Camera Mode

Select the camera mode. For "Hi-res" mode and "Hi-spd" mode, one measurement is performed for each
image.
For "HDR" mode and "NR" mode, two images are taken by the camera for each trigger, and then one
measurement is performed for these two images.
Tips
• After the camera mode is changed, measurements are not performed for the first two triggers.
Camera mode: "Hi-res"
z z
All pixels will be used by the camera to take a high resolution image. Normally use this mode.
Camera mode: "Hi-spd"
z z
Pixels will be averaged in sets of four. Image capture time will be 1/4 but resolution will be half in both
the horizontal and vertical directions.

Camera mode: "HDR"
z z
In "HDR" (High Dynamic Range) mode, screens captured by the camera at two different shutter speeds
are combined. This makes it possible to perform stable measurements of parts that are highly reflective
or that are minimally reflective.
Use this mode when you cannot capture images with a single shutter speed such as for metallic
surfaces on circuit boards, very uneven surfaces, or when the surface exhibits large color or profile
differences.
Tips
• Because two images are taken for each measurement, this mode has a long sampling period.
• When measuring workpieces that move at a high speed, the HDR image combination may not be
perform appropriately.
