PURPOSE:To enable correction calculation for the move velocity of a subject by calculating the jiggling quantity of a subject occurring with change of the image magnification to correct the image blur caused by jiggling, vibration or the like of a subject or photographic apparatus. CONSTITUTION:Focal distance information of a photographic lens 11 is outputted from a focal distance information output part within a mechanical blur detection part 25. From subject distance information and subject distance information from a subject distance detection part, a photographic magnification is calculated by a CPU 15. On the basis of a blur detection correction signal according to this photographic magnification and image blue detection information, information on the jiggling velocity is calculated by the CPU 15. Image deviation occurring with move of a focal point optical system 12 in blur detection is thus corrected, so that an accurate blur due to jiggling can be detected. |
