<p>The present invention provides an improved imaging device having high dynamic range and various apparatuses incorporating these high dynamic range imaging devices In a preferred design embodiment, row parallel processing is incorporated to read a signal indicative of the light induced charge for each pixel of the row, to compare the indicated level of the light induced charge against a threshold level for each pixel of the row, to, for each pixel of the row, interrogate the memory record of the reset condition, to determine whether or not to reset each pixel of the row based on the result of the comparison, the memory indication and the stage in the readout sequence, to store an updated record of the partial reset history, as required, for each pixel of the row, and finally to conditionally reset each pixel of the row based on the above information for the respective pixel.</p> |
