摘要： An analog-to-digital converter converts a video signal into a digital video signal consisting of N bits and outputs the converted signal. A correction value memory stores correction data consisting of M bits which is used to correct the difference in luminance between display pixels on a display. A multiplier multiplies the video signal consisting of N bits output from the analog-to-digital converter by the correction data consisting of M bits stored in the correction value memory, and outputs a video signal consisting of L bits with which the difference in luminance between display pixels on the display is corrected.

摘要： In an update operation of uneven luminance correction values, a display area of a flat display is handled as if it is divided into a plurality of small areas A to I. Then, in one update operation of the uneven luminance correction values, the uneven luminance correction values are updated only for one of these small areas A to I. Therefore, by performing the update operation of the uneven luminance correction values the same number of times as the number (9) of the small areas A to I, the uneven luminance correction values for the whole display area of the flat display are updated.

摘要： A judging unit compares data in a dither table for each display pixel with a numerical value of low-order 2 bits of an input signal (12 bits) and outputs 1 to an adder when the numerical value of the low-order 2 bits of the input signal is larger than the data in the dither table, while outputting 0 to the adder in other cases. The adder adds the value outputted from the judging unit to an uneven luminance correction value read from a correction memory, so that the uneven luminance correction value is corrected. A multiplier multiplies the input signal by the uneven luminance correction value after the correction.

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 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.
