Abstract
A camera capable of blurring correction includes an acceleration sensor detecting camera-shake amount, and a blurring correcting device correcting blurring of image on the basis of the sensor output. When a lens of the camera is driven for automatic focusing, the blurring is not corrected using an output of the acceleration sensor. Accordingly, blurring is not wrongly corrected.
Claims21
A camera capable of correcting fluttering of an object image due to camera-shake, comprising:
- camera-shake detecting sensor for detecting said camera-shake and for outputting camera-shake information;
- taking lens for forming said object image;
- correcting means for shifting a position of the object image based on the camera-shake information such that the object image remains stationary during an exposure;
- driving means for driving an optical member in said taking lens;
- and
- control means for controlling said correcting means so that said correcting means does not use an output of said camera-shake detecting sensor when said optical member is being driven.
A camera capable of correcting fluttering of an object image due to camera-shake, comprising:
- a camera-shake detecting sensor for detecting said camera-shake and for outputting camera-shake information;
- correcting means for shifting a position of the object image based on the camera-shake information such that the object image remains stationary during an exposure;
- an actuator for performing predetermined operation for photographing;
- motor driving means for driving said actuator;
- and
- controlling means for forbidding fluttering correction based on camera-shake information obtained during operation of said driving means.
A camera capable of correcting fluctuation of an object image due to camera-shake, comprising:
- a power source;
- boosting means for boosting said power source voltage;
- charge means to be charged with said boosted voltage;
- flash means applied with power from said charge means for emitting flashlight;
- a sensor supplied with power by said power source for detecting a camera-shake;
- correcting means for correcting fluctuation of the object image due to said camera-shake according to the output of said sensor such that the object image remains stationary during an exposure;
- and
- controlling means for controlling said correcting means so that correction on the basis of said sensor output provided during operation of said boosting means is not performed.
A camera capable of correcting image movement due to camera-shake, comprising:
- exposure amount controlling means for controlling exposure to film;
- camera-shake detecting sensor for detecting said camera-shake;
- correcting means for correcting movement of the object image based on the output of said camera-shake detecting sensor;
- determining means for determining whether the movement can be properly corrected or not;
- auxiliary light means for lightening said object;
- and
- controlling means for making said auxiliary light means emit light when said determining means determines that said movement cannot be properly corrected in exposure.
A camera capable of correcting an object image due to camera-shake, comprising:
- a power source;
- a circuit consuming a large amount of power during operation, the voltage of said power source fluctuating due to the consumption;
- a sensor supplied with power by said power source for detecting a camera-shake;
- and
- correcting means for correcting movement of an object image due to said camera-shake according to the output of said sensor and not to correct on the basis of said sensor output that is provided during operation of said circuit.
Kindly cancel claim 14 without prejudice or disclaimer.
A camera comprising:
- (a) exposure amount controlling means for controlling exposure of film;
- (b) camera-shake detecting sensor for detecting camera-shake amount during exposure operation;
- (c) determining means for determining whether amount of fluctuation of an object image due to the camera-shake exceeds a predetermined value or not based on said camera-shake amount;
- (d) auxiliary light means for lighting said object;
- and
- (e) control means for controlling said auxiliary light means based on the result determined by said determining means.
A camera comprising:
- (a) exposure amount controlling means for controlling exposure to film;
- (b) camera-shake detecting sensor for detecting said camera-shake amount during exposure operation;
- (c) determining means for determining whether amount of fluctuation of an object image exceeds a predetermined value or not based on said camera-shake amount;
- and
- (d) control means for terminating exposure operation of said exposure amount controlling means when said determining means determines that the fluctuation amount exceeds a predetermined value.
