<p>PURPOSE:To execute photographing in conditions corresponding to the actual photographing conditions by detecting a moving body when the detection of moving is not required, and detecting the camera moving when photographed image blurs by camera moving. CONSTITUTION:The focal length (f) of a lens is obtained by communication with a lens control circuit 2. The inverse of the focal length 1/f is compared with a Tv value (Tvp) for giving shutter speed and whether the photographing conditions at this time, are tend to blur or not, is decided. In other words, generally, the camera movement tend give ill effects to a photograph, because the photographing is executed at the shutter speed lower than 1/f. By this comparision, a photographing mode is selected depending on either the shutter speed is lower than a prescribed value 1/f or the shutter speed is higher than the prescribed value. When Tvp<1/f+1.5EV is obtained by the selection, a camera moving detecting mode is selected, and in the case except it (Tvp>=1/f+1.5EV), the moving body detecting mode is selected.</p> |
