ABSTRACT:
An image signal display device includes a program data readout circuit by which at least one second adjustment data, not to be adjusted, takes a proper value relative to a first adjustment data, to be adjusted, in accordance with a predetermined relational expression. A data calculating circuit calculates the second adjustment data, and a data changing circuit changes the second adjustment data together with the first adjustment data. A memory stores coefficient data of the relational expression and a digital-to-analog convertor converts an output signal read out from the memory into an analog signal that is fed to a display device for display as an image.
