摘要:
A signal processing device for learning operations made by a user, and for generating signal optimal to the user based on the learning results. A learning unit monitors supplied operating signals generated based on user operations, and judges whether to learn the operating signals. When the operating signals are to be learned, the learning unit learns a correction norm for correcting input signals, based on the learning operating signals and outputs the correction norm to a correcting unit. The correcting unit corrects input signals based on the correction norm and outputs the corrected signals as output signals. The present invention can be applied to an NR (Noise Reduction) circuit which removes noise.

A picture processing apparatus for generating an output picture signal with higher quality than the input picture signal. A first signal processor has a storage device for storing a picture signal with the same quality as the output picture signal. The input picture signal and the stored picture signal are added to generate a first picture signal with higher quality than the input picture, which is stored in the storage device. A second signal processor performs a class categorizing adaptive process by extracting a feature of the input picture signal corresponding to the position of a considered pixel of the output picture signal, categorizing the considered pixel as one of a plurality of classes corresponding to the feature, and calculating the input picture signal using a predetermined calculating method corresponding to the categorized class, thereby generating a second picture signal with higher quality than the input picture signal. One of the first and second picture signals is selected as the output picture signal.

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.

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.
摘要:
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.

摘要:
The present invention relates to a signal processing device and signal processing method, and program and recording medium, whereby images and the like closer approximating real world signals can be obtained. With regard to an input image of dimensions fewer than the dimensions of actual world light signals, wherein actual world light signals have been projected and a part of the continuity of the actual world light signals has been lost, actual world signals are estimated at an actual world signal estimating unit 10003 from the input image within a processing region set at a processing region setting unit 10001, corresponding to continuity set at a continuity setting unit 10002. On the other hand, information relating to at least one of processing region, continuity, and actual world signals, is supplied from a user I/F 10006 to the processing region setting unit 10001, continuity setting unit 10002, or actual world signal estimating unit 10003, according to user operations. The present invention can be applied to, for example, cases of removing movement blurring from an image, for example.
