    • A focus adjusting apparatus employable for an imaging system with an image-capturing unit configured to capture an image of an object, includes a unit configured to extract a specific frequency component from an image capturing signal along each horizontal scanning line to generate a focus signal and a unit configured to set a focus signal extraction area with reference to the image capturing signal. A peak holding unit extracts a line peak value by peak-holding the focus signal along each horizontal scanning line in the setting area. A first evaluation value generation unit generates an integral evaluation value by integrating line peak values obtained along a predetermined number of horizontal scanning lines of all the horizontal scanning lines in the setting area. A control unit performs a focus adjustment that includes driving a focus lens based on an AF evaluation value derived from the integral evaluation value.
