Image processing apparatus, image recording apparatus, image processing method, and recording medium storing an image processing program

摘要

In an image processing apparatus, after a rasterizer checks resolution of raster data, if the resolution of the raster data is lower than a predefined resolution, a barcode detector analyzes the raster data and detects a barcode area. If there is a barcode area, a barcode direction determining unit determines barcode direction, and a resolution convertor enhances resolution of the barcode on black planes in a direction perpendicular to the bar direction of the barcode.

主权项

1. An image processing apparatus, comprising:
an acquisition unit to acquire image data; a detector to detect a barcode area in the acquired image data in case a first resolution of the image data is not higher than a set resolution and to detect a bar direction of a barcode in the detected barcode area; and a resolution converter to convert the first resolution of the image data in a direction perpendicular to the bar direction of the barcode into a second resolution higher than the first resolution.
