Abstract
There is provided a printing apparatus including: an ink jet head that prints on a print medium; a camera that captures an image on the print medium; an LED light source that irradiates a capturing area of the camera with light at a predetermined angle with respect to a print surface of the print medium; a carriage that mounts the ink jet head, the camera, and the LED light source; and a processor that executes calculation based on captured-image-data-of-unprinted-area obtained by capturing an image on the print medium by the camera and captured-image-data-of-test-pattern obtained by capturing an image of a test pattern by the camera, the test pattern being printed on the print medium by the ink jet head, and that acquires corrected captured-image-data representing a captured image of the test pattern, the corrected captured-image-data in which an influence of light irradiation by the LED light source is adjusted.
