HV-D30 Microscope Setup
The HV-D30 uses a menu system to make changes to the operation and settings of the camera.
MENU Button – Pressing this button turns on or off the
camera on screen menu system.
UP Button – This button moves the cursor in the UP
direction.
RIGHT Button – This button moves the cursor to the
RIGHT.
LEFT Button – This button moves the cursor to the
LEFT.
DOWN Button – This button moves the cursor in the
DOWN direction.
Pressing and holding the UP button while pressing and holding the MENU button for 2 seconds puts
the camera in the SPECIAL SET MENU.
In order to get the best performance from the Hitachi HV-D30 when it is used on a microscope, the following settings are recommended.
Activate the MENU system by pressing the MENU button on the rear of the camera. Using the
DOWN arrow key scroll down to the bottom of the screen and make sure that the FILE SELECT is set
to File 1, (any File number can be used except PRESET) Use the RIGHT arrow key to change the
FILE setting. All camera settings made will be saved to the selected FILE and will be retained even
when the camera is powered down. Changes made to the PRESET FILE will not be saved when the
power is removed from the camera.
•
Using the UP arrow key scroll to the top of the menu and set the CAMERA MODE to MANUAL by using the RIGHT arrow key. Scroll down to the WHITE BALANCE mode and
change this setting to AUTO or MEMORY depending on the application. See explanation of
these choices at the end of this page.
•
Turn off the MENU by pressing the MENU button. Next we need to enter the SPECIAL SET
MENU. Hold down the UP arrow and press and hold the MENU button for 2 seconds. The
screen will display the SPECIAL SET MENU. Use the DOWN arrow key to scroll down to the
LENS setting. Change the LENS type to DC. Use the LEFT arrow key to go back to the SPECIAL SET MENU.

•
The output signal from the D15-HD connector is factory set to R,G,B. If you need to
change this to some other signal, use the DOWN arrow key to scroll down to the OUTPUT /
SYNC setting. Use the RIGHT arrow key to select the type of output you desire from the
D15-HD connector (R,G,B / Y-C / Y, R-Y, B-Y). Exit the SPECIAL SET MENU by pressing the MENU key.
•
Return to the main MENU by pressing the MENU key. Scroll down to the AGC setting by
using the DOWN arrow key. Set the AGC to ON by using the RIGHT arrow key. Use the
left arrow key to return to the main settings.
•
Scroll down to the GAIN setting and change the GAIN to 12 db by using the RIGHT arrow
key. Use the left arrow key to return to the main settings.
•
Scroll down to the SUB MENU 1 setting and select this choice by use of the RIGHT arrow
key. Use the DOWN arrow key to go to the SHUTTER setting. Change the SHUTTER
setting to AES using the RIGHT arrow key. Use the left arrow key to return to the main
settings.
•
Scroll down to the AES LIMIT setting and change the setting to 1/ 124144. Use the left
arrow key to return to the main settings.
•
Scroll to the top of the MENU using the UP arrow key and then use the LEFT arrow key to
return to the MAIN menu.
•
Scroll down to the SUB MENU 2 setting and select this choice by use of the RIGHT arrow
key. Scroll down to the DYNA CHROMA setting using the DOWN arrow key and select
this choice by use of the RIGHT arrow key. Change the setting from OFF to ON. Use the
left arrow key to return to the main settings. Scroll to the top of the MENU using the UP
arrow key and then use the LEFT arrow key to return to the MAIN menu.
The changes made will allow the settings to be stored in memory when the camera is powered down,
and will allow the camera to operate over a wide range of light levels through the use of the AGC and
AES settings.
White Balance: The ability of the camera to adjust to a particular color temperature of light, and make
a white object appear white on the monitor is the function of the white balance circuit in the camera.
There are several methods that are commonly used to accomplish white balance.
Most modern color television cameras have three basic modes of white balance. For proper operation,
and to obtain the correct results, it is important to know when to use a particular mode.
Preset White Balance: In this mode, the camera is balanced for white, under light that normally has a color temperature of 3200 degrees Kelvin. This is the typical factory adjustment when the camera is set for white balance, and corresponds to the light normally used
in TV studios. Operation of the camera under light that is the same color temperature, as
that used in the factory, will produce proper color balance, and good color rendition.

Memory White Balance: In this mode of operation, the camera is pointed at a white object,
and the auto white button is pressed. The camera then automatically adjusts the red and
blue gains to produce white. This method is normally used for white balance, due to the
fact, that it also takes into account any effect the color temperature of the light may have on
the object being shot. Depending on the camera, this mode of operation has a large range of
color balance, and can handle light with color temperatures from approximately 2000 to
5800 degrees Kelvin.
Auto Tracking White: In this mode of operation, the camera attempts to make the brightest
object in the picture white. The red and blue gain are constantly and automatically adjusted
by the camera to account for differences in the color temperature of the light. This mode is
useful for long shots, and when the camera must shoot between different color temperatures
of light, without being white balanced. There is a drawback to this mode, in that it will attempt to make the brightest object in the scene white. Should the scene not contain any
white object, but rather a light colored object, the camera will make this white. This will
cause all of the color reproduction of the camera to be incorrect.
For microscope applications, it is recommended that the memory mode of white balance be used. The
camera should be white balanced under the illumination level that will be used for the slide. The slide
should be removed, leaving a pure path of light to the camera. The camera would then be white balanced, by pressing the auto white button. The slide can then be inserted in the path, and the colors
should then be correct. If the light intensity is changed, the camera may need to be white balanced
again, because normally the color temperature of the light will change with its intensity.
