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 |
