Operation of the camera mode
1. Workpieces where HDR
is effective
Use this mode when measuring workpieces that have parts whose reflective
status vary greatly. The following example uses a workpiece that has a
white and a black part, as shown in the figure to the right.
To measure this workpiece, it is necessary to acquire a profile like that
shown below.

2. Problems with the “Hi-res”
camera mode
In “Hi-res” mode, if the shutter speed is increased (made shorter),
the reflected light from the black part is insufficient to perform the meas-
urement. If the shutter speed is decreased (made longer), the reflected
light from the white part is saturated, leading to poor precision.
