-# How to Read Barcodes from Large Images
-
-In some cases, the captured image is very large, so Dynamsoft Barcode Reader (DBR) may require more memory and take longer to read the barcode. To speed up the barcode localization process and reduce memory overhead, you can configure the `ScaleDownThreshold` parameter to shrink the image size. If the shorter side length of the image is larger than `ScaleDownThreshold`, the library will shrink the image (50% on each dimension) until the shorter side is less than the threshold.
-
->Note:
->
->Don't worry about the location of the barcodes, as DBR will still return their coordinates in the original image.
-
-## Example
-
-Below is an example illustrating how to configure the parameter `ScaleDownThreshold`.
-
-* Update parameter `ScaleDownThreshold` in your JSON template
-
- ```json
- {
- "CaptureVisionTemplates": [
- {
- "Name": "CV_0",
- "ImageROIProcessingNameArray": ["TA_0" ]
- }
- ],
- "TargetROIDefOptions" : [
- {
- "Name": "TA_0",
- "TaskSettingNameArray": [ "BR_0" ]
- }
- ],
- "BarcodeReaderTaskSettingOptions": [
- {
- "Name" : "BR_0",
- "SectionImageParameterArray": [
- {
- "Section": "ST_REGION_PREDETECTION",
- "ImageParameterName": "IP_0"
- },
- {
- "Section": "ST_BARCODE_LOCALIZATION",
- "ImageParameterName": "IP_0"
- },
- {
- "Section": "ST_BARCODE_DECODING",
- "ImageParameterName": "IP_0"
- }
- ]
- }
- ],
- "ImageParameterOptions": [
- {
- "Name": "IP_0",
- "ScaleDownThreshold": 1600
- }
- ]
- }
- ```
-
-* Apply the above settings following the article [Use Templates for Configuring Parameters]({{ site.features }}use-runtimesettings-or-templates.html#json-template).

->Note:
->
->1. If the image size is large and the barcode [`module size`](read-barcodes-with-small-module-size.md) is small, shrinking the image size may result in unreadable barcodes.
->2. Don't worry about the location of the barcodes, as DBR will still return their coordinates in the original image.
->3. For the JavaScript edition, a `BarcodeScanner` instance comes with a default `ScaleDownThreshold` of `2300`, which makes it easier to handle continuous video frames.

-# How to Read Barcodes with Imbalanced Colour
-
-As we all know, any color is composed of red, blue and green (RGB). If the image is a colour image, Dynamsoft Barcode Reader (DBR) will convert it to grayscale first for further processing.
-
-```math
-Gray = Red*RedChannelWeight + Green*GreenChannelWeight + Blue*BlueChannelWeight
-```
-
-The default weights in DBR are suitable for most cases. However, some color images may produce poor grayscale images based on the default weights. For example, the image below is a color image with imbalanced colour.
