Abstract
An image sensor includes a set of at least two pixels each sensing light of a same color coupled to a signal converter. A driver simultaneously turns on a respective switching element for transferring a respective photocurrent from a respective photodiode within each of such pixels to the signal converter, for capturing a moving image. Alternatively, the driver separately turns on the respective switching element for sequentially transferring a respective photocurrent from a respective photodiode within each of such pixels to the signal converter, for capturing a still image.
