In a method for converting input analog signals to time signals and the time signals thus obtained to digital values, an arbitrary value is preset in a scaler as an offset prior to effecting a conversion and counting and the conversion and counting is effected by the time signals. A value the same as the preset value is digitally added, after the conversion and counting, to a counter in a direction in that the preset value is cancelled. The differential non-linearity is actually improved by varying the preset value every conversion and counting.
