Image processing apparatus, image processing method, and program for converting an m-value into an n-value image |
摘要 |
An apparatus capable of dividing an m-value image into a plurality of divided images and performing quantization into an n-value image (2@n<m) for each divided image includes a first quantization unit for quantizing a first region in the divided image similarly to a region to be joined, and a second quantization unit for sequentially quantizing a second region in the divided image including the first region. If the second quantization unit quantizes the first region, parameters for the quantization processing is corrected using a quantization result in the first quantization unit such that the quantization result approaches the quantization result in the first quantization unit. |
