ELECTRONIC CAMERA THAT ADJUSTS A DISTANCE FROM AN OPTICAL LENS TO AN IMAGING SURFACE SO AS TO SEARCH THE FOCAL POINT

An electronic camera includes an image sensor having an imaging surface for capturing an object scene through a focus lens. When the object scene captured by the imaging surface includes a face portion of a human, a CPU designates, as a focal-point search area a first imaging area for covering an outline of the face portion. The CPU also designates, as a frequency-component detection area, a second imaging area that is smaller than the first imaging area and is for capturing an inner side of the outline of the face portion. Subsequently, the CPU obtains a high-frequency AF evaluation value and a mid-frequency AF evaluation value detected corresponding to the frequency-component detection area, and designates, as a lens moving range, a range different depending upon a relative ratio between the high-frequency AF evaluation value and the mid-frequency AF evaluation value. Thereafter, the CPU moves the focus lens within a designated range, and references a partial image generated on the imaging surface in a manner to correspond to the focal-point search area so as to search a focal point for the face portion.
