Image processing device, method for processing image, and program for processing image
Abstract:
An image processing device is comprising: an input unit which inputs image data of a chart; and a streak detection processing unit which specifies an inspection region in the inputted image data, calculates a line average which is an average of all pixels on a line, for each line in a sub-scanning direction in the inspection region, calculates a width average value which is an average of the line averages of the lines corresponding to a series of main scanning pixels, the number of which is a specified width and whose center is a target pixel, for each target pixel, calculates a difference between the width average value, and the average of the line averages of the target pixel and a predetermined number of main scanning pixels, and determines that the target pixel is included in a streak when the difference exceeds the threshold value set in advance.
