Level correction between sensor
taps
Since XCL-S600/S600C and XCL- S900/S900C have a
CCD with 4-channel signal outputs, output level
differences may occur during channel reading due to the
characteristic difference between channels. Level
correction between sensor taps can correct the level
differences. A command for one-push (automatically
detecting the level difference and adjusting only once),
continuous (constantly detecting the level difference and
adjusting continuously), and manual correction
(correcting left and right manually) is provided. After
one-push is performed once, the state returns to manual
designation.
Manual designation is performed by the BL-ADJ-1/2
command. The left screen is for TAP1 and the right
screen is for TAP2. One push and continuous commands
automatically set the value for TAP2.
Adjusting level correction between
sensor taps
The one-push command should be executed after setting
the output level to all black by removing light sources.
When One-push or Continuous is performed as taking
an image normally, the shade difference of an object is
detected as the level difference between taps and level
correction may not work properly on rare occasions. In
this case, the limit value (BL-AB-LIMIT) should be
adjusted so that the level is automatically adjusted to the
proper value. Lowering the value allows preventing
excessive detection but interferes the normal level
correction between taps to work properly. The level
should be adjusted accordingly since the optimal value
differs depending on the environment (such as an object
and light source) and camera settings (such as gain and
shutter).
Output Bit Depth
Monochrome cameras can switch between 8 bits, 10
bits, and 12 bits. Color cameras can switch between Raw
output 8 bits, 10 bits, 12 bits, and RGB output 24 bits.
Gain
Analog gain
The analog gain can be set finely in 1 dB unit or bit level
(up to 18 dB). It can be set per the sensor tap as well.
Digital gain
The digital gain is not implemented in this device.
Auto gain (AGC)
By executing the GAIN-AUTO command, the gain is
automatically adjusted according to the image pickup
environment. AGC works so that the average level in a
detection frame may reach AGC-LEVEL. The AGC
detection frame is set to the central region by default.
The detection frame can be displayed or the detection
area changed.
