ABSTRACT:
An apparatus for applying a curve transfer function to an input signal comprises a first set of memory for storing values representing boundary points or distance differences along a curve of the transfer function, a second set of memory for storing slope values of lines connecting adjacent boundary points along the curve, a counter unit for maintaining a position count indicating position along the curve of the transfer function with respect to the stored boundary point values, an addressing unit, responsive to the position count, for selecting, from the second set of memory memory, the slope value corresponding to the position count, an accumulator for adding the selected slope value to an accumulator output value; and a comparator and data latch for determining when the accumulator output value corresponds to the input signal, and for selecting the corresponding accumulator output value as an output signal representing the application of the curve transfer function to the input signal.
