摘要： An ADRC circuit 3 generates spatial classes with SD data extracted by an area extracting circuit 2. A moving class determining circuit 5 generates a moving class with SD data extracted by an area extracting circuit 4. A class code generating circuit 6 generates a class code with the spatial class and the moving class. A tap decreasing ROM 7 supplies additional code data for each class code to a tap decreasing code 10. The additional code data is used to decrease taps of SD data. The tap decreasing circuit 10 decreases the SD data extracted by an area extracting circuit 9. A prediction calculating circuit 11 receives coefficient data corresponding to the class code from a ROM table 8 and obtains HD data with the decreased SD data corresponding to a linear prediction equation.

摘要： An amount-of-movement detection device which is capable of detecting the amount of movement with a high degree of accuracy when the amount of movement of an image is detected by hierarchical block matching method. An amount-of-movement detection device 1 forms image data S2.sub.n and S3.sub.n of plural hierarchies having different resolutions from each other, by input image S1.sub.n input at a first point in time, and forms multiplexed image data S2.sub.n-1 and S3.sub.n-1 of a higher hierarchy of low resolution, based on an input image S1.sub.n-1 input at a second point in time, by selecting pixels overlapping with each other from the image data of the lower hierarchy having higher resolution and reducing them in size, in order to detect a motion vector by block matching at a predetermined block unit for each of the hierarchies corresponding to the hierarchized image data S2.sub.n and S3.sub.n and the multiplexed and hierarchized image data S2.sub.n-1 and S3.sub.n-1. Thus, the accuracy in the detection of an amount of movement can be greatly enhanced.

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.
