Abstract: A user interface unit sets a parameter based on operations of a user, and outputs to a parameter correction unit. The parameter correction unit extracts the feature quantity of pixels in an observation region that corresponds to the value of the parameter, and based on the maximal value of that feature quantity, corrects the parameter specified by the user as the correction parameter. A blurring correction unit corrects input image data based on the correction parameter, and generates image data of the image wherein the blurring has been corrected. The present invention can be applied, for example, to a digital camera.

Abstract: A shooting-information-detecting section detects shooting information from an image pick-up section. A motion-detecting section detects a motion direction of an image on an overall screen based on a motion direction of the image pick-up section contained in the shooting information. A processing-region-setting section sets a processing region in at least any one of a predicted target image and a peripheral image thereof, which correspond to a target pixel in the predicted target image. A processing-coefficient-setting section sets a motion-blur-removing-processing coefficient that corresponds to the motion direction detected in the motion-detecting section. A pixel-value-generating section generates a pixel value that corresponds to the target pixel based on a pixel value of a pixel in the processing region set in the processing-region-setting section and the processing coefficient set in the processing-coefficient-setting section. Motion-blur-removing processing can be accurately performed.

Abstract: The present invention relates to an apparatus for processing an image signal etc. that are well applicable to removal of coding noise from, for example, an image signal. Based on five consecutive frames of an image signal Va, a memory portion 121 outputs as pixel data xi of predictive taps plural items of pixel data located in a space directional and time directional peripheries with respect to a target position in an image signal Vb. In the case, frames before and after a current frame are subjected to motion compensation by using a motion vector. A class classification portion 124 obtains a class code CL indicating a class to which pixel data of the target position in the image signal Vb belongs, by using the pixel data xi and motion vectors BWV(0), BWV(−1), FWV(0), and FWV(+1). A calculating circuit 126 obtains pixel data y of the target position in the image signal Vb based on an estimation equation by using the pixel data xi and coefficient data Wi that corresponds to the class code CL.

Abstract: An image signal processing apparatus and method perform appropriate correction of image blurring in accordance with an image characteristic. In the apparatus, a user interface designates a blurring parameter, and a control signal generating unit generates a control signal corresponding to the designated parameter. An image characteristic detecting unit determines directions in which pixels in an input image have flat levels and directions in which pixels in the input image have levels corresponding to edges. Based on the determination, an address calculating unit reads coefficients from a coefficient ROM and supplies the coefficients to a product-sum calculating unit. The product-sum calculating unit generates a blurring-eliminated image by performing product-sum calculation using the coefficients. A post-processing unit produces an output image based on the input image and the result of product-sum calculation.
