PROBLEM TO BE SOLVED: To provide an image processor and a computer readable storage medium capable of detecting a symbol part from an image in a short time.SOLUTION: An image processor in an embodiment includes: a division section; a calculation section; a determination section; and an output section. The division section divides an image into plural areas. Based on a piece of tone information of a pixel constituting the respective areas, the calculation section calculates a standard deviation and an entropy for each of the areas which are divided by the division section to calculate the ratio between the standard deviation and the entropy. The determination section determines an area the ratio of which exceeds a reference value. The output section outputs a piece of information based on a determination result by the determination section.SELECTED DRAWING: Figure 4 |
