PROBLEM TO BE SOLVED: To reduce problems caused by unintended change in the value of a pixel in an object.SOLUTION: A computer program makes a computer achieve an acquisition function for acquiring the original image data generated by reading a document optically, a correction function for generating the corrected image data by performing a specific correction processing for the original image data, an extraction function for extracting the contour of a first object in the original image by using the original image data, a generation function for generating the output image data representative of the output image by using the corrected image data, and an output function for outputting the output image data. The specific correction processing is a processing for changing the value of a pixel having a tone value in a specific range into a specific tone value. The output image includes a contour image indicating the contour of the first object, and an image indicating a second object in the corrected image different from the first object.SELECTED DRAWING: Figure 6 |
