<p>PURPOSE:To enable image blur detection even in a nonfocusing state or during lens driving by comparing relative deviation information with relative deviation information for image blur detection and detecting a real image blur. CONSTITUTION:A relative deviation information detecting means 9a detects the relative deviation information for image blur detection between a subject image signal generated by one of the photodetection parts of photoelectric converting means 3a and 3b and a last subject image signal stored in a 1st storage means B. Then an image blur detecting means 9b detect relative devia tion information between a couple of subject image signals due to the movement of a photographic optical system 1 driven by a driving means 7 according to a relative deviation quantity for focus detection which is found by a focus detection arithmetic means 5a and a last relative deviation quantity for focus detection which is stored in a 2nd storage means D and this relative deviation information is compared with relative deviation information for image blur detection detected by a relative deviation information detecting means 9 to detect the real image blur. Consequently, the image blur is detected even in the nonfocusing state or during the driving of the photographic lens.</p> |
