Troubleshooting
Clear Images Cannot be Obtained
Measurement sometimes cannot be performed successfully (e.g. measurement image is dark or contrast is
low) depending on the characteristics of the measurement target. Sharp images can be obtained by applying
filtering, or performing correction and adjustment to remedy the trouble.
Measurement Target Cannot be Measured Accurately
Due to Movement
When the measurement target is moving (e.g. its position or orientation are not fixed), it moves out of the
preset measurement region, which prevents accurate measurement. The ZFX-C is provided with a "position
shift correction function" that corrects the position shift of measurement regions such as this before performing
measurement. The position shift correction function enables measurement targets whose position or
orientation is not fixed to be measured accurately.
Position Correction p.113
Trouble Remedy Reference
Poor lighting The recipe method light control settings can be used. You can set the lighting
just by selecting the image that meets your specific requirements from the
thumbnails of images automatically taken under different lighting patterns.
p.106
Low contrast You can apply filters, such as "Sharpen", to the image to enhance the bound-
aries between shadow and highlight areas.
p.101
Uneven image • You can apply filters, such as "Smooth", to the image to smooth out
unevenness in the image.
• White parts of the image can be corrected to be reproduced appropriately
by adjusting the white balance.
p.101, p.136
Dark image You can raise the camera's sensitivity or lengthen the shutter time to make the
image brighter.

moves out of position
The position of the measurement
target is measured after the mea-
surement region is shifted by the
amount of position shift.
