ABSTRACT:
An object of the present invention is to accurately perform focusing adjustment so as to take a picture that is free of an image blur. A prohibition CCPU is provided for prohibiting a change operation of an image blur correction coefficient change means ICPU and a light amount adjustment operation of light amount adjustment means SNS, SDR, and STR from being performed at the same time. Thus, an operation for selectively changing an image blur correction coefficient stored in storage corresponding to movement of a zooming optical member and (or) a focusing adjustment optical member disposed in a focusing optical system is not performed while a photoelectric converting device or a photosensitive material disposed in the vicinity of a focusing plane of the focusing optical system is being performed.
In addition, since the image blur correction coefficient is continuously changed, an image blur error is prevented even if the coefficient is changed.
