An information processing apparatus operates to acquire first information concerning a size of a print region where a barcode is printed, to generate, based on the acquired first information, image data of the barcode to be printed in the print region, and to set a lower limit of the width of each bar forming the barcode. The first information includes width information concerning a width of the print region and height information concerning a height of the print region. The generated image data includes, as a bar forming the barcode, a bar having a width based on the width information and a height based on the height information, and the image data is generated if a minimum width of each bar forming the barcode is equal to or larger than the set lower limit.

A microcontroller-based code reader and method of reading a machine-readable indicia may include capturing, by an imager, an image of a machine-readable indicia disposed an object. An image subsample of an image captured by the imager may be read from the imager. The image subsample or partial image data may be stored in an embedded memory of a microcontroller in electrical communication with the imager. The machine-readable indicia may be decoded from the image subsample.

Example methods and apparatus to read barcodes on reflective surfaces are disclosed herein. An example method for handling a reflective surface in an imaging reader includes capturing one or more images of a surface of an item; detecting whether a specular reflection is present in the one or more images; when a specular reflection is detected, processing one or more additional images of the surface using a predetermined pattern of first processing suitable to identify a barcode on a reflective surface and second processing suitable to identify a barcode on a non-reflective surface; and when a specular reflection is not detected, processing one or more additional images of the surface using the second processing suitable to identify a barcode on a non-reflective surface.

A camera-based barcode reader captures an image, determines a region of interest of a barcode within the image, and generates a barcode image from the region of interest. The camera-based barcode reader aligns each of multiple horizontal regions within the barcode image to a reference horizontal region within the barcode image. The alignment of a horizontal region includes (i) determining a set of alignment parameters to apply to the horizontal region based on a comparison of the reference horizontal region to the horizontal region when adjusted to different combinations of alignment parameters and (ii) adjusting the horizontal region according to the set of alignment parameters for that horizontal region. After aligning the barcode image, the camera-based barcode reader decodes the barcode from the barcode image.
