An apparatus and method of processing shoot artifacts of an image signal includes a maximum gradient value calculation part to set a window of a predetermined size based on a current pixel of an input image signal and to calculate a maximum gradient value based on values of pixels in the window, a limit value calculation part to calculate a limit value corresponding to the maximum gradient value, a dilation amount calculation part to calculate a dilation amount corresponding to the current pixel based on the calculated limit value and a pixel difference between the current pixel neighboring pixels of the current pixel, and a pixel value conversion part to add a current pixel value to a value obtained by multiplying the calculated dilation amount by a predetermined gain value.
