High dynamic range image sensor system and method thereof

摘要

A high dynamic range imager system is provided that includes an imager having a pixel array, and memory in communication with the pixel array, the memory comprising a plurality of memory cells, wherein the number of memory cells is approximately the number of whole row-times of exposures between the first conditional reset and row readout.

1. A high dynamic range imager system comprising:
an imager comprising: a pixel array disposed on a die comprising a plurality of pixel rows; a memory disposed on the die and in communication with the pixel array, the memory comprising a plurality of memory cells configured to store data representative of a selected conditional reset; a memory manager in communication with the memory and configured to allocate a portion of the memory cells to each pixel row of the plurality of pixel rows at a time of a conditional reset of each pixel row, wherein the number of memory cells is based upon an exposure time between a first conditional reset and a row readout of each pixel row.
