An aperture compensation circuit which includes a first differentiating circuit for differentiating an input signal to its input terminal to provide a primary differentiated signal, a squaring circuit for squaring the primary differentiated signal to provide a first signal, a second differentiating circuit for differentiating the primary differentiated signal from the first differentiating circuit to provide a secondary differentiated signal as a second signal, and a dividing circuit for dividing the first signal by the second to provide a contour compensation signal which is not affected by the steepness degree of the input signal.
