Abstract
An image processing unit detects an edge portion of an input image and outputs first data for correcting the detected edge portion. The image processing unit also detects a thin line in the input image and outputs second data for correcting the detected thin line. In a case where a pixel of interest is subjected to both correction processes using the first data and the second data, a greater correction amount is selected and the correction is made using the selected correction amount, and a result corrected image is output as an output image.
