Number of lines to be read
By narrowing the image range to be loaded, the image
scan time can be shortened.
Set the range taking the offset of the measurement
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 processing item setting window or the Main
screen.
Note
About minimum number of lines
• The minimum number of lines (minimum number of lines between start and end lines) is 12 lines.2043
• For 5 megapixel cameras, the end line is fixed from 1921 to 2043.
About coordinate values
• The coordinate values displayed as the measurement results are the values of the display position on the monitor.
• The coordinate values do not vary according to the settings for "Number of lines to be read".

Important
• When the built-in lighting of an FZ-SQ is used, it may not be possible to shorten the processing time due to
restrictions on the light emission time.

Set value
Measurements are done in frame units.
Measurements are done in field units. Select "Field" when you prefer shorter
image input time rather than higher accuracy.
Processing becomes faster since each image is scanned skipping one scan
line per two consecutive lines, but the measurement precision is decreased
because the vertical image resolution is lower.
