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.

Image size: This selects the pixel size of JPEG files. The Original setting saves that image at the same size as
the captured image. The 3072, 2160, and 1440 settings indicate the pixel width, and the aspect
ratio of the image is not changed. The default setting is Original.
Date order: This sets the format of the date folder.
Save option: Although the image is saved as a JPEG file under the standard settings, when a checkmark is
inserted in this option, the BMP file and the original file before image adjustment are saved at
the same time. BMP files are saved as BXXXX.bmp, and original files are saved as
RXXXX.crw(jpg). The “XXXX” portion is the same number as the JPEG file.
Limit for displaying message: A warning will be displayed when the storage capacity of the disk where Save
folder is stored becomes lower than the value set here. The default setting is 500(MB).
Item1: This defines the “Note1” label in the Study Information. Up to 12 bytes of alphanumeric characters can

4. Other Operations
4.1 Loading from a CF Card
Recorded images may be stored in the CF card loaded in the digital camera without being transferred to the PC
if images are recorded without connecting the digital camera to the CR-DGi Image Viewer or if some type of
error terminates the software while the image is being recorded. This section shows the procedure for later
loading the retinal images saved to the CF card to the CR-DGi Image Viewer.
1.
7.
Set the main switch of the digital camera to OFF, and check that the access lamp is turned off. Open the
CF card slot cover, and then press the Eject button to unload the CF card.
Insert the card into a CF card reader connected to the PC.
The PC recognizes the CF card as a removable disk.
Open Explorer, and display the list of images in the CF card.
Start the CR-DGi Image Viewer, select the Capture tab, and then switch to Capture mode.
From Explorer, drag each retinal image in the order that it was captured to the thumbnail window or main
window of the CR-DGi Image Viewer. If you drag more than one image at a time, the images will not be
ordered according to their capture time.
Enter the Study Information and Image Information if necessary.
8.
Click the

button to save. The images are put into the saved date folder.
When ejecting the CF card from the CF card reader, open My Computer, and then right-click the icon for the
CF card reader, and click Eject from the pop-up menu. Then, take the CF card out of the slot.
24
4.2 Backup and External Storage of Image Files
Back up the image folders under the save folder on a regular basis. Possible methods of backing up are shown
below.

 Use Explorer to copy the folders to another hard disk.

 Copy the save folder to CD-R, DVD, or other removable media.

 Use the backup tools in Windows 2000/XP.

 Use a commercial backup utility.
When the amount of available space on the hard disk containing the save folder and capture folder becomes
less than 500 MB, an alert is displayed when starting the software and when saving an image. In this case, you
should immediately free space on your hard disk. Possible methods of freeing disk space are shown below.

 Move old date folders that are not viewed in Explorer to another hard disk.

