Image Capturing
Gryphon D432/D412Plus can also function as a camera by capturing images of labels,
signatures, and other items.
In order to capture an image, the user should read a Capture Image code (see page 80), then
point at the image subject and pull the trigger. This way, the image will be captured and sent to
the host PC. Gryphon D432/D412Plus then returns to normal operation. To capture another
image you must read another Capture Image Code of the same or a different Preset
Configuration.
You can use the aiming system to position the reader from the object (ensure the reader is about
centered over the target). Adjust the distance at which you are holding the reader (see Figure 4
on page 13).
If the RS-232 interface has been selected, the image will be transferred to the host PC via
XMODEM_1K protocol.
Image capturing is not available in Wedge and USB Keyboard Emulation interfaces and is not compatible with Autoscanning
nor when the Software trigger type is selected.
Up to four different and independent Image Presets can be defined (see page 81).
Basic Configuration Parameters
The Image file formats supported are: TIFF
The resolution available is 752 x 480 pixels.
For JPEG images it is possible to define the Image Quality level to address tradeoff between
image file size and quality.
Advanced Configuration Parameters
By default, for all Image Presets, the window has its original coordinates equal to zero, its width
equal to 752 pixels and its height to 480 pixels.
Brightness Adjustment is available in the range from –100% up to 100%, in steps of 1%.
Positive values shift the luminance up so that the image will result brighter. Default value is 0%,
meaning that no brightness adjustment is performed.
The same range of values (–100% up to 100%, in steps of 1%) is available for Contrast
Adjustment. Positive values will increase the contrast, so that dark and bright objects inside the
image will be better distinguishable. Default value is 0%, which means that no contrast
adjustment is performed.
You can set the Image Color Depth by selecting 256 gray levels (default), 16 gray levels, or 2
gray levels. Higher color depths yield larger image files. This option is ignored if the JPEG
format is selected, (256 gray levels only).
