CV-L107CL
29
Settings:
2100 to 2150400, in 25ns increments (19 kHz to 18 Hz)
Associated functions:
Trigger origin, TG=0
Applicable modes:
No-Shutter with Internal line rate generator
(TR=0)
Shutter-Select with Internal line rate generator
(TR=1)
Important note
The data can be stored in the camera memory for next start up.
8.19 Command NOSR – Noise reduction
This function deletes the noise component of less than 16LSB composed in the signal.
This circuit used in the CV-L107CL minimizes the deterioration of the spatial frequency.
The improvement depends on the object and it will be approx. 3dB.
Settings
0=ON, 1=OFF
8.20 Command PBC – Enable pixel black (FPN) correction
This command enables (or disables) the “pixel black level” correction function, which
compensates for Dark Signal Non Uniformity / Fixed Pattern Noise (DSNU / FPN) for
individual pixels.
Settings:
0 = Off
1 = Factory setting
2 = user area
Associated functions:
Command PBR
Applicable modes:
All
8.21 Command PBR – Run pixel black correction and store to user area
This command initiates the “pixel black level” correction function, and stores the settings
in the user area. When this function is activated, lens must be capped.
Settings:
0 = Run this function
Associated functions:
Command PBC must be set to 2
Important note:
This function requires that no light reaches the image sensors. The lens must therefore
be covered by a lens cap, or put the F-mount protective cover on the camera, when
executing this function.
As the black level is influenced by the exposure time (especially for long exposure time,
at slow scan rates) it is recommended to perform the pixel black correction at the
exposure time and line rate at which the camera will be operated.
8.22 Command PER – Programmable exposure – Red
This command allows individual setting of the exposure time of the Red channel. It is only
valid for the Shutter-Select mode (see chapter 6.6)
Settings:
2 to 2,150,400 in 25ns steps
Associated functions:
EI (R and G exposure interlocked with G)
The actual Exposure time (ns) is calculated as follows:
T
exp
= 25ns x T1(clk)
The conditions is to satisfy the following relation.
Repetition period (clk)
≧
T1(clk) + 30 clk
