Title:
CAMERA PROVIDED WITH IMAGE BLURRING CORRECTING FUNCTION
Document Type and Number:
Japanese Patent JP3401337
Kind Code:
B2
Abstract:
PURPOSE: To provide a camera with an image blurring correcting function capable of judging whether or not a blurring correction is required without operating a means using an angular velocity sensor, etc., and used only for detecting the blurring.
CONSTITUTION: Whether the absolute value of a difference between the last photometric value Am and the present photometric value An in an area A measured by a photometric sensor is equal to or exceeding a prescribed reference value LVL is judged (S25). When the absolute value is equal to or exceeding the reference value, it is judged that the blurring correction is required, then, a flag H is set to '1' (S26), on the other hand, when the value is below the reference value, the flag H is set to zero (S28). During the exposure, the blurring quantity is repeatedly detected and calculated and a correction lens is also repeatedly driven until the exposure time is ended in the case the flag H is set be '1'. When the flag H is set to zero, photographing is executed without correcting the blurring.
