Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
109 words
An apparatus adapted to an image blur prevention apparatus having a movable member movable for image blur prevention, comprising: a control portion for, corresponding to an output of a blur detection device for detecting a blur state, controlling an absolute position of said movable member in accordance with a blur signal corresponding to a detected blur displacement, said control portion controlling the absolute position of said movable member so that the blur signal and the absolute position satisfy a predetermined relationship; and a regulating portion for regulating the movement of the movable member in accordance with said blur signal when said blur signal becomes larger than a predetermined level.
Claim 2
Independent Claim
109 words
An apparatus adapted to an image blur prevention apparatus having a movable member movable for image blur prevention, comprising: a control portion for, corresponding to an output of a blur detection device for detecting a blur state, controlling an absolute position of said movable member in accordance with a blur signal corresponding to a detected blur displacement, said control portion controlling the absolute position of said movable member so that the blur signal and the absolute position satisfy a predetermined relationship; and a regulating portion for regulating the movement of the movable member in accordance with said blur signal when said blur signal becomes larger than a predetermined level.
Claim 3
Dependent Claim
31 words
An apparatus according to claim 1, wherein said regulating portion comprises means for causing the movable member not to perform the operation corresponding to the output from the blur detection device.
Claim 4
Dependent Claim
32 words
An apparatus according to claim 1, wherein said regulating device comprises means for performing the regulation in accordance with that the level of the blur signal is larger than the predetermined level.
Claim 5
Dependent Claim
30 words
An apparatus according to claim 3, further comprising release means for releasing the regulation by said regulating portion in accordance with that the level is smaller than the predetermined level.
Claim 6
Dependent Claim
47 words
An apparatus according to claim 4, wherein said release means comprises means for releasing the regulation by said regulating portion in accordance with that a state where the level of the blur signal is smaller than the predetermined level, has been kept for a predetermined time period.
Claim 7
Dependent Claim
26 words
An apparatus according to claim 1, wherein said blur detection device comprises means for detecting a fluctuation of an apparatus to which image blur is prevented.
