Embodiment Construction

[0015] Exemplary embodiments generally relate to methods of estimating a point spread function (PSF) of a blurred digital image using gyroscopic data. FIG. 1 discloses an exemplary method 100 for estimating the PSF of a blurry digital image. The exemplary method 100 and variations thereof can be implemented using computer-readable media carrying or having computer-executable instructions or data structures stored thereon. Such computer-readable media can be any available media that can be accessed by a general purpose or special purpose computer. By way of example and not limitation, such computer-readable media may include RAM, ROM, EEPROM, CD-ROM, or other optical disk storage, magnetic disk storage, or other magnetic storage devices, or may be used to Any other medium that carries or stores the required program code means and that can be accessed by a general purpose or special purpose computer. Combinations of the above should also be included within the scope of compute...

Abstract

The present invention discloses methods for estimating a point spread function of a blurred digital image. One example method includes capturing gyro data during an image exposure time, deriving gyro samples from the gyro data at predetermined gyro sampling times, calculating a motion vector field of the image at each gyro sampling time, approximating an overall image scene motion path by averaging motion paths of selected pixels in the image, and estimating the point spread function from the approximated overall image scene motion path.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 60 / 863,875, filed November 1, 2006, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to image processing. More particularly, embodiments of the invention relate to methods and systems for reducing blur in digital images. Background technique [0004] Image-capturing devices such as digital cameras have grown in popularity, in part due to their reduced manufacturing cost, improved overall quality, and especially as camera functionality has been embedded into other electronic consumer Assistant (PDA)). [0005] Image blurring due to erratic hand movement or the like during an image capturing operation is often unavoidable for inexperienced photographers or users with unsteady hands. This blurring in images is disappointing because it is inevitable and detracts from the imag...
