    摘要： A target-pixel-setting section (31) sets a target pixel in a target image to be predicted. A motion-direction-detecting section (32) detects a motion direction corresponding to the target pixel. A pixel-value-extracting section (36) extracts from peripheral images corresponding to the target image, in order to extract a main term that mainly contains component of the target pixel in a moving object that encounters a motion blur in the peripheral images, at least pixel values of pixels in the peripheral images whose space position roughly agree with space position of the target pixel. A processing-coefficient-setting section (37a) sets a specific motion-blur-removing-processing coefficient. A pixel-value-generating section (38a) newly generates pixel values for processing from the pixel values extracted by the pixel-value-extracting section (36) corresponding to the motion direction and generates pixel values corresponding to the target pixel based on the pixel values for processing and the specific motion-blur-removing-processing coefficients. It is possible to perform a robust motion-blur-removing processing on any shifts of motion vector.

    摘要： 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. An object which is moving at a movement amount v in the horizontal direction is photographed, and an image wherein the object is blurred is input into a signal processing device. A continuity setting unit supplies the movement amount v of the object to an actual world estimating unit as continuity information. The actual world estimating unit estimates a pixel value for an image without blurring, by computing a normal equation comprising a model equation which models the relation of the pixel values in the input image and the pixel values in an image without blurring according to the movement amount v, and a constraint condition expression which constrains between the pixels in an image without blurring, and supplies this to an image generating unit. The present invention can be applied to, for example, cases of removing movement blurring from an image, for example.

    摘要： An input picture signal having noise added through a transmission path or the like is supplied. Noise is removed from the input picture by a class categorizing adaptive process in which predictive coefficients are pre-learnt and decided for each class. A class corresponding to a noise component contained in the input picture is decided. Predictive coefficients of the class and the values of pixels of frames containing a considered pixel of the input picture signal are linearly combined. Thus, predictive pixel values are generated, which are free of noise. When motion of a considered pixel is detected and pixels that are used to decide a class and pixels that are used for a predictive calculation are compensated corresponding to the motion, noise accurately corresponding to a noise component can be removed from the input picture signal.

    摘要： Picture data of frames [−2] to [+2] of an input picture signal is stored to frame memories fm [−2] to fm [+2]. The picture data of the frame f [0] is supplied to an area extracting circuit. In addition, the picture data of each frame is supplied to a pixel extracting circuit. A horizontal direction DR calculating circuit and a vertical DR calculating circuit calculate a DR in the horizontal direction and a DR in the vertical direction, respectively, and determine the maximum values thereof. A voting range determining circuit and a voting range updating circuit perform a process for finally determining a voting range corresponding to the maximum value of the DR in the horizontal direction and the maximum value of the DR in the vertical direction and a process for designating a new area. A pixel extracting circuit extracts pixels on a straight line defined by straight line parameters. A dispersion calculating and straight line parameter holding circuit performs a process for calculating the dispersion of the extracted pixels, comparing the calculated values, and holding the calculated value and straight line parameters corresponding to the calculated value and a process for updating the straight line parameter. A straight line parameter voting circuit selects the maximum frequency of the supplied straight line parameters. A voting pixel updating circuit updates voting pixels.
