Digital signal processing device.

摘要

Particularly (but not exclusively) for making adjustments to the label values of objects within an image being processed, the invention provides a device which receives a train of digital signals, identifies signal values within the train which are to be modified, and makes the appropriate modifications. The device comprises a multiple-route shift register arrangement which receives the train of signals and compares these values of each with a series of 'to be corrected' values and, on detection of correspondence, replaces them with 'correction' values in a third series.
