摘要： A field memory stores convergence adjusting data which corresponds to a plurality of points on a display screen. An interpolation calculation circuit creates interpolation convergence adjusting data for correction points located between adjacent adjusting points, using a plurality of adjusting data items and interpolation coefficients. The output of the interpolation calculation circuit is subjected to digital/analog conversion and passed through a low-pass filter, thereby forming a convergence correction signal. This correction signal is supplied to each deflection coil. At the time of creating interpolation adjusting data for a point located between adjusting points, an optimal interpolation coefficient is output from a ROM or a ROM, depending upon whether the point is included in the odd or even field.

摘要： NTSC convergence adjusting data corresponding to a plurality of portions on a display screen is stored in a data storage section in advance. Convergence adjusting data is stored in a field memory in a NTSC scanning mode. Adjusting data transferred to the memory is supplied to a vertical interpolation circuit, and interpolation adjusting data between the adjusting points is created using the plurality of adjusting data and interpolation coefficients. Data output from the vertical interpolation circuit is A/D-converted, and supplied to a deflection coil through a low pass filter as a convergence correction signal. In a PAL scanning mode, PAL convergence adjusting data is created with use of NTSC convergence adjusting data by a control microcomputer so as to be stored in the frame memory.

摘要： A digital convergence apparatus using two different kinds of data to correct the convergence of odd and even scanning lines, respectively. A first memory stores data for the convergence correction corresponding to plural correction executing points aligned in the horizontal or vertical direction of a screen. A first static convergence data memory stores a first static convergence correction data for correcting the entire screen in the same direction, a second static convergence data memory stores a second static convergence correction data different from the first static convergence correction data only by an amount corresponding to the distance between the scanning lines. Selecting means select the output of the first or the second static convergence data memory according to the odd field period or the even field period. Adding means add the output of the selecting means to the data stored in the first memory. Vertical interpolating means interpolate the output of the adding means in the vertical direction, and a convergence correction coil corrects the convergence based on the output of the adding means.
