Tilted View Correction and Chromatic Aberration Correction
This camera features a tilted view correction function.
The G channel, B channel, and R channel are positioned in that order on the sensor used on
this camera.
The G channel and R channel are corrected using the B channel in the middle as a reference.
The user can adjust the amount of correction to capture the best possible image based on the
angle of the camera in relation to the subject, the distance between the camera and the
subject, the lens used, and other factors.
The tilted view correction function also 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
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).
2
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).
3
Enable the chromatic aberration of magnification correction function.
Set [Chromatic Aberration Correction Mode] to [On].
Alternatively, select preset Lens1, Lens2, or Lens3.
Spatial Compensation Function
This function corrects the spatial pixel differences individually for the R, G, and B lines
captured by the trilinear line sensor.
Two modes are available; Manual and Auto.
Configuring settings for SpatialCompensationMode: Manual
You can configure the number of pixels to correct individually for the R, G, and B lines.To do
so, configure the SpatialCompensationR, SpatialCompensationG, and SpatialCompensationB
values.
Configuring settings for SpatialCompensationMode: Auto
In this mode, the number of pixels to correct individually for the R, G, and B lines is calculated
automatically using the trigger interval at which the camera operates, the amount of
movement in pixels of the imaging subject within the sensor during a single trigger
(SpatialCompensationDistance), and the movement direction (Object Direction) signal of the
subject.
The object direction signal is used to obtain the direction of the imaging subject. The direction
signal from the rotary encoder, the I/O signal input of the camera, or the high/low control
signal from the software can be used as the object direction signal.
