Abstract
An input data processor selects a value indicated by change border data, and uses this value as a reference value for determining whether a predetermined process is effected, and to change the currently used value indicated by the change border data to another value when the value of the input data becomes equal to a predetermined value. Namely, when the value of the input data is in the vicinity of a specific value, the detection of a change of the input data can be effected by using a resolution smaller than another resolution used for the detection when the value of the input data is not in the vicinity of the specific value. Detection of a change of the input data can be efficiently performed. Further, the apparatus for processing input data may convert the input data into conversion input data so that the rate of a change in the value of the conversion input data in the vicinity of a specific value of the input data is larger or smaller than that of a change in value of the conversion input data corresponding to other input data having values which are not in the vicinity of the specific value. Thus, when the value of the input data is equal to a specific value, the rate of a change of the input data is increased or decreased. Thus, small or large resolution, can be used when the input data becomes equal to the specific value.
