The color is poor.
• Set the white balance.
=> See “2 Photographing Images” in Chapter VI.
• Apply a moderate amount of color compensation.
=> See “2 Photographing Images” in Chapter VI.
• Turn off hue adjustment.
=> See “2 Photographing Images” in Chapter VI.
• Set the color temperature of the internal monitor and external monitor
to an appropriate level.
=> See “1.4.4 Adjusting Monitor Output for an External Monitor” in
Chapter VI.
• Set the color temperature of the illumination to an appropriate level.
The contrast is low.
• Set the tone appropriately.
=> See “2 Photographing Images” in Chapter VI.
• Avoid adjusting the black level to the positive side of SFT.
=> See “2 Photographing Images” in Chapter VI.
• Adjust the size of the field diaphragm so that it circumscribes the
viewfield.
• Adjust the size of the aperture diaphragm to approximately 70% to
80% of the numerical aperture of the objective.
=> See “Chapter V Microscope Adjustment.”
• Use an appropriate filter.
When using a phase contrast microscope or an interference
microscope (two luminous fluxes or multiple luminous fluxes), insert
the specified filter. With a black and white image, contrast is improved
by inserting a green interference filter (GIF). Contrast in color images
is enhanced by inserting a filter having a complementary color to that
of the specimen.
=> See “Chapter V Microscope Adjustment.”
• Adjust the ambient light around the microscope.
Make the room darker, or place caps on the binocular eyepiece, for
example.
• Check the contrast of the specimen itself.
Noise appears at the
edges of the menu
when shown on an
LCD monitor or
projector.
• Adjust the clock phase of the LCD monitor or projector.
