What Factors Affect The Resolution Of Kiosk Barcode Scanner?

There are various brands of kiosk barcode scanners on the market, and the prices of each brand are also different, and there is also a certain gap in quality. So do you know what are the factors that affect the resolution of the QR Code Scanner? Today, let's learn about it with the editor of Honor Way electronics.

Factors Affecting OEM 2D Barcode Scanner Resolution

The resolution of the Ticket Barcode Reader should be determined from three aspects: optical part, hardware part and software part. That is to say, the resolution of the Kiosk Barcode Scanner is equal to the resolution of its optical components plus the resolution obtained by its own processing and analysis through hardware and software.

Optical resolution is the actual number of light spots that can be captured per square inch by the optical components of the Megapixel Barcode Scanner. It refers to the physical resolution of the scanner CCD (or other optoelectronic devices), and is also the true resolution of the barcode scanner. The value is the value obtained by dividing the pixels that can be captured by the photoelectric element by the maximum horizontal scan size of the qr code scanner. For example, a Barcode Scanner Module with a resolution of 1200DPI usually only has a resolution of 400600DPI in the optical part. The resolution of the extended part is generated by the combination of hardware and software. This process is generated by analyzing the image through the computer and mathematically filling the blank part (this process is also called interpolation).

Optical scanning and output are one-to-one. The output content is the same as the scanned content. After being processed by computer software and hardware, the output image will become more realistic and the resolution will be higher. Most of the Bluetooth Barcode Scanner on the market have software and hardware expansion functions for resolution. Some Bluetooth Barcode Scanners are marked with 96009600DPI, which is only the maximum resolution obtained by software interpolation, not the true optical resolution of the barcode scanners. So for the Bluetooth Barcode Scanner, its resolution has optical resolution (or optical resolution) and maximum resolution. Of course, what we care about is the optical resolution, which is the strength of the scanners.

We say that the resolution of a Imaging Barcode Scanner Module is as high as 4800DPI (this 4800DPI is the sum of optical resolution and software difference processing), which means that when the scanner is used to input images, on a 1 square inch scanning width, 4800 4800 pixels (Pixel). 1-inch square scanning area, the image size generated after scanning with 4800DPI resolution is 4800Pixel4800Pixel. When scanning images, the higher the scan resolution, the finer the resulting image and the larger the resulting image file, but with more interpolation components.

The above editor of Honor Way electronics introduces the factors that affect the resolution of scanners, hoping to help you when purchasing Kiosk Barcode Scanner.
