摘要： The presence or absence of outside light is individually decided with respect to each of the time of executing AFE adjusted value acquiring processing, the time of executing LED adjusted value acquiring processing and the time of executing black correction data acquiring processing. In the case of deciding that the outside light is present, a parameter in the case of deciding that the outside light is present is modified to a predetermined value or a reacquired value. As a result of this, even when an incident state of outside light changes at the time of acquiring each of the parameters, it can properly be switched whether or not their parameters are replaced with the predetermined value or the reacquired value.

摘要： A computer controlled engraving system having a non-volatile memory (40) loaded with error coefficients. The error coefficients represent previously experienced differences between computed cell configuration values and corresponding configuration values for cells actually engraved. Sets of error coefficients are tabulated and stored in the memory (40) along with associated setup parameters. Setup of the engraving system for a new job is swiftly accomplished by using values of the setup parameters to retrieve sets of approximate error coefficients, from which interpolated values are obtained. The interpolated values of the error coefficients then are used for calculating configuration control parameters such as AC gain, video gain and white offset.
