Abstract
Various embodiments herein each include at least one of systems, methods, devices, barcode scanners, and software for variable depth of field scanning devices and methods. One such embodiment includes determining a distance from a known point to an item presented for scanning by a barcode scanner. This embodiment further includes adjusting a variable lens of a camera of the barcode scanner to a depth of field based on the determined distance.
Claims20
A method comprising:
- adjusting a variable lens of a camera to a first depth of field;
- capturing a number of first images with the camera at the first depth of field;
- outputting at least one of the number of the first images to a barcode reading process;
- adjusting the variable lens of the camera to a second depth of field;
- capturing a number of second images with the camera at the second depth of field;
- outputting at least one of the number of the second images to a barcode reading process;
- adjusting the variable lens of the camera to a third depth of field;
- capturing a number of third images with the camera at the third depth of field;
- outputting at least one of the number of the third images to a barcode reading process;
- and
- restarting the method.

A method comprising:
- determining a distance from a known point to an item presented for scanning by a barcode scanner;
- and
- adjusting a variable lens of a camera of the barcode scanner to a depth of field based on the determined distance.
A barcode scanner comprising:
- at least one camera, each camera having a variable lens;
- a processor;
- a memory device;
- a barcode reading process stored in the memory that is executable by the processor;
- instructions stored on the memory device that are executable by the processor to independently perform data processing activities with regard to each of the at least one cameras to adjust respective variable lenses thereof, the data processing activities comprising:
- adjusting a variable lens of a camera to a first depth of field;
- capturing a number of first images with the camera at the first depth of field;
- outputting at least one of the number of the first images to the barcode reading process;
- adjusting the variable lens of the camera to a second depth of field;
- capturing a number of second images with the camera at the second depth of field;
- outputting at least one of the number of the second images to the barcode reading process;
- adjusting the variable lens of the camera to a third depth of field;
- capturing a number of third images with the camera at the third depth of field;
- outputting at least one of the number of the third images to the barcode reading process;
- and
- restarting the data processing activities with regard to the respective camera.
