Lo will appear on the left-hand side of the Information display. Press the
shutter button to change to that resolution mode. Notice how the image
counter immediately changes. The number of (available) images will
increase (by almost four times) when you change from Hi to Lo.
Conversely, when changing from Lo to Hi, the image count will decrease by
approximately one-fourth.
4.9 Image Compression -
Image compression is a technique that allows digital images to be stored
efficiently in the cameras memory. The
camera has 8 MB of memory space.
Every image must be electronically compressed (squeezed) so that a
reasonable number of images may be stored in the available 8 MB memory.
If you compress your images more, you can store more images. However,
when images are compressed they loose quality. Too much compression
reduces the visual quality of your digital images.
The ViviCam 3350 has two compression settings. High compression,
(symbolized by “Hd”) results in highly compressed images. The camera
can store twice the number of images using Hd compression. Low
compression (symbolized by “Ld”) will offer better images.
To change the compression, turn-on the camera. Press the Menu button
seven times until Hd or Ld appears in the display. This is the current
compression setting. Press the shutter button to change to the other
compression. Try capturing images in both modes to decide which you
prefer. Notice, however, that it takes longer to capture an image using Hd
compression. The camera will be somewhat slower using Hd.
