Abstract
A method of operating a barcode scanner includes: capturing an image by an image capturing device, the image including a barcode, and the image capturing device having a first focal length, wherein the image capturing device is configured to auto-focus on the image; adjusting the first focal length of the image capturing device to a second focal length different from the first focal length; scanning the barcode in the image; and fixing the second focal length until a time interval is exceeded.

A method of operating a barcode scanner, comprising:
- capturing an image by an image capturing device, the image comprising a barcode, and the image capturing device having a first focal length, wherein the image capturing device is configured to auto-focus on the image;
- adjusting the first focal length of the image capturing device to a second focal length different from the first focal length;
- scanning the barcode in the image;
- and
- fixing the second focal length until a time interval is exceeded.
A method of operating a barcode scanner, comprising:
- capturing an image by an image capturing device, the image comprising a barcode, and the image capturing device having a first focal length;
- adjusting the first focal length of the image capturing device to a second focal length different from the first focal length;
- scanning the barcode in the image;
- fixing the second focal length until a time interval is exceeded;
- and
- displaying a countdown dynamic message on a user interface of the barcode scanner, and the countdown dynamic message being displayed with the time interval.
A barcode scanner, comprising:
- an image capturing device configured to capture an image;
- a scanning module configured to scan a plurality of barcodes in the image;
- a focusing device configured to adjust the image capturing device to have a first focal length and a second focal length different from the first focal length;
- a timer module configured to set a time interval after the scanning module scans one of the plurality of barcodes;
- and
- a processor electrically or communicatively connected to the image capturing device, the scanning module, the focusing device, and the timer module, and the processor being configured to:
- control the focusing device to adjust the first focal length of the image capturing device to the second focal length;
- control the scanning module to scan the one of the plurality of barcodes as the image capturing device has the second focal length;
- and
- control the focusing device to fix the second focal length until the time interval is exceeded after the scanning module scans the one of the plurality of barcodes.
