6.3 Image Parameters Setting
1. Select "Continuous shooting", check "Image Setting".
2.Adjust "
照明强度
", "Exposure Time" and "Gain" to view the image changes in real time,
as shown in the example. When the illumination intensity is set to 0, the image is dark,
When the illumination intensity is set to 2, the image is obviously brighter and the sample
barcode is displayed in a green frame, which can be successfully decoded;
3. Adjust the "exposure time" to view the image changes in real time, the image
brightness will also change significantly, the image contrast will change significantly. For
static barcode reading applications, the "exposure time" has little effect on the reading
success rate; if the mobile reading application "exposure time" has a greater impact on
the reading success rate, the exposure time parameters can be calculated according to
the barcode size and other parameters;
4. Adjust the "Gain", check the image changes in real time, the image brightness will also
change significantly and the image contrast will change significantly;
5. For special barcode reading applications, the filtering algorithm needs to be adjusted.
Lighting intensity is set to 0
Lighting intensity is set to 2
