Imaging system and method for increasing the dynamic range of an array of active pixel sensor cells |
摘要 |
The dynamic range of an imaging system that utilizes an array of active pixel sensor cells is substantially increased by reading each cell in the array multiple times during each integration period. Each time a cell is read, the number of photons collected by the cell is saved and the cell is reset if the cell would normally saturate by the end of the integration period. At the end of the integration period, the number of photons collected by each cell is defined by the sum of the values collected during the integration period.
