Black inverted noises in a white background due to resolution correction are reduced by an image processing apparatus which carries out image modification processing to invert at least a portion of a binary converted signal obtained from binary conversion of an image signal. An image signal S,is respectively input to resolution correction means,and,using different correction amounts. The signal is then input to selecting means,from the both resolution correction means. The signal output from the selecting means is input to binary conversion means,and a signal S,output therefrom is input to image modification processing means,. when image modification processing has been instructed, a control signal CNT,is input to the selecting means,and the selecting means output a signal with weak resolution correction from the resolution correction means,using a small correction amount.
