Appeal No. 96-1628
Application No. 08/167,617
In the third embodiment a programmable filter replaces
the programmable attenuator, but functions the same way. In
particular, (Specification, page 12, lines 23-32)
in order to step down the output signal for sense
elements in the image sensor 33 for which the
incident light exceeds the predetermined value, a
programmable filter 52 is provided. The control
signals C /C output by the threshold detector 46 are
1 2
used to cause the control circuitry 52C of the
programmable filter to adjust the transmission
coefficients for those areas of the filter at which
the intensity exceeds the aforementioned
predetermined value. The programmable filter is
preferably implemented in the form of a liquid
crystal display, or the like, where individual
elements in the display can be set to different
transmission values.
Similarly, the next embodiment (Specification, page 12, lines
33-37) includes programmable attenuator 48, as in the first
embodiment.
In further embodiments, programmable attenuators 68,
control circuitry 51C in combination with control logic 62,
and programmable filter 52, are described to be the same as
and/or to function primarily the same as programmable
attenuators 48, control circuitry 51C in combination with
control logic 62, and
