Hand Held Products 4620, 2020 system manual Image Ship Imgshp

G - Gain: This modifier boosts the signal and multiplies the pixel value.

1G No gain (default)

2G Medium gain

4G Heavy gain

8G Maximum gain

D - Delta for Acceptance: This sets the allowable range for the white value setting (see W - Target White Value). Delta is only available when using Photo Style. (Default = 25)

nD Range: 0 - 255

L - LED State: Determines if the LEDs should be on or off, and when. Ambient illumination (0L) is preferred for taking pictures of color documents, such as ID cards, especially when the imager is in a stand. LED illumination (1L) is preferred when the imager is hand held. LED State is not available when using Decoding Style.

0L LEDs off (default)

1L LEDs on

T - Wait for Trigger: Waits for a hardware trigger pull before taking the image.

0T Takes image immediately (default)

1T Waits for a trigger pull, then takes the image

U - Update Tries: The maximum number of frames the imager should take to reach the Delta for Acceptance. Update Tries is only available when using Photo Style. (Default = 6)

nU Range: 0 - 10

W - Target White Value: Sets the target for the median grayscale value in the captured image. For capturing close-up images of high contrast documents, a lower setting, such as 75, is recommended. Higher settings result in longer exposure times and brighter images, but if the setting is too high, the image may be overexposed. Target White Value is only available when using Photo Style. (Default = 125)

nW Range: 0 - 255

%- Target Set Point Percentage: Sets the target point for the light and dark values in the captured image. A setting of 75% means 75% of the pixels are at or below the target white value, and 25% of the pixels are above the target white value. Altering this setting from the default is not recommended under normal circumstances. To alter grayscale values, Target White Value should be used. (Default = 50)

n% Range: 1 - 99

Image Ship - IMGSHP

An image is taken whenever the trigger of the IT4620 is pressed, or when the Image Snap (IMGSNP) command is processed. The last image is always stored in memory. You may “ship” the image by using the IMGSHP command.
