IMAGE READING APPARATUS AND IMAGE FORMING APPARATUS |
摘要 |
An image reading apparatus includes a color line sensor that converts an image of an original document into an electric signal at first resolution and a monochrome line sensor that converts the image of the original document into an electric signal at second resolution higher than the first resolution. The image reading apparatus further includes an image-quality improving circuit that calculates a correlation between first image data obtained by reading the image of the original document at the first resolution with the color line sensor and second image data obtained by reading the image of the original document at the second resolution with the monochrome line sensor and converts the first image data into third image data having resolution higher than the first resolution on the basis of the calculated correlation.
