METHOD OF DIGITAL SIGNAL PROCESSING

A method of digitally processing images and/or audio in the form of a plurality of data samples, each data sample having a value representative of a visual or audio property, the method comprising: identifying a first set of data samples having values outside a first predefined range of data values; identifying a second set of data samples having values outside a second predefined range of data values, the second predefined range being within the first predefined range; and applying a non-linear scaling algorithm to the data values of the first and second sets of data samples to generate a set of modified data samples having data values within the first predefined range.
