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 terminal at the object.

3.Press the scan trigger to activate the engine. The screen displays a preview of the object.

4.Adjust the Dolphin terminal’s position until the preview on the screen appears as you want it to appear in the image.

5.Hold the Dolphin 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 on page 5-6.

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.
