Selects between normal and backlit exposure modes. The
power-on default is normal mode. See Exposure Control
for full description
0
Selects between a linear (LIN=1) or gamma corrected
video signal on AVO. The power-on default is gamma cor-
rected.
1
Allows automatic gain control to be inhibited. The current
gain value selected is frozen. With AGC=0 a new gain
value can be written to the gain register via the serial inter-
face (header code 0101).
0
Allows automatic black calibration to be inhibited.
1
Allows automatic exposure control to be inhibited. The cur-
rent exposure value selected is frozen. Note that if auto-
matic exposure control is inhibited then automatic gain
control is also disabled. With AEC=0 a new exposure
value can be selected by writing to the coarse and fine
exposure registers via the serial interface (header codes
0011 & 0100).
0
Shuffles the read out of the horizontal shift register. Even
columns read out together then odd columns.
0
Shuffles the readout of the vertical shift register. Even
lines read out together then odd lines.
1
Requests a re-calibration of the black level while bit is low.
0
System clock division: (see Note)
0
0,0=1; 0,1=÷2; 1,0=÷4; 1,1=÷8
0
This bit must be set to 0 for correct sensor operation
0
Table 15 : Set-up code_1
Note: Decreasing the system clock rate proportionately increases sensor sensitivity (by increasing exposure time), but
also decreases frame frequency. System Clock must be x1 for standard CCIR or EIA framing.
