CONTROL DEVICE FOR CATHODE-RAY INDICATOR Russian patent published in 2005 - IPC

FIELD: control devices for cathode-ray indicators.

SUBSTANCE: device has block of rectangular zones addresses, blocks of main point values along X and Y axes, interpolators, adders and analog-digital converters, noted goals are achieved by insertion of subtraction blocks and main points coordinates blocks along X and Y axes, block of zones diagonal lines angular coefficients, multiplier and comparison scheme. Higher precision of device is achieved because all blocks except for analog-digital converters are digital. Increase of image quality is achieved by separation of each rectangular zone on two triangular zones, to exclude gaps in interpolating surface. Laboriousness of adjustment is decreased by ordered positioning of interpolation node, to decrease their required number while keeping same interpolation precision.

EFFECT: higher precision, higher quality, lower laboriousness, higher efficiency.
