PROBLEM TO BE SOLVED: To strike a balance between speed improvement for fill-in-the-blank processing in a character part and image quality improvement at the same time.SOLUTION: An image processing apparatus generates a quantized region by integrating regions included in an input-multivalued image and have similar colors, determines an attribute of a connected component included in the generated quantized region, determines a color for filling a connected component determined to have a character attribute, and executes processing for filling the connected component determined to have the character attribute. When fill-in-the-blank processing in the character part is performed, the image processing apparatus changes a method for determining the color for filling based on the quantized region adjacent to the connected component determined to have the character attribute. |
