Chromatic Aberration Correction; Connecting Rotary Encoders - JAI SW-4000T-10GE User Manual

Chromatic Aberration Correction

This Function corrects for the chromatic aberration of magnification caused by the lens (i.e.,
when the size of the image differs at the focal point for each color (RGB)). You can save
correction data for three types of lenses. This function assumes that the amount of deviation
between the left and right is identical. If the amount of deviation between the left and right is
not identical, correction will not be performed properly. Specify the number of pixels to delay
or advance the R channel and B channel using the G channel as a reference. The correction
range is –4.0 to +4.0 in steps of 0.1.
■ Adjustment procedure
1
Enable the chromatic aberration of magnification correction function.
Set [Chromatic Aberration Correction Mode] to [On].
Alternatively, select preset Lens1, Lens2, or Lens3.
2
Correct the R channel.
Set [Chromatic Aberration Correction Selector] to [RChannel].
Specify the amount of correction in [Chromatic Aberration Correction Lens1,2,3]
(–4.0 to +4.0 in steps of 0.1).
3
Similarly, correct the B channel.
Set [Chromatic Aberration Correction Selector] to [B Channel].
Specify the amount of correction in [Chromatic Aberration Correction Lens1,2,3]
(–4.0 to +4.0 in steps of 0.1).

Connecting Rotary Encoders

This camera can generate trigger signals or detect the scanning direction of the subject in
response to signals output from the rotary encoder.
■ Adjustment procedure
1
Input the two signals (phase A and phase B) from the rotary encoder.
Select which I/O on the camera (Line5:OptIn1, Line4:TTLIn1, Line10:TTLIn2,
Line13:TTLIn3) you want to input each of the two outputs from the rotary encoder
[phase A (Encoder Source A), phase B (Encoder Source B)].
2
Specify the number of triggers (number of vertical lines) to generate during
each rotation of the rotary encoder.
When [Encoder Divider] is set to [N], the rotary encoder generates 65536/N triggers.
When N is an integer multiple of 65536
Camera internal trigger is generated by decimation of output trigger of rotary
encoder.
When N is not an integer multiple of 65536
Using the time interval of the output trigger of the rotary encoder, Camera internal
trigger is generated so that the set division ratio is obtained.
Note
If the time interval of the output of the rotary encoder fluctuates greatly, the output
of the camera internal trigger generated may also fluctuate greatly.
In this case, by setting [EncoderAveragingInterval], it is possible to perform internal
processing with the value obtained by averaging the time intervals of the specified
number of signals.
