Capturing Images
The image-capture process is an intuitive, split-second operation for experienced users. By following the basic guidelines, new
users can easily develop their own technique and, with practice, quickly learn to adapt it to different application environments.
Image Preview
When the imaging process is initiated, the Dolphin 7900 touch 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 is normal.
File Formats
The 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 may have up to a 256 grayscale image definition. The image
quality and related file size are determined by the data compression method used by the software application used to take
images. The average size of the image file is approximately 4-8K. However, the size of the image depends on the content of the
image - the more complex the content, the larger the file size.
Taking an Image
1. Tap Start > Demos > Imaging Demo.
2. Point the Dolphin 7900 terminal at the object.
3. Activate the engine. The touch screen displays a preview of the object.
4. Adjust the terminal’s position until the object appears on the screen the way you want it to appear in the image.
5. Hold the terminal still and release the SCAN key or side button. The touch 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
You can enable the red, high-vis aiming pattern for imaging in the Image Demo application.
Tap Start > Demos > Imaging Demo > Options menu > Aimer. The aiming pattern is now enabled for imaging.
