Appeal No. 96-1628
Application No. 08/167,617
The appellant's invention relates to a video camera which
reduces by a constant amount (a negative offset) the voltage
level of the video signals which correspond to an incident
intensity over a predetermined threshold. Claim 1 is
illustrative of the claimed invention, and it reads as
follows:
1. Image capture apparatus for producing video
image signals, comprising:
image sensor means for producing video image
signals having voltage levels representative of
radiation intensities incident on respective areas
of said image sensor means;
means for identifying those respective areas of
said image sensor means at which the incident
radiation intensity exceeds a predetermined
intensity and for producing a control signal
representative thereof; and
means responsive to said control signal for
selectively causing a reduction in the voltage
levels of said video image signals corresponding to
said respective areas, which reduction is equivalent
to applying a negative offset to said video image
signals.
