An image emphasizing apparatus includes: an outline component extraction section; a threshold value calculation section for calculating first and second threshold values; and an outline correction section for generating an outline emphasizing signal from the outline component based on the first and second threshold values, and adding the outline emphasizing signal to the input video signal, thereby generating an output video signal, wherein the outline correction section includes: an emphasizing signal generation section for generating the outline emphasizing signal, which is generated while limiting an absolute value of the outline component so as to be equal to or smaller than the first threshold value when the absolute value of the outline component is equal to or smaller than the second threshold value; and a signal addition section for adding the outline compensation signal generated based on the outline emphasizing signal to the input video signal.
