Usage Precautions
Be sure to always observe the following precautions.
1. Never use general-purpose image retouching software to edit or overwrite the images files for the CR-DGi Image
Viewer. The study information and image information written into the image file can be corrupted or become
unreadable.
2. Do not use the preview screen in Windows XP to rotate an image file for the CR-DGi Image Viewer. If an image is
rotated, the study information and image information written into the image file can be corrupted or become
unreadable.
3. If the display is not set to full color, the colors may not be displayed properly. To set the display colors in Microsoft
Windows, select Display Properties, go to Settings, and then check that the Colors is set to True Color (24 bit or
32 bit).
4. Use the CR-DGi Image Viewer in a system environment with the proper security protection. The CR-DGi Image
Viewer itself does not have any security protection functions.
5. In CR-DGi Image Viewer, the study information and image information are saved to the image in clear text.
6. Be sure to always test beforehand to check that images are captured and saved properly.
7. The user of the CR-DGi Image Viewer needs to belong to the member of the Power Users group or the
Administrators group.
IMPORTANT
Original images captured by the CR-DGi are reversed horizontally and vertically and do not have an
aperture mask.
Be sure to always use the CR-DGi Image Viewer to rotate the image 180 degrees and add an aperture
mask to the image.

1. Introduction
1.1 Overview
This software package is a viewer application specifically for the Canon Non-Mydriatic Retinal Camera CR-DGi
(called “CR-DGi” below). Retinal images captured from the EOS digital camera installed on the CR-DGi are
automatically loaded, and special CR-DGi image processing is performed to display the images. If necessary, the
study information is recorded together with the image and saved to a folder created for each capture date.
Images captured using the CR-DGi are automatically received and displayed.
Exif and RAW images can be captured.
Any size image set by the EOS digital camera can be captured.
Images can be saved in JPEG, BMP, and RAW formats.
Study information is saved inside the JPEG file.
Images can be magnified and reduced in size, and the brightness and contrast can be adjusted.
Images can be printed with the study information.
Images can be managed using dated folders.
Images can be managed by the counter number for each date.
Images can be compared.

1.3 Image Management of the CR-DGi Image Viewer
Images recorded by the CR-DGi Image Viewer are rotated 180 degrees, combined with an aperture mask, and then
displayed on the monitor. When an image is saved, image information and study information are added to the
appended information of the JPEG image, and the image is saved to a folder with the capture date. Under the
standard settings, only JPEG images are saved, but it is also possible to save uncompressed image formats such as
BMP and original images captured by the retinal camera in formats set by the digital camera.
