Abstract
An image processing device includes: a memory that stores a program including a procedure; and a processor that executes the program, the procedure including: acquiring an image including a plurality of pixels, and changing luminance of the pixel that is included in either a high luminance part of a barcode region or a low luminance part the barcode region, the barcode region being set on the image, based on a luminance difference between the high luminance part and the low luminance part.
Claims16
An image processing device comprising:
- a memory;
- and
- a processor connected with the memory, to:
- acquire image data and barcode data indicating a barcode including a high luminance part and a low luminance part,
- set a region of the image data, the region including a plurality of pixels, and
- change, for each of the plurality of pixels, a luminance value into another luminance value based on a determination as to whether each of the plurality of pixels correspond to the high luminance part or the low luminance part of the barcode data, a comparison between the luminance value and a value corresponding with a moving average level of luminance values associated with the region, and a luminance difference needed to distinguish the high luminance part and the low luminance part.
An image processing method executed by a computer comprising:
- acquiring image data and barcode data indicating a barcode including a high luminance part and a low luminance part;
- setting a region of the image data, the region including a plurality of pixels;
- and
- changing, for each of the plurality of pixels, a luminance value into another luminance value based on a determination as to whether each of the plurality of pixels correspond to the high luminance part or the low luminance part of the barcode data, a comparison between the luminance value and a value corresponding with a moving average level of luminance values associated with the region, and a luminance difference needed to distinguish the high luminance part and the low luminance part.
A computer-readable recording medium storing an image processing program causing a computer to execute a process for processing images, the process comprising:
- acquiring image data and barcode data indicating a barcode including a high luminance part and a low luminance part;
- setting a region of the image data, the region including a plurality of pixels;
- and
- changing, for each of the plurality of pixels, a luminance value into another luminance value based on a determination as to whether each of the plurality of pixels correspond to the high luminance part or the low luminance part of the barcode data, a comparison between the luminance value and a value corresponding with a moving average level of luminance values associated with the region, and a luminance difference needed to distinguish the high luminance part and the low luminance part.
