A method and system for determining camera positioning information from an accelerometer mounted on a camera. The accelerometer measures the orientation of the camera with respect to gravity. Orientation measurement allows user interface information to be displayed in a “right side up” orientation on a viewfinder for any camera orientation. Alternatively, an artificial horizon indicator may be displayed in the viewfinder. The accelerometer may also measure camera movement. Camera movement information together with camera orientation can be used to determine camera usage. Additionally, camera movement information can be used to determine a minimum shutter speed for a sharp picture.

A method and system deblurs images acquired of a scene by a camera. A light field acquired of a scene is modulated temporally according to a sequence of ons and offs. The modulated light field is integrated by a sensor of a camera during an exposure time to generate an encoded input image. The encoded input image is decoded according to a pseudo-inverse of a smearing matrix to produce a decoded output image having a reduced blur.

System and method for capturing images with reduced blur. An embodiment includes an image sensor to capture optical information, a shutter coupled to the image sensor, a motion sensor to measure movement of an electronic device, and a processor coupled to the image sensor, to the shutter, and to the motion sensor. The shutter initiates a capturing of optical information, and the processor controls a state of the shutter based on predicted future movements of the electronic device based on movement information from the motion sensor. The predicted future movements permit a determination of image capture time to reduce blur.

Object is to provide an inner-focusing type zoom lens system carrying out focusing by moving a portion of a first lens group suitable for an auto-focus SLR camera. A zoom lens system includes, in order from an object, a first lens group having positive refractive power, a second lens group having negative refractive power, and a third lens group having positive refractive power. Upon zooming from a wide-angle end state to a telephoto end state, a distance between the first and the second lens groups increases, and a distance between the second and the third lens groups decreases. The first lens group is composed of, in order from the object, a 1A lens group G1A having positive refractive power, and a 1B lens group G1B having positive refractive power. Focusing from infinity to a close-range object is carried out by moving only the 1B lens group G1B to the object.

A target is illuminated with illumination light for image capture by a solid-state imager of an imaging reader. Internal reflections of the illumination light at a window are minimized, if not eliminated, by configuring the window as a non-planar optical element operative for redirecting the internal reflections away from the imager to enhance reader performance.

Techniques described herein provide a method for improved image and video stabilization using inertial sensors. Gyroscopes, accelerometers and magnetometers are examples of such inertial sensors. The movement of the camera causes shifts in the image captured. Image processing techniques may be used to track the shift in the image on a frame-by-frame basis. The movement of the camera may be tracked using inertial sensors. By calculating the degree of similarity between the image shift as predicted by image processing techniques with shift of the device estimated using one or more inertial sensor, the device may estimate the portions of the image that are stationary and those that are moving. Stationary portions of the image may be used to transform and align the images. For video stabilization, the realigned images may be combined to generate the video. For image stabilization, the realigned images may be either added or averaged to generate the de-blurred image.

A digital camera delays the capture of a digital image after image capture has been requested until the motion of the digital camera satisfies a motion criterion. The digital camera thereby reduces image blur that would otherwise occur due to camera motion.

An image blur correction device 400 includes a pitching movement frame 405, a yawing movement frame 408, and a third group frame 462. The pitching movement frame 405 supports a third lens group G3 included in an optical system for performing image blur correction. The yawing movement frame 408 supports the pitching movement frame 405 to be movable in the pitching direction perpendicularly intersecting a second optical axis A2, within a plane perpendicularly intersecting the second optical axis A2. The third group frame 462 supports the yawing movement frame 408 to be movable in the yawing direction along an arc whose center is a rotational axis A3, within a plane perpendicularly intersecting the second optical axis A2.

An x-ray breast imaging system comprising a compression paddle in which the compression paddle comprises a front wall and a bottom wall. The front wall is configured to be adjacent and face a chest wall of a patient during imaging and the bottom wall configured to be adjacent a length of a top of a compressed breast. The bottom wall extends away from the patient's chest wall, wherein the bottom wall comprises a first portion and a second portion such that the second portion is between the front wall and the first portion. The first portion is generally non- coplanar to the second portion, wherein the compression paddle is movable along a craniocaudal axis. The x-ray breast imaging system also comprises a non-rigid jacket releasably secured to the compression paddle, the non-rigid jacket positioned between the compression paddle and the patient.

An arrangement for, and a method of, reducing image blur in response to motion of an imaging reader for imaging symbols to be read, employs an illuminating light assembly supported by the reader for illuminating a symbol with illumination light having an intensity level over an illumination time period, a solid-state imager supported by the reader and having an array of image sensors for capturing return light from the symbol over a field of view over an exposure time period, a motion sensor, such as a gyroscope or an accelerometer, supported by the reader for detecting the motion of the reader, and for generating a motion signal in response to the detected motion of the reader, and a controller operatively connected to the motion sensor, for dynamically controlling at least one of the time periods and the intensity level in real time in response to the motion signal to optimally image the symbol.

A fixed focal length lens has a focal length of a whole system shorter than a back focus. The fixed focal length lens includes an aperture stop, and an image-stabilizing lens unit that moves in a direction including a component of a direction orthogonal to an optical axis to reduce an image blur. The conditions of 0.1<f/|fis|<0.5 and −0.35<Dis/DL<0.25 are met, where f is the focal length of the whole system, fis is a focal length of the image-stabilizing lens unit, Dis is a distance from the aperture stop to a surface farthest from the aperture stop of the image-stabilizing lens unit, and DL is a distance from a first surface closest to an object side to a final surface closest to an image side of the fixed focal length lens. A sign of the distance is positive in a direction from the object side to the image side.
