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.

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.

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.
