be seen from a second region different than the first region. | 2009-06-11 |
20090147071 | Systems and methods of creating a virtual window - The systems and methods described provide an imaging system that allows multiple sensors to record images at their respective best exposures values and adaptively altering the exposure of the images recorded to create a seamless 360-degree view. In particular, the systems and methods described herein include determining exposure values for each column of photosensitive elements in a sensor by interpolating between the best exposure values of adjacent sensors. | 2009-06-11 |

20090147073 | Methods and Systems for Stereoscopic Three Dimensional Viewing - A method and system for three dimensional viewing of stereo images of an object or cavity includes using an imaging machine to obtain images representative of either a physical volume or a volumetric set of data. A computing machine can be used to identify image elements within the volumetric set of data by executing a ray tracing function to identify image elements along a path that is directed through the collection of images or sequentially ordered stack of images. The computing machine further applies a weighting function to intensity values related to the identified image elements. The computing machine generates at least one image element value based in part on the identified image elements, and based in part on the results generated from the executing of the ray tracing function and the application of the weighting function. Using the at least one image element value, the computing machine derives a pair of stereo images. Alternatively, the computing machine can select from within a collection of images representative of a physical volume, stereo pairs of images. The stereo pairs of images are displayed on a viewing apparatus. | 2009-06-11 |
20090147074 | Methods and Systems for Marking Stereo Pairs of Images - Systems and methods for marking stereo pairs of images include an imaging device for retrieving a collection of images that are representative of a volume, where the images can be representative of a physical volume or a volumetric set of data. A computing machine identifies image elements within the retrieved collection of images representative of a volumetric set of data, and further generates image element values that are based in part on the identified image elements. The computing machine further generates a stereoscopic pair of projection images having two members, where each member of the pair is based in part on at least one image element value generated by the computing machine. A viewing apparatus displays either the calculated stereoscopic pair of projection images or a pair of stereo images selected from images representative of a physical volume, such that when the pair of images are viewed through a portion of the viewing apparatus, the resultant display is a perceived three dimensional image. An input device or computer application is further used to position a marker within the stereoscopic pair of projection images to identify a location within the stereo pair of images. | 2009-06-11 |
