Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
81 words
An apparatus comprising: a vibration correction device for correcting a vibration of an image; a switch for turning on or off said vibration correction device; 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
81 words
An apparatus comprising: a vibration correction device for correcting a vibration of an image; a switch for turning on or off said vibration correction device; 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
