Abstract
There is provided a technology that enables reduction of an amount of data to be processed in testing a printed image printed on a printing medium. A printing apparatus includes a printing unit, a camera, and an image-data output unit. The printing unit is capable of printing plural categories of test patterns on the printing medium. The camera captures an image of a test pattern printed on the printing medium, and outputs acquired image data to the image-data output unit. The image-data output unit reduces an amount of data of the image data output from the camera, in accordance with the category of the test pattern, and outputs acquired image data to a test apparatus.
Claims8
A printing apparatus comprising:
- a printing unit configured to be capable of printing plural categories of test patterns on a printing medium;
- a camera configured to output image data acquired by image capture of the test patterns;
- and
- an image-data output unit configured to be capable of reducing an amount of data of the image data output from the camera, in accordance with each category of the test patterns, and outputting acquired image data,
- wherein the image-data output unit includes a bit reduction circuit configured to reduce the number of bits per pixel representing color depth or color gradation in the image data output from the camera, and
- wherein the bit reduction circuit reduces the number of bits per pixel in the image data output from the camera when one of the test patterns is a pattern for front/back verification or a pattern for registration adjustment.
