IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, RECORDING MEDIUM, AND IMAGE FORMING APPARATUS |
摘要 |
An image processing device includes a first gradation processor to apply first pseudo halftone processing to image data, an edge detector to detect an edge portion of the image data to output a detection result, a correction value calculator to calculate an edge correction amount and convert the image data to corrected image data based on the edge correction amount, a second gradation processor to apply, to the corrected image data, second pseudo halftone processing for edge processing, and an output selector to adopt a processing result at the first gradation processor to a non-edge portion of the image data, and a processing result at the second gradation processor to an edge portion of the image data, based on the detection result at the edge detector. |

1. An image processing device, comprising:
a first gradation processor to apply first pseudo halftone processing to image data; an edge detector to detect an edge portion of the image data to output a detection result; a correction value calculator to calculate an edge correction amount and convert the image data to corrected image data based on the edge correction amount; a second gradation processor to apply, to the corrected image data, second pseudo halftone processing for edge processing; and an output selector to adopt a processing result at the first gradation processor to a non-edge portion of the image data, and a processing result at the second gradation processor to an edge portion of the image data, based on the detection result at the edge detector. |
