<P>PROBLEM TO BE SOLVED: To suppress a focus detection error caused by the aberration of a photographing lens. <P>SOLUTION: The focus detecting device includes: a microlens array where a plurality of microlenses are two-dimensionally arrayed; a light receiving element array having a plurality of light receiving elements for every microlens, and configured to receive luminous flux from an imaging optical system through the microlenses; and a focus detection calculating means for calculating the focusing state of the imaging optical system on the basis of the output of the light receiving signal of the light receiving element array. The array of the microlenses is varied in accordance with the position on the microlens array. <P>COPYRIGHT: (C)2008,JPO&INPIT |
