PROBLEM TO BE SOLVED: To provide an image processor, an image processing method, and a program capable of producing a high quality binarization image with a relatively small amount of computation.SOLUTION: An image processor includes a binarization unit 21 for generating corrected image data by filtering a reading multi-level image the sample area of which is set by a sample area setting unit 20, and then binarizing the corrected image data, a correlation operation unit 22 for determining the correlation of binarization image data and reading multi-level image data, and an optimum binarization information selection unit 23 for selecting optimization information by correlation. The binarization unit 21 includes a parameter value setting unit 212 for setting a plurality of parameter values by adding a variable addition amount to the coefficients of a target pixel in a filter, and a filtering unit 211 for generating corrected image data corresponding to the parameter values, by forming a matrix including a target pixel in the center and surrounding pixels, and filtering the reading multi-level image data by using a filter for which the parameter values are set. |
