PROBLEM TO BE SOLVED: To provide a slip image output device which can output a highly precise image for a whole slip and can improve the visibility of a user. SOLUTION: An image extraction part 40 extracts the image of a character filling area from the multilevel image of the detected slip, and a filter processing part 41 executes a filter processing for making the image of the character filling area into high precision. An image synthesis part 42 synthesizes the image of the character filling area after the filter processing and the image of a background which is not extracted by the image extraction part 40. A display part 5 displays the synthesized image as a visible image. The deterioration of the image of the background can be prevented by executing the filter processing only on the image of the character filling area, Then, the highly precise image can be obtained for the whole slip by synthesizing the image after the filter processing and the image of the background which is not filterprocessed. |
