Appeal No. 2001-1874
Application No. 09/072,758
BACKGROUND
The invention is directed to an image sensing array (ISA) having discrete and
continuous time processing capabilities. Representative claims 1 and 14 are
reproduced below.
1. An apparatus comprising:
a light sensitive element that generates a photocurrent related to an
incident light level;
an integration circuit coupled to the light sensitive element to compute an
average of the photocurrent during a sampling period to permit creation of a
digital image; and
a continuous time processing circuit coupled to the light sensitive element
to receive and process the photocurrent during at least a continuous segment of
time, the continuous time processing interpreting an aspect of the digital image.
14. A system comprising:
an image sensing array (ISA) having a plurality of pixels that form a focal
plane, the ISA having both continuous time processing capability and integration
capability, the continuous time processing to interpret an aspect of an image;
and
a memory coupled to the ISA to store a representation of an image
corresponding to light levels on a surface of the ISA during a sampling period.
