2Photographing Images

(1)Choosing display mode

Display mode here refers to one that is used to determine how an image is displayed on the screen. Choose your desired display mode from “1.3Mp,” “1.3Mi,” “5Mi” or “C.Scan.” Normally choose “1.3Mp.”

Feeling or features of camera operation vary with a combination of display mode and the source you use during photographing. Refer to “Outline Guide to Source (Photographing Mode) Settings” in “1.4.2 Image File Settings－File Settings” Chapter VI.

Sample settings that suit different uses are described below. Try these settings before determining your own settings.

•Fine-adjusting the focus for a subject consisting of minute patterns → 1.3Mp or 5Mi

Ex.:

Semiconductor pattern, low-magnification photography of cells and tissue,

 

fluorescent photography, landscape photography with a lens

•Moving the subject while observing → 1.3Mp

Ex.:

Semiconductor pattern, stereoscopic microscope observation, cell diagnosis,

 

general photography with a lens

•Focusing on a dark subject → 1.3Mi

Ex.:

Position or focus adjustment during fluorescent photography, nighttime

 

photography with a lens

•Photographing a dark subject in the shortest time possible → 1.3Mi

Ex.:

Fluorescent photography, nighttime photography with a lens

•Photographing a bright subject with priority placed on focusing → C.Scan

Features of display modes

The following describes features of each display mode.

5Mi: Observation with high-definition images

An image consisting of 5.07 million pixels is compressed for display at a rate of 3.75 frames per second.

•Misregistration of colors may occur for moving subjects.

•Effective for observing a subject that specifically requires delicate focusing as when photographing fine patterns or lines.

•Effective for long exposure periods because shutter delays are nonexistent.

1.3Mp: Photographing or observing a moving subject

An image consisting of 1.3 million pixels is displayed at a rate of 7.5 frames per second.

•Misregistration of colors does not occur even if the subject moved while being photographed.

•Effective for cases where as when photographing a high-contrast subject whose dark and bright parts are clearly distinguishable, you are concerned about misregistration of colors caused by a movement of the microscope stage.

•A moving subject can be photographed while being made to pause with a high-speed shutter.

•You can set a combination of display modes, e.g., “1.3Mp” for observation and “5Mi” for photography. Use File Settings of the SETUP menu to make such a setting. Refer to “1.4.2 Image File Settings－File Settings” in Chapter VI.
