ISO Speed Setting
Default: 100
}Select the sensitivity (ISO speed) in image capturing. The figures are set
based on the ISO speeds of photo films.
Three options of 100, 200 and 400 are available. The larger ISO speed
is more suitable for recording of dark specimens or quickly-moving
objects.
The larger ISO speeds are suitable for recording of dark specimens, but they also increase the image noise.
Select the optimum setting according to situations.

Sharpness Setting
Default: NORMAL
}Select the image sharpness. The sharpness refers to the degree of
contour enhancement of image.
Three options of “NORMAL,” “SOFT” and “OFF” are available.
The contour enhancement attenuates as the setting is changed from
“NORMAL” to “SOFT” and then to “OFF.”
“NORMAL” sharpens the image contours and is suitable for appreciation of prints, etc. “SOFT” reproduces contours in a
natural feeling. “OFF” does not apply sharpness correction and is therefore suitable for subjecting to post image process-
ing on a PC, etc. Select the optimum setting according to situations.
