so as to bypass the signal modifier 49 and to emerge
from the programmable attenuator unamended.
In a second embodiment (Specification, page 12, lines 5-
19), element 46, a threshold detector, is the same as in the
first embodiment, and therefore outputs control signals C and
1
C according to the incident intensity. Further, as shown in

Figure 8, the signals are directed to control circuitry 51C,
which
(Specification, page 12, lines 15-19).
change[s] dynamically the integration times of the
sense elements in the image sensor 51 so as to step
down the image signals output by the image sensor 51
corresponding to elements in the image sensor at
which the incident light intensity exceeds the
predetermined intensity value.
In other words, the control circuitry in the second embodiment
functions the same way as the programmable attenuator in the
first embodiment, thereby reducing the voltage level only for
intensities exceeding the threshold.
