Application No. 09/667,826
multiplex control signals SELECT1, SELECT2 . . . SELECTM which are provided
to respective output switches 122 (col. 9, lines 37-46).
21. Still referring to FIG. 2, compensation for nonuniformities in the
detector elements in each pixel can be achieved by offset correction circuitry in
each readout cell 100, described below, controlled by offset correction logic 130
(col. 10, lines 3-6).
22. Additionally, the offset correction control logic 130 may provide an
optional timing signal RST illustrated as being provided along line 140, for use in
the optional embodiment described below in relation to FIG. 3B (col. 10,
lines 27-30).
23. Referring to FIGS. 3A and 3B, the readout cell circuitry
corresponding to an individual readout cell 100 of FIG. 2 is illustrated in an
implementation employing microbolometer detector elements. More specifically,
FIG. 3A illustrates a readout cell employing a preferred approach to biasing of a
microbolometer detector element while FIG. 3B illustrates the readout cell of FIG.
3A further including a nonuniformity correction circuit, in accordance with the
present invention (col. 11, lines 19-27).
