power supply.
PoE constant lighting ·······It always lights with PoE control lighting.
Emission time
When CAMERA_IN is selected in the trigger setting and PoE pulse lighting is
selected in the lighting control, set the emission time from when the trigger is input to
the lighting power supply.
Multishot
When CAMERA_IN is selected in the trigger setting, set the number of images to
capture for each trigger. When set to multiple images, the imaging interval is the
value of FrameRate.However, if the exposure time is longer than FrameRate, the
exposure time value is applied.
Timeout time
When TRIG or CAMERA_IN is selected in the trigger setting, you can set the timeout
time with the camera. If there is no input within the set time, an error occurs.
Brightness
Adjust the light intensity in 256 steps.
Light angle
When using split type ring lighting, it is used in combination with lighting directivity.
Adjusting this parameter allows you to set the intensity of ring lighting depending on
the angle. Adjust within the range of an angle of 0°to 360°.
Directivity
When using split type ring lighting, it is used in combination with lighting angle. When
the setting is 0, all lights are turned on. When the setting is 1, the light intensity at the
angle set by the light angle becomes the maximum, and the opposite side becomes
zero.
Calibration Setting
In order to improve the accuracy of dimension measurement,you can correct the dis-
tortion of the lens and the inclination of the imaging surface and the image sensor of
the camera.
Please contact the distributor if you need it.
<<Point>>
By executing the calibration, more reliable measurement can be carried out with the
measurement tool etc. Please be aware that error occurrence can not be avoided
due to various conditions, so it will not be guaranteed accuracy.
Unit correction value (mm/pix)
When unit conversion is selected for each tool, unit conversion can be done by set-
ting the length per pixel. The unit converted value is limited to 0.5 um resolution at the
minimum.
Correct
Unit correction value can be set by using measurement result with measurement tool.
With the measurement tool enabled, measuring the distance between the two points,
entering the actual length into the span input and executing the correction value cal-
culation will calculate the unit correction value.
If you enter the camera setting mode with the distance measurement tool enabled,
you can take over the measurement result of the measurement tool.
Adjust white balance
When using a color camera, color tint may be misaligned due to temporal change of
the color tone of white lighting and RGB sensitivity difference of each camera. In
order to correct this, place a plain work and perform white balance adjustment.
In that case, please make each RGB brightness value about 100 ~ 150. If the bright-
ness value is too low or too high, it will not run properly.
When placing the mouse cursor on the image, the luminance value is indicated by (R,
G, B) together with the position (X, Y) as shown below(Except during continuous exe-
