High dynamic range imager system

摘要

An imaging system configured to capture an image is provided, the imaging system including a high dynamic range imager configured to capture at least one high dynamic range image, and circuitry, wherein scheduling tasks within a row time interval is arranged to permit sharing of circuits used for correlated double sampling with selective reset tasks and with pixel readout tasks, and wherein scheduling tasks within a row time interval is arranged to permit sharing of comparator with selective reset tasks and with pixel readout tasks, while also providing at least one selectable integration period for which the integration period is adjustable and set to substantially less than a row time interval.

1. A high dynamic range imaging system configured to capture a high dynamic range image, the imaging system comprising:
an image sensor comprising:
an array of pixels; and circuitry in electrical communication with each pixel of said array of pixels; wherein said circuitry is configured to independently select one integration period from a set of available integration periods for substantially each pixel of said array of pixels, wherein said circuitry is further configured to conditionally reset a pixel of said array of pixels when a longest available integration period is not selected, wherein said circuitry is further configured to substantially sequentially readout pixels of said array of pixels, wherein said circuitry is further configured to perform said conditional reset during a blanking period of said readout.
