摘要：
A blur detecting device for a camera comprises a CCD line sensor which is arranged in a position optically equivalent to the surface of the film to produce image signals at different points of time set in response to pushing a shutter button; and a signal processing circuit which computes the degree of a blur which occurred in the image between the different points of time by obtaining the degree of correlation between the image signals.
