Capturing Images
The image-capture process is an intuitive, split-second operation for experienced users. By following basic guidelines, however,
new users can easily develop their own technique and, with practice, quickly learn to adapt to different application environments.
Image Preview
When the imaging process is initiated, the screen displays a preview of the object. This is a live video image of what
the imager is currently viewing and has a slightly degraded appearance compared to the captured image. This slight
degradation is normal; the captured image has a higher resolution.
File Formats
The Dolphin terminal is capable of saving images in a number of industry-standard file formats such as *.bmp, *.jpg
and *.png. The default file format for images is a grayscale *.jpg. To obtain the highest quality images, take
grayscale images.
File Size
Digital images have a maximum image size of 640 x 480 pixels and an image definition up to a 256 grayscale. The
image quality and related file size are determined by the data compression method used by the software application
used to take the image. The average size of the image file is approximately 4–8K. However, the size of the image
depends on image content; the more complex the content, the larger the file size.
Taking an Image
1. Tap Start > Demos > Image Demo .
2. Point the Dolphin 7850 terminal at the object.
3. Press the scan trigger to activate the engine. The screen displays a preview of the object.
4. Adjust the terminal’s position until the preview on the screen appears as you want it to appear in the image.
5. Hold the terminal still and release the Scan trigger. The screen flashes and the captured image appears on the screen.
6. By default, the image is saved to the My Device folder ( Start > Programs > File Explorer > My Device ).
To save the image to another location, tap File > Save As .
High-Vis Aiming Pattern
If your Dolphin terminal is configured with an 5300 imager, you can enable the aiming pattern for imaging in the Image Demo
application. For details about the aiming pattern, see
Omni-Directional Scanning Positions on page 5-4.
1. Tap Start > Demos > Imaging Demo > Options menu > Aimer .
2. The aiming pattern is now enabled for imaging.
Uploading Images
Image files can be transmitted to a host workstation via
• Microsoft ActiveSync and a Dolphin communication peripheral, or
• Over your wireless radio network.
