Abstract: An image capture apparatus includes a high frequency signal extraction unit, a first filter unit, a second filter unit and a level setting unit. The high frequency signal extraction unit extracts a high frequency signal from an input signal. The first filter unit applies a horizontal band-pass filter to the input signal. The second filter unit applies a vertical band-pass filter to the input signal. The level setting unit sets a level, which is used to remove a noise component from the high frequency signal, to one of a first level and a second level lower than the first level. The level is set to the first level, if the input signal is obtained from a first area including low contrast. The level is set to the second level, if the input signal is obtained from a second area including small pattern.
