PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of appropriately extracting a character from image data regardless of a manner of trimming.SOLUTION: In an image processing apparatus, when a significant difference exists between a character pixel number in a gradation having the largest character pixel number and a character pixel number in a gradation having the second largest character pixel number, a character candidate element which is obtained after removing non-character element in a gradation having the largest pixel number is selected as an output image, and when a significant difference does not exist between a character pixel number in a gradation having the largest character pixel number and a character pixel number in a gradation having the second largest character pixel number, a character candidate element which is obtained after removing non-character element in a gradation having the smallest edge pixel number is selected as an output image. |
