IMAGE READING APPARATUS, IMAGE FORMING APPARATUS, AND NON-TRANSITORY COMPUTER READABLE MEDIUM |
摘要 |
An image reading apparatus includes an image reading section and a detection section. The image reading section includes at least two detection units, and performs a reading operation on an image. The at least two detection units have respective spectral characteristics which are different from each other. The detection section detects a condition of an irregularity on an image carrier by comparing a detection result of the image read by the image reading section with an output characteristic. The output characteristic is stored in advance and is a color component obtained from a value obtained by the image reading section reading a test image having a region in at least one color. |

1. An image reading apparatus comprising:
an image reading section that includes at least two detection units and that performs a reading operation on an image, the at least two detection units having respective spectral characteristics which are different from each other; and a detection section that detects a condition of an irregularity on an image carrier by comparing a detection result of the image read by the image reading section with an output characteristic, the output characteristic being stored in advance and being a color component obtained from a value obtained by the image reading section reading a test image having a region in at least one color. |
