Abstract:
A method of compensating non-linearities in a collection of sampled digital values produced by an analog to digital converter having fat and thin digital codes, the method comprising the steps of:characterizing the analog to digital converter to identify the degree to which each digital code is either fat, thin or neither;digitizing an analog signal with the analog to digital converter to produce a collection of digital codes;detecting in the collection of digital codes occurrences of a selected fat digital code;replacing in the collection m-many out of n-many occurrences of the detected selected fat digital code with an adjacent digital code, m and n being integers related to the degree to which the selected fat digital code is fat; andgenerating an image corresponding to the input signal having intensity variations produced in accordance with digital codes in the collection thereof that have been replaced by the replacing step.
