Capturing Images; Image Preview - Dolphin 9500 Manual

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 9500/9550 displays a preview of the image on the touch screen. This is a live
video image of what the imager is currently viewing. This enables you to improve your aim and verify the image before you take it.
The live video preview has a slightly degraded appearance compared to the captured image. This is normal.
The Scan key
The Scan key captures images on both the Dolphin 9500 and the Dolphin 9550 terminals. It is the only way to capture an image
on the 9500, while on the 9550, you can also use the scan trigger on the pistol-grip handle.
Image quality and file size
The image quality and related file size are determined by the data compression method used by your software application. When
first captured, the image is saved in the JPEG file format. The average size will be approximately 4-8K. However, the size of each
JPEG depends on the content of each image–the more complex the content, the larger the file size.
For the highest quality (and often the smallest file size), take grayscale images.
To capture images on the Dolphin 9500
Complete these basic steps:
1 To aim, point the display end of the Dolphin 9500 straight on the target.
2 Press the SCAN key to preview the image. A live video image appears on the terminal screen. Use it as a guide while you
position and aim the terminal. You may find it helpful to start by moving the terminal away from and then closer to the target.
3 When the desired image is displayed on the terminal screen, release the SCAN key to capture the image.
For best results hold the Dolphin terminal as still as possible when you release the SCAN key.

while you position and aim the terminal. You may find it helpful to start by moving the terminal away from and then closer to
the target.
3 When the desired image is displayed on the terminal screen, release the Scan Trigger to capture the image.
For best results hold the Dolphin terminal as still as possible when you release the SCAN key.
