Abstract
The present disclosure relates generally to apparatus and methods for image sensing, and, more particularly, to a multi-bit quanta image sensor (QIS) having a controllable (e.g., adjustably variable) exposure response characteristic. Some embodiments provide an apparatus and method wherein the non-linearity of the response of a multi-bit QIS is controllable (e.g., selectively variable) by dynamically choosing the bit depth n during AID conversion, and/or later (i.e., post-conversion) by firmware and/or software.
