摘要： A coded light component is modulated into emitted light on one of multiple channels each having a different modulation frequency. Modulation in the light causes a receiving camera to experience an apparent temporal frequency due to sequential capture of multiple frames and an apparent spatial frequency due to sequential exposure of spatial portions within each frame. Each channel can be detected by a detection module of the camera based on a respective combination of values of the apparent temporal and spatial frequency corresponding to the respective modulation frequency. The detection module has a respective response on each channel that varies as a function of the apparent temporal frequency. The channel for modulating the coded light component is selected from amongst a predetermined set having a property that the response of the detection module on each channel will have a minimum substantially at the apparent temporal frequency of each other channel.

摘要： A method for calibrating an ambience lighting system for providing an ambient light effect for a cinema display screen is proposed. The method is based on implementing the ambience lighting system in the form of one or more of coded light (CL) sources. The method then includes processing one or more images of a scene being illuminated by the ambience lighting system to determine, based on the CL embedded into the light output of the individual CL sources, color and/or an intensity of the light generated by the individual CL source. The set of control data for controlling the CLsources to provide the desired ambient light effect is then based not only on the color and/or intensity of image content to be displayed on the cinema display screen, but also on the determined color and/or intensity of the light output of the individual CL sources.

摘要： A system for determining a distance to an object comprises an image capture device (101) which has a coded aperture and an image sensor which is positioned out of a focus plane of the coded aperture. A receiver (103) receives an image of a scene from the image sensor and a detector (105) detects at least two image objects of the image corresponding to ghost images of the object resulting from different openings of the coded aperture in response to an optical characteristic of the object. A distance estimator (107) then determines a distance to the object in response to a displacement in the image of the at least two image objects. The distance may be to a person and the image may be a bright pupil image wherein pupils are enhanced by reflection of light by the retina. The image may be compensated by a dark pupil image of the scene.

摘要： A system is provided for determining the position of an interventional device inside a lumen. The interventional device comprises a distal portion inside the lumen and a proximal portion outside the lumen and the system comprises a processor. The processor is configured to receive a first estimated position of the distal portion of the interventional device inside the lumen from a first system and receive an estimated displacement of the distal portion of the interventional device inside a lumen from a second system, wherein the estimated displacement is representative of the movement of the distal portion of the interventional device inside the lumen. The processor is further configured to determine a second estimated position of the distal portion of the interventional device inside the lumen based on the first estimated position and the estimated displacement.

摘要： There is provided a system (100) for imaging a fundus of an eye (102). The system comprises an imaging sensor (104) configured to be aimed towards the subject to acquire an image of the fundus and a light interceptor (106) comprising an aperture. The light interceptor is positioned on an optical axis between the imaging sensor and eye at a point at which an image of the pupil aligns with the aperture and is movable relative to the optical axis to selectively block light passing from the eye to the imaging sensor. The system comprises one or more processors (108) operably coupled with the imaging sensor and the light interceptor, configured to detect movement of the pupil in the image and control the light interceptor to move relative to the optical axis in response to the detected movement to maintain alignment of the image of the pupil with the aperture.
