摘要： An image processing apparatus is provided which performs image restoration as necessary while a computing processing burden based on an image restoration algorithm is reduced. RAW data of a blurred image is input to an RGB interpolation section. The RGB interpolation section generates an R component image, a G component image, and a B component image based on the RAW data. The G component image is input to an image restoration processing section and the R and B component images are input to an RGB to YCC section. The image restoration processing section performs an image restoration process based on a predetermined image restoration algorithm by using a PSF image representing a predetermined point spread function.

摘要： An image processing apparatus is provided which executes image restoration processing by performing a iterative computation on a degradation image. The image processing apparatus is capable of maintaining the quality of a restored image and completing the iterative computation sufficiently quickly. The first image restoration processor creates a first restored image f1 for a degradation image g by calculating an inverse filter H−1 based on Fourier transform H of a deterioration function h, multiplying the inverse filter H−1 and Fourier transform G of the degradation image g, and performing inverse Fourier transform on the result of the multiplication. The second image restoration processor creates a second restored image f2 by a iterative computation using the first restored image f1 and the deterioration function h.

摘要： An image deteriorated by camera shake, or the like, is restored in a short period of time. A ∇J computation section computes an evaluation value J from a deteriorated image G captured by means of photographing, a restored image F, and a PSF computed from an angular velocity detected by an angular velocity sensor, and further computes ∇J. When the square of norm of ∇J exceeds a threshold value, there is iterated processing for computing a new, restored image F by means of subtracting ε·∇J from the restored image F. A convergence parameter computation section sets the convergence parameter ε as a value which first shows an increase and subsequently a decrease depending on the number of iterations, thereby increasing the speed of convergence and inhibiting divergence.

摘要： An image processing device that produces a restored image that gives people natural feeling when a shot image with longer exposure time on the way to image blurring due to hand jiggling or an end portion is restored. The image processing device comprises an image processing unit that produces a restored image approximated to an original image from an object image to be processed, which is fluctuated against the original image due to movement of an image shooting device during exposure. The image processing unit produces the restored image while making the restored image correspond to a position having the longest exposure time for an object image to be processed.

摘要： A signal processing device, which is more practical for restoring signals, includes a signal processing unit for processing a signal. The processing unit produces restored data that approaches the original signal data before fluctuating (before blurring) by repeating the following processing: generating comparison data Io′ from arbitrary signal data Io by using information data G regarding fluctuation factors that triggers signal fluctuation; comparing the comparison data Io′ with original signal data Img′ as an object to be processed thereafter; producing restored data Io+n by allocating difference data δ to the arbitrary signal data Io while using the information data G regarding fluctuation factors; and substituting the restored data Io+n for the arbitrary signal data Io thereafter.
