Abstract
A system and method of processing raw image pixel information includes an integrated decimation filter and raw image scaling filter. The decimation filter operates in the time domain; for example, to calculate a weighted average of time samples. The raw image scaling filter operates in the spatial domain; for example, to calculate a weighted average of spatial samples. The raw image pixel information is modulated by a sigma-delta analog-to-digital modulator.
