ReadRateFirstSettings Sample
The Read-Rate-First Settings Sample illustrates how to maximize the rate when using Dynamsoft Barcode Reader Android SDK. Generally, the Read Rate of a barcode reader refers to the rate of successfully recognized barcode among all barcodes in the given image in one scan.

Regular Settings
The Region Definition
It is not recommended to make configurations on the scan region if the app is focusing on improving the Read-Rate. Dynamsoft Barcode Reader Android SDK will scan the full image by default.
The Format Specification
The barcode formats can be specified via PublicRuntimeSetting. The default value of DBR is not supporting all available barcode formats. Optimizing the barcode format settings to cover the requirements will help you to create a high-efficiency and high-read-rate barcode reader that covers your usage scenario.

The Barcode Count
The barcode count setting determines the maximum barcodes the barcode reader can recognize at once from a single image/frame. Increasing the expected barcode count benefits the read rate but declines the reading speed at the same time.
Modes Parameter Settings
Suppose the barcode format and the barcode count are completely set. The main factors that determine the read rate are how to localize as many barcodes as possible and how to recognize all the localized barcodes.
Localization Friendly Parameters
The following pre-processing modes parameter settings will benefit the localization process. The barcode reader always tries different parameter combinations to find as many barcodes as the pre-set value. Despite the influence on processing speed, pre-set more parameters will definitely improve the read rate of your barcode reader.

|---|---|
ColourConversionModes |
Convert the coloured image into grayscale image. |
