Abstract

PURPOSE: To detect the image blur during exposure by arranging an image blur detecting area sensor in such position that it does not intercept the object light during exposure.
CONSTITUTION: At the time exposure, the luminous flux passing a lens group forms the image of an object on a film 5. An image blur detecting optical system 9 forms the object image, which is formed on the film 5, on the light reception face of an image blur detecting sensor 8 again. The sensor 8 converts the luminance distribution of the object image on the film 5, which passes the image blur detecting optical system 9, to an electric signal and outputs this signal to an image blur operation device 10. The image blur detecting optical system 9 and the sensor 8 are arranged in the bottom of a mirror box so that they do not intercept the object light at the time of exposure. The image blur operation device 10 calculates the extent of shake of the image based on the change of the output of the sensor 8.
