Image processing apparatus and method using dot patterns |
摘要 |
The present invention relates to an image processing method and an image processing apparatus, and an object thereof is to improve resolution and also suppress indention of contour, thereby improving image quality. In order to achieve the object in a case where multi-gradation image data is quantized to be converted into quantized pixel patterns, a smoothing portion of a quantized image is detected and a contour of the quantized image is corrected by interpolating pixels of the detected smoothing portion the quantized pixel pattern of the smoothing portion in the detected quantized image is replaced by a pixel pattern for smoothing stored in a memory.
