    摘要： A compensation allocation unit performs allocation compensation of a motion vector to a pixel to which a motion vector is not allocated by a victor allocation unit. A C/UC area determination unit compares magnitudes of a present DFD, a past DFD, and a future DFD based on a background vector and a DFD based on a compensation allocation vector by an evaluation value calculation unit to determine an area of a target pixel. Regarding the target pixel determined as the pixel in a covered area or an uncovered area, an interpolation method decision unit decides a computation method for a pixel value through which one of a double-sided interpolation and a one-sided interpolation. An interpolation frame generation unit computes the target pixel of the pixel value of the interpolation frame through the method decided by the interpolation method decision unit.

    摘要： The present invention relates to an image processing device and method, a program, and a recording medium whereby the evaluation regarding the reliability of a motion vector can be performed even in the case of an average brightness level between frames changing greatly. On a frame t+1, a block B1 at the position shifted from a pixel p1 to which a pixel p0 on a frame t corresponds by the vector quantity of a correct motion vector v1, and a block B2 at the position shifted from the pixel p1 to which the pixel p0 corresponds by the vector quantity of an incorrect motion vector v2 are shown. Here, the movement of a light source or the like is performed upon the block B1 alone, and even if the brightness level of the block B1 decreases as a whole, determination is made that the evaluation value of the block B1 is high in reliability as compared with the evaluation value of the block B2 by employing the sum of squared brightness values from which the average brightness value within a computation block is subtracted for each frame as an offset. The present invention can be applied to a signal processing device for performing frame frequency conversion processing from a 24P signal to a 60P signal.

    摘要： The present invention relates to an image processing device and method, a program, and a recording medium whereby the detection precision of a motion vector by the gradient method can be further improved. A counter value computing unit 451 acquires the number of valid pixels, the number of pixels having no gradient in the horizontal direction, and the number of pixels having no gradient in the vertical direction from a valid pixel number counter 441, a no-horizontal-gradient counter 442, and a no-vertical-gradient counter 443, computes the ratio between valid pixels within a computation block and one-sided gradient pixels among the valid pixels, and controls the value of a flag which a flag setting unit 452 sets in accordance with the computation results. The flag setting unit 452 sets the value of a gradient flag, and outputs the gradient flag to the subsequent stage. At the subsequent stage, gradient method computation and vector evaluation processing are executed based on the gradient flag. The present invention can be applied to a signal processing device for performing frame frequency conversion processing from a 24P signal to a 60P signal.

    摘要： An adaptive dynamic range encoding method and device in which evaluation data mainly centered about the amount of the change in the spatial direction of picture data in a block is detected, and re-quantization is performed which will give a minimum value of the evaluation data. The re-quantization is performed at an optimum quantization step conforming to the picture in the block in such a manner that picture portions having the same level may remain at the same level after re-quantization. This renders it possible to eliminate quantization distortions from being produced in the reproduced picture.
