20110050920 | METHOD, SYSTEM AND COMPUTER PROGRAM PRODUCT FOR REDUCING MOTION BLUR - The present invention relates to a method for reducing motion blur. According to the method, at least two image frames are captured. A sequence of values is provided. All captured frames are processed by subsequently associating one sequence value with each captured frame. The processed captured frames are accumulated and a deconvolution is applied to the accumulated frame. | 03-03-2011 |
20110199492 | METHOD AND SYSTEM FOR OBTAINING A POINT SPREAD FUNCTION USING MOTION INFORMATION - The present invention relates to a method and system for obtaining a point spread function for deblurring image data captured by an imaging device comprising a motion sensor. First, motion path values indicating the motion of the imaging device during the exposure time are acquired. The motion path values of the imaging device are then projected onto the sensor plane and for each sensor pixel the projected motion path values are integrated over time. Said integrated value represents for each sensor pixel an initial estimate of the point spread function. Optionally, the size of the point spread function can also be estimated based on the distance of the focused object and taken into account during the projecting step. | 08-18-2011 |
20110254983 | DIGITAL CAMERA AND METHOD FOR CAPTURING AND DEBLURRING IMAGES - The present invention proposes a digital camera and a corresponding method for capturing and deblurring images which remove several disadvantages of the prior art. In particular, the hardware limitation as well as the motion restriction of the known conventional MIP approach have been overcome. According to the proposed approach, image frames are electronically moved by an electronic frame shifting means. This allows a frame shifting in any type or fashion, wherein no complicated hardware arrangement is needed, as this has been required according to the known conventional MIP approach. The proposed deblurring approach is not limited to any type of frame shifting pattern, and it is furthermore not limited to a one-dimensional motion of the frames, as it also works for the case of a two-dimensional frame motion. Similar as in the conventional Motion Invariant Photography approach, the frame shifting results in a motion-invariant blurred image which can be deconvoluted by a single deconvolution. | 10-20-2011 |

20130278726 | IMAGING SYSTEM USING A LENS UNIT WITH LONGITUDINAL CHROMATIC ABERRATIONS AND METHOD OF OPERATING - A lens unit of an imaging unit features longitudinal chromatic aberration. From an imaged scene, an imaging sensor unit captures non-color-corrected first images of different spectral content. An intensity processing unit computes broadband luminance sharpness information from the first images on the basis of information descriptive for imaging properties of the lens unit. A chrominance processing unit computes chrominance information on the basis of the first images. A synthesizing unit combines the computed chrominance and luminance information to provide an output image having, for example, extended depth-of-field. The imaging unit may be provided in a camera system, a digital microscope, as examples. | 10-24-2013 |
