and High is image quality. The Normal Quality images are compressed more
than the High Quality images. As such, the Normal Quality images require
less image storage space per image, whereas the High Quality images will have
a better image quality.
• Lock/Unlock - Allows you to lock the currently displayed image so that it can
not be erased. You can unlock images that are currently locked.
Note: Using the Twain driver User Interface, you may make these same changes
with your mouse and keyboard, while the camera is connected to your PC.
Erasing Images from Memory
The Erase button (button 5) allows you to remove an unwanted image from memory.
You may erase images from either internal memory or from a CF card that is in
the camera. To remove images, the LCD image display must be on.
1. Turn on the camera, turn on the LCD display, then press the Play/Record
button and go to the Play mode.
2. To remove images individually, scroll to the picture then press the erase
button (button 5). A small dialog box will appear and ask you to confirm the
deletion. Press the Forward button (button 11) to acknowledge “Yes”, or the
Backward button (button 12) to decline (No). You will then be prompted to
delete the next image. When you are done erasing, exit to the LCD preview
screen by pressing the Backward button (No).
3. To erase all images in memory at once (as opposed to each, individually),
press the Menu button (button 6). When the Menu-options screen appears, advance
to the Erase-All icon, which is the second icon, in the top row. Press the
shutter button. You will be presented a small dialog box that asks you to
confirm your choice to delete all images. Select “+” to erase all, or “-” to
exit without erasing. Erasing all images will erase images from both internal
and CF card memory.
Note: Once your images have been erased, they are gone. Not even our customer
service or factory repair can retrieve them.
Defining Image Quality
The ViviCam 2750 can capture images in two different quality modes: Normal
(compressed) and High (less compressed). Both modes capture images at 640 x 480
resolution. With 2-MB internal memory, Normal Quality allows you to capture at
least 32 images, while High Quality allows you to capture at least 16 images.
Note the difference between resolution and image quality. In either mode the
resolution (pixel count) is 640x480 pixels. The difference between Normal and
High is image quality. The Normal Quality images are compressed more than the
High Quality images. As such, the Normal images require less image storage
space per image, whereas the fine images will have a higher image quality.
To select image quality:
1. Power on the camera, turn on the LCD, and press the Menu button (button 6) to
display the menu options in the LCD display.
2. Use the Forward button (button 11) to cycle through the options to the second
icon, in the bottom row, which is the Quality icon.
