Abstract
The disclosed architecture for an image sensor and the associated method employ an internal switching mechanism controlled by a much reduced number of shift registers to facilitate the readout of electronic signals generated by the photodetectors in the image sensor. The switching mechanism comprises resolution switches that can act sequentially or simultaneously so that image resolution can be controlled within the image sensor. Further, the overall performance of the image sensor is improved.
