[Camera N: Camera setting (3D Camera Image Input)]

The following items can be set in Camera setting.

Note

The displayed items differ depending on the camera type and lighting mode. Perform the following procedures as needed to suit the environment of your camera.
Camera/Lighting Combination and Available Functions

Camera settings

Adjust the settings related to camera shutter speed and camera gain.

Select the shutter speed appropriate for the speed of the measured object. Choose faster shutter speed if the measured object is moving fast and the image is blurred.

Where the specific shutter speed, iris, and lighting condition cannot be used to brighten the image, the camera gain should be adjusted. Usually, the factory default value can be used.

In the "Item tab" area, tap [Camera setting].
The Camera Setting window is displayed.

In the "Camera settings" area, specify the shutter speed.

Select "Select typical value", and tap [

] to set the shutter speed.

Table: Camera Setting (3D Camera Image Input) - Camera Condition Setting
Item	Set Value [Factory Default]	Description
Shutter speed	Options (example) [1/120] (For 2 Mega pixel cameras) 1/200 [1/500] (For 0.3 Mega pixel cameras) 1/1000 1/2000 1/4000 1/8000 1/20000	Option values for the shutter speed differ depending on the camera type.

Specifying a value directly:

Select "Set by number", tap [...] and specify a value.
For how to input value, see

User's Manual, "Inputting a Value"

In the "Camera settings" area, specify the camera gain.

While verifying the camera-input image, adjust "Gain" by dragging the slider in the "Camera settings" area.

Fine-tuning

Tap the buttons at both ends of the slider.

Specifying a value directly:

Tap [...] for "Gain" and input a value.

For how to input value, see

User's Manual, "Inputting a Value"

Table: Camera Setting (3D Camera Image Input) - Camera Settings
Item	Set Value [Factory Default]	Description
Gain	0 to 230 [50] (for camera with more than 640 by 480 pixels) [85] (for camera with 640 by 480 pixels or less)	Adjust the camera gain when specific shutter speed, iris, and lighting condition cannot be used to brighten the image. Usually, the factory default value can be used.

For the subsequent operations, see

Setting [3D Camera Image Input].

Frame/Field - for Monochrome Cameras Only

Select the unit to be treated as one image.

Note

For frames and fields, see About Frame Images and Field Images.

In the "Item tab" area, tap [Camera setting].
The Camera Setting window is displayed.

In the "Frame/field" area, select either [Frame] or [Field].

Table: Camera Setting (3D Camera Image Input) - Frame/Field
Item	Set Value [Factory Default]	Description
Frame/Field	[Frame]	Measurements are made in units of frames.
Frame/Field	Field	Measurements are made in units of fields. Select "Field" when you prefer shorter image input time rather than higher accuracy. Processing becomes faster since each image is scanned while skipping one scan line per two consecutive lines, but the measurement accuracy lowers since the vertical resolution of images lowers.

For the subsequent operations, see

Setting [3D Camera Image Input].

Number of Lines to be Read

By narrowing the image range to be scanned, the image scan time can be shortened.

Set the range taking the offset of the measured object into consideration.

The part of the image narrowed down by the start line and the end line will be displayed in the "Image display" area of the ProcItem Setting window or of the Main screen.

Description of Image Range to be Scanned

Note

About minimum lines

The minimum lines (the minimum number of lines between the start and end lines) are 12 lines.

About coordinate values

The coordinate values displayed as the measurement result are those values of the display position on the monitor.
The coordinate values do not vary with the settings for the "Number of lines to be read".

In the "Item tab" area, tap [Camera setting].
The Camera Setting window is displayed.

In the "Number of lines to be read" area, specify the start/end line.

When dragging the slider to change the start/end line

Drag the slider while verifying the image in the "Image display" area.

Camera Setting - Number of lines to be read Area

Specifying a value to change the start/end line:

In the "Number of lines to be read" area, tap [...] and input the coordinate values for the start/end line position.
For how to input value, see

User's Manual, "Inputting a Value"

The start and end lines are displayed in the "Image display" area.

Table: Camera Setting (3D Camera Image Input) - Partial Scan Settings
Item	Set Value [Factory Default]	Description
Start line	0 to Y_PMAX	Specify the scan start position.
End line	0 to [Y_PMAX]	Specify the scan end position.

For the subsequent operations, see

Setting [3D Camera Image Input].

Electronic Flash Setting

In the "Item tab" area, tap [Camera setting].
The Camera Setting window is displayed.

In the "Electronic flash setting" area, specify each item.

Camera Setting - Electronic Flash Setting Area

Tap [...] for "STEP-STGOUT delay" and "STGOUT width" and input a value for each.
For how to input value, see User's Manual, "Inputting a Value"

Select the STGOUT pulse polarity.

Table: Camera Setting (3D Camera Image Input) - Electronic Flash Setting
Item	Set Value [Factory Default]	Description
STEP-STGOUT delay	[0] to 511 (1 count 30μs)	Refer to the timing chart and set the Waiting Time from the time the STEP signal is input to the strobe trigger output signal becomes ON. Delay Time=Count x 30μs + 90μs
STGOUT width	1 to 63 [3] (1 count 30μs)	Specify the strobe trigger pulse width.
STGOUT polarity	[Positive] Negative	Select the strobe trigger pulse polarity. Positive: Flashes when strobe trigger output signal changes from OFF to ON. Negative: Flashes when strobe trigger output signal changes from ON to OFF.
