摘要： A lighting controller is disclosed that automatically adjusts a lighting device based on user activity. The disclosed lighting controller processes at least one of audio and video information to identify predefined user events that suggest that a lighting device should be activated or adjusted. In one implementation, a number of behavior rules define various user activities or events that suggest that the user would like to activate or adjust a lighting device. Each rule contains one or more conditions, and, optionally, a corresponding action-item that should be performed when the rule is satisfied to activate or adjust the lighting device. Upon detection of a predefined event, the corresponding action, if any, is performed by the lighting controller.

摘要： A camera-based system includes a number of sites, each having a camera associated therewith. A processing system processes a video signal received from a camera at a given one of the sites, and provides a controlled switching between a representative presence mode and at least one other mode for presentation, at one or more of the sites remote from the given site, of corresponding output video associated with the given site. The processing system utilizes information derived from the video signal generated by the camera to control the switching between the representative presence mode and the other mode, which may be, e.g., a live video mode. For example, the processing system may process the video to identify a user of the system, retrieve a corresponding user profile, and control the switching between the modes in accordance with information in the retrieved user profile.

摘要： The present invention relates to a device containing an automatic zoom lens, and more particularly to a zoom lens that is controlled by a processor that is linked to a gaze tracking system. As a user looks onto an object through the device, the gaze tracking system collects data relating to the position of each eye of the user. This eye position data is input into the processor where the focal point of the user is determined. The processor then adjusts the zoom lens to zoom in or out onto the object based on either a predetermined or user input zoom factor.

摘要： A camera-based system implements a calibration procedure for determining, for a given system user, calibration information that characterizes the manner in which the user points within the system. The system directs the user to point separately at each point in a set of two or more points at different positions on a display. The system then detects, for each of the points pointed to by the user, a location of a pointing finger of the user in an image generated by each camera in a set of cameras of the system, such that for each of the points the location of the pointing finger and the corresponding point on the display specify a line. The lines associated with the points are then used to compute a reference point or other pointing direction calibration information for the user. The calibration information for the user may be stored with user-identifying information in a database of the system, and is utilized in subsequent pointing direction determinations for that user.

摘要： Briefly, an alarm system monitors the entry and exit of a fitting room. Various devices, including cameras for imaging, are used to scan customers as they enter and leave. Using image analysis, analysis of the audio signature of footfalls, and other criteria, the system attempts to match the images of customers leaving with stored images of customers entering. If no match can be found, an alarm signal is generated.

摘要： Barcode fragments of a barcode symbol to be read by an imaging-based presentation workstation are stitched together by capturing a plurality of images, each containing a barcode fragment and a plurality of features located adjacent to the barcode fragment. The features in each captured image are detected and matched. The barcode fragments are stitched together based on the matched features in the captured images. The barcode symbol is read from the stitched barcode fragments.

摘要： An image capture system for, and a method of, reading an optical code during a reading mode, comprise an aiming assembly including a laser for emitting a laser beam having a variable intensity, and for generating an aiming pattern from the laser beam during an aiming mode prior to the reading mode, and an imager for detecting and capturing an image of the aiming pattern and the code over a field of view by exposure over an exposure time period during the aiming mode, and for detecting and capturing an image of the code over the field of view during the reading mode. A controller is operative for controlling the intensity of the laser beam during the aiming mode by increasing the intensity of the laser beam during the exposure time period to enhance detection and capture of the aiming pattern by the imager, and by decreasing the intensity of the laser beam frame outside the exposure time period for user safety.
