Imager Settings

Imager Settings#

Images and Video#

Imager Preferences#

This section serves as the general entry point for imager parameters related to decoding, image capture, video viewfinder, and image quality.

Work Mode#

Used for parameters related to the imager work mode, capture mode, or image output mode.

Mobile screen display mode#

Used to improve decode compatibility when reading from display media such as mobile phone screens and electronic displays.

Disable, default value
Enable

Video Resolution#

Used to reduce the resolution before video transmission, in exchange for smaller video data size by deleting rows and columns.

Option	Value	Video size
`Full Resolution`	`00h`	`752 x 480`
`1/2 Resolution`	`01h`	`376 x 240`
`1/4 Resolution`	`03h`	`188 x 120`, default value

Frame rate#

Used to control the frame rate during image acquisition and video transmission. Lower frame rates often help brighten images.

The following options are currently confirmed from the original text:

Auto, default value
60 fps
55 fps
50 fps
45 fps
40 fps
30 fps
20 fps
15 fps
10 fps

Note

When the frame rate is lower than or equal to 30 fps, the aiming pattern may appear to flicker.

Image File Size Selector#

Confirmed for use with JPEG Size Selector, which controls the maximum JPEG file size by entering a 3-digit value.

Image file metadata#

Controls whether JPEG images are accompanied by EXIF 2.2 metadata.

Enable Image File Meta Data
Disable Image File Meta Data, default value

When enabled, the following fields can be written to:

Time after power on
Sensor type
Device name
manufacturer
Frame rate
Host type
Image number after power on
Image enhancement parameters
Image sharpening parameters
Image contrast enhancement parameters

This setting has no effect on the TIFF and BMP formats.

video viewfinder#

Used to control whether the live video viewfinder is displayed in image mode.

Disable Video View Finder, default value
Enable Video View Finder

Video viewfinder image size#

Used to set the video viewfinder image size, the input unit is 100-byte block.

Value range: 800 to 12,000 bytes
Default: 1700 bytes

The smaller the value, the higher the frame rate; the larger the value, the higher the image quality.

Target video frame size#

Used to set the video data block size transmitted per second, the input unit is 100-byte block.

Value range: 800 to 20,000 bytes
Default: 2200 bytes

The smaller the value, the higher the frame rate; the larger the value, the higher the image quality.

Lighting and aiming#

Illumination#

This section explains the lighting control items in decoding and capture scenarios.

LED lighting#

Used to describe how an LED light source is enabled, disabled, or working. If you access a separate parameter page later, you can add the relationship between switch value and brightness in this section.

Image acquisition lighting#

Used to control whether lighting is enabled when taking a snapshot.

Enable Image Capture Illumination, default value
Disable Image Capture Illumination

Enabling lighting usually results in a better image, but the further away the target is, the less effective the fill light will be.

Lighting brightness#

Used to set lighting brightness by adjusting LED power.

Value range: 1 to 10
Default value: 10
Setting method: first scan the setting code below, then scan the 2-digit barcode to enter the brightness value

For example, when setting the brightness to 6, you need to scan the “Lighting Brightness” setting code first, and then enter 0 and 6.

Aim for brightness#

Used to set the aiming pattern brightness. The default value is 0, which means the aiming pattern continues to light up between two exposures; when the value is greater than 0``time, every increase1, aiming duration increased0.5 ms`.

Value range: 0 to 255
Recommended range: When the frame rate is 60 fps, it is recommended to use 0 to 30
Setting method: first scan the corresponding setting code, then enter the 3-digit barcode

Decode aiming pattern#

Used to control whether to project the aiming pattern during decoding.

Enable Decode Aiming Pattern, default value
Disable Decode Aiming Pattern

Enable decoded aiming patterns — * Enable decoding aiming patterns#

Note

If Picklist mode is enabled, the aiming pattern will still flash even if Decode Aiming Pattern is turned off.

snapshot aiming pattern#

Used to control whether to display the aiming pattern in snapshot mode.

Enable Snapshot Aiming Pattern, default value
Disable Snapshot Aiming Pattern

Snapshot mode timeout#

Used to set the time the device stays in snapshot mode. After a timeout or triggering event, the device exits snapshot mode.

The default value 0 means 30 seconds
For each subsequent increase of 1, the time increases by 30 seconds.

exposure and brightness#

automatic exposure#

Used to control whether automatic exposure and automatic gain are enabled in decoding mode.

Enable Decoding Autoexposure, default value
Disable Decoding Autoexposure

Enable decoded auto-exposure — * Enable decoding auto-exposure#

When turned off, gain and exposure time need to be set manually. Officially only recommended for use by advanced users in complex reading scenarios.

Note

Switching this parameter under Presentation Mode is not recommended.

Image acquisition automatic exposure#

Used to control whether automatic exposure and automatic gain are enabled in snapshot capture mode.

Enable Image Capture Autoexposure, default value
Disable Image Capture Autoexposure

* Enable automatic exposure for image acquisition#

Disable automatic exposure for image acquisition#

fixed gain#

Used to manually enlarge the original image data after decoding or image acquisition auto-exposure is turned off. Increasing gain increases brightness and contrast and may also increase image noise.

Default value: 50
Value range: 1 to 100
Input method: After scanning the setup code below, scan the 3-digit barcode

Exposure time#

Used to manually specify the exposure duration after turning off automatic exposure. The default value is 100, which is 10 ms. This parameter is more suitable for use with automatic exposure off scenes.

Each integer value represents 100 us
Default value: 100
Value range: 1 to 1000
Input method: After scanning the setup code below, scan the 4-digit barcode
