Embodiment Construction

[0027] The present invention relates to an optimal process and apparatus for generating a waveform from a sequence of waveform-determining factors, and is particularly suitable for recovering a waveform from a minimum number of samples with a minimum computational effort. The invention is applicable in a variety of situations, but here a digital convergence correction system is shown in which a matrix of factors for points spatially distributed on a display is stored and used to generate each Correction waveform for color raster.

[0028] The digital convergence system shown in Figure 1A generally includes: a convergence pattern generator; an amplifier for driving a convergence correction coil or deflection coil; a memory for storing correction constants and an interface with a microprocessor. The convergence system is used to determine and store a matrix of correction factors for each color raster position at a separation point in the display. The system determines additiona...

Abstract

A method for producing a plurality of successive output data values defining an output curve that approximates an input curve defined by a plurality of input sample values, the output data values having a higher sampling frequency than the input sample values, the method comprising the steps of: pre-emphasizing the plurality of input sample values; defining successive and overlapping intervals including at least three of the pre-emphasized input sample values; interpolating a plurality of the output data values in an interpolation interval by calculating a moving average of a linear interpolation curve based on the at least three pre-emphasized input sample values, each of the output data values being influenced by the at least three pre-emphasized input sample values; and, emphasizing differently the influence of the at least three pre-emphasized input sample values for determining different ones of the output data values in the interpolation interval, whereby the pre-emphasizing step brings the output curve controllably close to each of the input sample values and each incremental slope of the output curve varies smoothly between adjacent output data values.

Description

technical field [0001] The present invention relates to the interpolation of correction factors for points between discrete correction sample points, such as a matrix of points in an array or a series of spaced points along a line. The correction factor for a specific data point is determined by preprocessing the correction factors for the weighted segment data before and after the segment where the specific point is located. For segments of specific points, the preprocessing modifies the correction factors input into the second-order piecewise interpolation process, and smoothly approximates the ideal correction curve with fewer correction factors and minimal data processing operations. [0002] The invention can be used, for example, in display characteristic correction systems, such as digital convergence correction systems, which interpolate between points in a matrix of convergence correction points, for color CRT (cathode ray tube) displays, or up-converted image data, o...
