Graphical input device

摘要

An input data display device makes it caster to input properly correlated relative corrections for a number of parameters. Relative amounts by which each of a number of parameters is to be adjusted can be displayed on the screen in a manner which shows their ranges and possible correlation. The data are input when the operator touches spots which he selects on the display screen. The pressure of his finger causes data to be generated which represent those input positions. A calculation device calculates output-ready relative correction values for the various parameters based on these input position data. These values are transmitted to connected device.
