Abstract

This paper presents new image sensors with multi- bucket pixels that enable time-multiplexed exposure, an alter- native imaging approach. This approach deals nicely with scene motion, and greatly improves high dynamic range imaging, struc- tured light illumination, motion corrected photography, etc. To implement an in-pixel memor y or a bucket, the new image sen- sors incorporate the virtual phase CCD concept into a standard 4-transistor CMOS imager pixel. This design allows us to create a multi
