摘要： A past frame at a past time has a motion vector in a block, and a reference frame at a reference time has a different block which is a motion-compensated block identical in position to a terminal point of a motion vector in the block. When a gradient method is used to detect a motion vector in the different block in the reference frame, a motion vector which is identical in magnitude and orientation to a motion vector and whose initial point is the different block in the reference frame is used as a candidate vector for initial vectors. The present invention is applicable to a signal processing apparatus for performing frame frequency conversion 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 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： For each pixel in an operation block, an effective pixel determining unit sets a predetermined pixel difference (threshold value) on a time-base pixel difference. When the time-base pixel difference is less than the set predetermined pixel difference, it is determined that the pixel contributes to (or are effective in) motion vector detection, and uses the pixel in the gradient method in the case of performing motion vector detection. When the time-base pixel difference is not less than the set predetermined pixel difference, it is determined that the pixel is regarded as having a possibility to generate irregularity in movement, and the pixel is excluded from the gradient operation in the case of performing motion vector detection. The present invention is applicable to a signal processing apparatus for performing frame frequency conversion from a 24 P signal to a 60 P signal.

摘要： Conventionally, to code a digitized image signal, a corresponding quantity of information is allocated to an edge part for carrying out coding, and therefore reduction in the quantity of information is limited, deteriorating the coding efficiency. Thus, an evaluation section of an encoder evaluates the characteristics (strength of correlation between pixels) of an image using a predetermined evaluation function, and decides a transmission pixel in accordance with the characteristics, consequently deciding a random scan order. A differential coding section differentially codes the image on the basis of the scan order decided by the evaluation section. A multiplexing section multiplexes the differential coding output from the differential coding section.

摘要： A delay register section 31 holds SD pixels of a luminance signal and a classification section 33 decides a class, reads a coefficient corresponding to the decision result from a coefficient RAM section 40, and outputs the coefficient to a product-sum section 38. The product-sum section 38 captures the pixel data for 17 taps from the delay register section 31, converts the pixel data into seven taps, and outputs them to the product-sum section 38. The product-sum section 38 performs the product-sum operation of pixel data and coefficients and outputs the operation result as HD pixels. An interpolation pixel operation section 42 applies a simple interpolation processing different from the case of a luminance signal to the pixel data of a color signal component to generate HD pixels of a color signal. Thus, downsizing and cost reducing can be realized.

摘要： Apparatus and methods are provided for producing a zoomed image signal from an input image signal. The input image signal is separated into a number of block signals each representing a subarea of the input image. Class codes are produced based on the block signals. Each class code identifies predetermined image data of a zoomed image portion which corresponds to the subarea represented by the block signal on which the class code is based. The predetermined image data is generated in response to each class code. Shifted display positions are assigned for image data of the selected block signals, and the zoomed image signal is synthesized from the image data having shifted display positions and the predetermined image data such that the predetermined image data are assigned display positions intermediate the shifted display positions of the other data.
