PURPOSE:To prevent the saturation of the capacity of a ROM, etc., by correcting a de-focusing quantity by using the variable data by means of the 1st means of a de-focusing quantity correcting means in accordance with the discriminated result of a discriminating means or the variable data by means of the 2nd means and fixed data. CONSTITUTION:Variable data for correcting a de-focusing quantity and fixed data to be used for updating the variable data are stored in a correcting quantity storing means. The de-focusing quantity against an object obtained by means of an optical means, photoreceptor means, and focus detecting means is corrected by a de-focusing quantity correcting means by means of the correction (1st means) using is variable data of the storing means or the correction (2nd means) using the variable data and fixed data of the storing means in accordance with the discriminated result of a discriminating means and a lens driving means drives an interchangeable lens on the basis of the corrected de-focusing quantity. Therefore, the de-focusing quantity can be corrected effectively without saturating the capacity of a ROM 64, etc., with the data. |
