3.2 Capturing an Image (Image View)

In Image View, there are two methods of capturing a Grayscale

VGA image with the ISC-Imager.

Image Mode is optimized to capture images at

short range. While in Image View, pressing the

trigger or tapping the camera icon on the menu bar

turns on the green aiming LEDs. A text prompt is

displayed notifying the user to trigger again to start capture.

The aiming LEDs remain on until a second trigger/icon tap or

until six (6) seconds elapse, whichever comes first. If a second

trigger is received within six seconds, the imager captures an

image and sends it to the host in the currently selected size and

format. The image appears on the host screen, rotated 90°

counterclockwise.

To save the image, tap Tools | Save Image As.

Preview Image Mode is best used for longer

distance image capture where a preview allows

better framing of the subject. However, this mode

takes longer to preview and capture the image. When this icon

is tapped, the imager continuously captures and displays

213x160 pixel images on the display until the user taps this soft

button a second time.

The application then retrieves the next captured image using

the current size and compression settings (See section on

Image Transfer on Page 10) and displays it on the host screen.

The images captured by the imager have an aspect ratio of 4:3

while the display of most (if not all) Pocket PC PDA/PDT’s is

3:4. The application default (Normal View) is to display the

captured image rotated counterclockwise 90° so that the

maximum amount of the image is displayed. The user may

choose to display the image right side up. However, when

Upright View is enabled, the image received will also be

cropped to fit the display, and the left and right edges of the

image are lost.

Note: After using Preview Mode to capture an image, the ISC-Imager automatically switches to Camera

Mode. Tap the Preview Mode icon to capture another image.
