Patent ID: 7719595

Claim:
A system for previewing an image, comprising: an image processor system that: receives an image signal for an image; amplifies said image signal at a higher current level and a lower current level; converts said image signal into a digital signal correspondingly having a higher data resolution level and a lower data resolution level; determines whether the image signal is to be previewed; in response to the determination that the image signal is to be previewed, selects the lower current level to produce a preview digital image at the lower data resolution level; and comprises an analog-to-digital converter (ADC) for converting said image signal into the digital signal correspondingly having the higher data resolution level and the lower data resolution level wherein the ADC has a total number of ADC stages and a number of the total number of ADC stages that are used is changed between providing the higher data resolution level and the lower data resolution level for the digital signal.
