Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
70 words
An apparatus comprising: a vibration correction device for correcting a vibration of an image; and a limiting device for calculating a ratio of an amount of vibration correction to be effected by said vibration correction device in accordance with an image shake condition, to a maximum value of vibration correction by said vibration correction device, and limiting an operation of said vibration correction device in correspondence with a calculation result.
Claim 2
Independent Claim
70 words
An apparatus comprising: a vibration correction device for correcting a vibration of an image; and a limiting device for calculating a ratio of an amount of vibration correction to be effected by said vibration correction device in accordance with an image shake condition, to a maximum value of vibration correction by said vibration correction device, and limiting an operation of said vibration correction device in correspondence with a calculation result.
Claim 3
Dependent Claim
20 words
The apparatus according to claim 1 , wherein said vibration correction device corrects vibration of the image by signal processing.
Claim 4
Dependent Claim
18 words

Claim 5
Dependent Claim
54 words
The apparatus according to claim 1 , further comprising vibration detection device for detecting vibration, and wherein said vibration correction device operates in accordance with an output from said vibration detection device, and said limiting device limits the operation of said vibration correction device in accordance with the output from said vibration detection device.
Claim 6
Dependent Claim
45 words
The apparatus according to claim 1 , wherein said limiting device determines a value of a limiting amount in proportion to the n-th power (n is an integer not less than 1) of a value of the correction amount determined by said vibration correction device.
Claim 7
Dependent Claim
15 words
The apparatus according to claim 1 , wherein said apparatus comprises an image sensing apparatus.
Claim 8
Dependent Claim
13 words
The apparatus according to claim 1 , wherein said apparatus comprises a camera.
