Disclosed are a sort processing method and a sort processing apparatus, which, in a computer or data processing, compare magnitudes of pieces of data input by hardware, rearrange the pieces of data in accordance with a predetermined order and output the rearranged pieces of data. The sort processing apparatus includes first basic cells, each of which is composed of a first data comparator for comparing magnitudes of pieces of input data with each other and for outputting a first select signal, and a first data selector for rearranging said compared pieces of input data in a magnitude order on the basis of said first select signal, wherein said first basic cells having the same number as that of combinations of pieces of input data to be compared are arranged in a pipeline configuration.

An editing system includes an editing device for editing a plurality of channels of video data, a disk recorder constituted by a disk array having a plurality of disks, and a computer The disk recorder prepares a block map for managing recording areas on the disks so that respective subblock data are recorded at such position that a rotational delay time of a head becomes minimum in accessing the subblock data recorded on the respective disks. The disk recorder then divides pixel data of source video frames into a plurality of subblocks for each frame on the basis of the block map, and records the subblocks so that the subblocks are dispersed on a plurality of different disks.

An image display controller includes a first memory for storing data of an image to be displayed in a first window; a second memory for storing data of an image to be displayed in a second window, where no data is read from the second memory for image display during the data reading operation in the first memory; and a third memory for storing data of an overlay image on which the image of the first or second memory is superimposed, and also storing window data to set the range of the windows. The controller is arranged to prevent any disordered display of images and is capable of displaying an increased number of windows.

A method and apparatus for shading images by approximating a three-dimensional curved surface for computer graphics. Shading of a two-dimensional surface is provided by varying pixel brightness values to indicate a depth dimension of the two-dimensional surface. A plurality of polygons are employed, with each polygon being used to approximate a portion of the curved surface. A coordinate grid is provided extending in horizontal and vertical directions. The polygons are plotted on this coordinate grid. Coordinate grid points of the coordinate grid each represent respective pixels whose brightness is to be varied for the graphics. Scanning occurs across scan lines in a horizontal direction across the grid from grid point to grid point. Vertices of the polygons are provided on the coordinate grid, which vertices may not necessarily lie directly on a grid point. Brightness values at each vertex of the polygon are provided. Using these brightness values, by a process known as sub-pixel addressing, brightness values at the pixels at the grid points of the coordinate grid lying inside of the polygons are determined by linear interpolation based on brightness values at locations where pixels are not provided on sides of the polygon.
