Image forming apparatus |
摘要 |
An image forming apparatus, including: a reading portion configured to read an original to generate original image data; a code detecting portion configured to detect a code indicating image density reduction information from the original image data; a reconstruction processing portion configured to generate output image data from the original image data by using density input-output characteristics corresponding to the image density reduction information; a filter portion configured to perform unsharpness processing on the output image data by using a degree corresponding to the image density reduction information; and an image forming portion configured to form an image based on the output image data subjected to the unsharpness processing. |
