IMAGE SIGNAL CONVERSION WITH EXTENDED PRECISION AND DYNAMIC RANGE

摘要

A signal is generated at a source (100a) and a first portion of the signal (108a) is processed locally by a processor (110a). This first portion of the signal (108a) that is locally processed, is comprised of data, which would be prone to noise masking or loss, in its transition from the source (100a) to a non-local analog-to-digital converter (114a) in the absence of a processing step. The remaining portion of the signal (104a) is converted at a non-local analog-to-digital converter (106a), to produce a first digital signal. The processed signal (112a) is converted non-locally at a non-local converter (114a) to produce a second digital signal. Finally the first digital signal is combined with the second digital signal (116a) to produce a digital output signal (118a).
