摘要： A method of correcting an image obtained by an image acquisition device includes obtaining successive measurements, Gn, of device movement during exposure of each row of an image. An integration range, idx, is selected in proportion to an exposure time, te, for each row of the image. Accumulated measurements, Cn, of device movement for each row of an image are averaged across the integration range to provide successive filtered measurements, G, of device movement during exposure of each row of an image. The image is corrected for device movement using the filtered measurements G.

摘要： Methods and systems for coded rolling shutter are provided. In accordance with some embodiments, methods and system are provided that control the readout timing and exposure length for each row of a pixel array in an image sensor, thereby flexibly sampling the three-dimensional space-time value of a scene and capturing sub-images that effectively encode motion and dynamic range information within a single captured image.

摘要： For deblurring an image, a method records both short-exposed pixels at a higher frame rate for a short-exposure region and normal-exposed pixels at a normal frame rate for full resolution. In addition, the method deblurs a normal-exposed image as a function of the short-exposed pixels and the normal-exposed pixels.

摘要： Techniques using small form factor infrared imaging modules are disclosed. An imaging system may include visible spectrum imaging modules, infrared imaging modules, and other modules to interface with a user and/or a monitoring system. Visible spectrum imaging modules and infrared imaging modules may be positioned in proximity to a scene that will be monitored while visible spectrum-only images of the scene are either not available or less desirable than infrared images of the scene. Imaging modules may be configured to capture images of the scene at different times. Image analytics and processing may be used to generate combined images with infrared imaging features and increased detail and contrast. Triple fusion processing, including selectable aspects of non-uniformity correction processing, true color processing, and high contrast processing, may be performed on the captured images. Control signals based on the combined images may be presented to a user and/or a monitoring system.

摘要： A contrast calculating unit calculates a contrast of a high frequency component and a contrast of a low frequency component of a transformed radiographic image at an analysis point set by an analysis point setting unit. A ratio calculating unit calculates a ratio of the contrast of the high frequency component to the contrast of the low frequency component. A determining unit determines whether or not there is a body motion during an imaging operation to take the radiographic image based on the ratio. A display control unit displays a result of the determination on a display unit.

摘要： A camera system includes a lens having a first shake correction unit for correcting shaking on the basis of the amount of shaking which is detected by a first shake amount detector and from which a first reference value corresponding to an output value of the first shake amount detector kept in a stationary state is subtracted, and a body having a second shake correction unit for correcting shaking on the basis of the amount of shaking which is detected by a second shake amount detector and from which a second reference value corresponding to an output value of the second shake correction unit in a stationary state is subtracted. The camera system corrects a first reference value or a second reference value.

摘要： A group point spread function (238) for a blurry image (18) can be determined by dividing the blurry image (18) into a plurality of image regions (232), estimating a region point spread function (234) for at least two of the image regions (232); and utilizing at least two of the region point spread functions (234) to determine the group point spread function (238). The group point spread function (238) can be determined by the decomposition of the estimated region point spread functions (234) into some basis function, and subsequently determining a representative coefficient from the basis functions of the region point spread functions (234) to generate the group point spread function (238).

摘要： In an example embodiment a method, apparatus and computer program product are provided. The method includes causing a screening element in a camera to block wavelengths associated with at least one color in incident light at pre-defined time intervals during an image frame capture. A motion blur is removed from the captured image frame for the at least one color based on the blocking of the wavelengths associated with the at least one color. The method further includes generating a motion deblurred image frame using the captured image frame with the motion blur removed for the at least one color.
