Figure 10 shows the integration and read out sequence for
the synchronous shutter. All pixels are light sensitive at the
same period of time. The whole pixel core is reset
Non Destructive Readout (NDR)
After a pixel is initially reset, it can be read multiple times,
without resetting. The initial reset level and all intermediate
signals can be recorded. High light levels saturate the pixels
quickly, but a useful signal is obtained from the early
samples. For low light levels, one has to use the later or latest

samples. Essentially an active pixel array is read multiple
times, and reset only once. The external system intelligence
takes care of the interpretation of the data. Table 11
summarizes the advantages and disadvantages of non
destructive readout.
