Image processing with conversion from N-value to M-value data |
摘要 |
An image processing method is disclosed in which a pattern for detecting a line image is compared with the value of image data within a predetermined window of the original image. N-value data is transformed to M-value data based on the result of this comparison. An image can thus be satisfactorily M-value coded without being adversely affected by noise.
