An image correction method comprises the steps of: median-processing the original image in a direction normal to a direction in which the streak unevenness extends to produce a median-processed image, subtracting the median-processed image from the original image to produce a subtraction image, threshold-processing a part of the subtraction image having a density exceeding a given threshold to reduce the density and produce a threshold-processed image, frequency-processing the threshold-processed image using a one-dimensional low-pass filter in the direction in which the streak unevenness extends to produce a processing image, and subtracting the processing image from the original image to remove the streak unevenness from the original image.
An image correction method for removing a streak unevenness from an original image, the method comprising:
