Abstract
Abstract A camera having a blurring correction apparatus according to the present invention includes a photographic lens for forming an image of an object to be photographed, a detecting apparatus for detecting the degree of movement of the formed image of the object, a correcting apparatus operative at least during exposure time for correcting the position of the image of the object in response to a detection output of the detecting apparatus so as to compensate the movement of the image of the object, a setting apparatus for setting exposure time, a calculating apparatus for calculating the amount of movement of the image of the object produced during exposure time based on the detection output of the detecting apparatus and the set exposure time, and a prohibiting apparatus for prohibiting the operation of the correcting apparatus when the amount of movement of the image of the object produced during exposure time is smaller than a predetermined value.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
91 words
An interchangeable lens that can be interchangeably mounted on a camera body which is capable of detecting a degree of movement of an object image in a direction perpendicular to an optical axis of the lens, said lens comprising: an optical system operable to compensate the movement of the object image in a direction perpendicular to the optical axis of the lens; means for driving said optical system so as to compensate the movement of the object image; and means for controlling said driving means by means of a pulse signal.
Claim 2
Dependent Claim
91 words
An interchangeable lens that can be interchangeably mounted on a camera body which is capable of detecting a degree of movement of an object image in a direction perpendicular to an optical axis of the lens, said lens comprising: an optical system operable to compensate the movement of the object image in a direction perpendicular to the optical axis of the lens; means for driving said optical system so as to compensate the movement of the object image; and means for controlling said driving means by means of a pulse signal.
Claim 3
Dependent Claim
15 words
The interchangeable lens according to claim 1, wherein said driving means is a pulse motor.
Claim 4
Dependent Claim
15 words
The camera according to claim 1, wherein said controlling means operates during an exposure time.
Claim 5
Dependent Claim
23 words
The camera according to claim 1, wherein said optical system has an optical element which is movable to keep the object image stable.
Claim 6
Dependent Claim
95 words
A camera comprising: means for detecting a degree of movement of an object image in a direction perpendicular to an optical axis of the camera, wherein said detecting means detects the degree of movement during an exposure time; an optical system operable to compensate the movement of the object image in a direction perpendicular to the optical axis of the lens; means for driving said optical system so as to compensate the movement of the object image; and means, operable during the exposure time, for controlling said driving means by means of a pulse signal.
Claim 7
Dependent Claim
95 words
A camera comprising: means for detecting a degree of movement of an object image in a direction perpendicular to an optical axis of the camera, wherein said detecting means detects the degree of movement during an exposure time; an optical system operable to compensate the movement of the object image in a direction perpendicular to the optical axis of the lens; means for driving said optical system so as to compensate the movement of the object image; and means, operable during the exposure time, for controlling said driving means by means of a pulse signal.
Claim 8
Dependent Claim
14 words
The camera according to claim 5, wherein said driving means is a pulse motor.
Claim 9
Dependent Claim
33 words
The camera according to claim 5, wherein said optical system is an interchangeable lens that can be interchangeably mounted on a camera body and said driving means is mounted on the interchangeable lens.
Claim 10
Dependent Claim
23 words
The camera according to claim 5, wherein said optical system has an optical element which is movable to keep the object image stable.
