Abstract
Abstract There is provided an optical apparatus includes a sensor for detecting vibration that is caused in the optical apparatus, a blur correction unit for correcting blur of an image obtained by the optical system, a control unit for controlling driving of the blur correction unit according to an output of the sensor, a finder for observing the image obtained by the optical system, the finder having an eyepiece optical system; and a display for displaying the image obtained by the optical system, in which the control unit changes a vibration detection frequency band depending on whether the finder is used or the display is used.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
105 words
An optical apparatus having an optical system, comprising: a sensor for detecting vibration that is caused in said optical apparatus; a blur correction unit for correcting blur of an image obtained by said optical system; a control unit for controlling driving of said blur correction unit according to an output of said sensor; a finder for observing the image obtained by said optical system, said finder having an eyepiece optical system; and a display for displaying the image obtained by said optical system, wherein said control unit changes a vibration detection frequency band depending on whether said finder is used or said display is used.
Claim 2
Dependent Claim
105 words
An optical apparatus having an optical system, comprising: a sensor for detecting vibration that is caused in said optical apparatus; a blur correction unit for correcting blur of an image obtained by said optical system; a control unit for controlling driving of said blur correction unit according to an output of said sensor; a finder for observing the image obtained by said optical system, said finder having an eyepiece optical system; and a display for displaying the image obtained by said optical system, wherein said control unit changes a vibration detection frequency band depending on whether said finder is used or said display is used.
Claim 3
Dependent Claim
15 words
An optical apparatus according to claim 1 , wherein said finder is an optical finder.
Claim 4
Dependent Claim
28 words
An optical apparatus according to claim 1 , wherein said finder is an electronic finder for observing the image displayed on said display via said eyepiece optical system.
Claim 5
Dependent Claim
41 words
An optical apparatus according to claim 1 , wherein, when said display is used, said control unit extends the vibration detection frequency band of said sensor to a frequency area lower than that at the time when said finder is used.
Claim 6
Dependent Claim
45 words
An optical apparatus according to claim 1 , further comprising a detection unit for detecting whether or not a photographer has approached said finder, wherein said control unit changes a control characteristic of said blur correction unit according to an output of said detection unit.
Claim 7
Dependent Claim
41 words
An optical apparatus according to claim 1 , further comprising a switch for switching display and non-display states of said display, wherein said control unit changes a control characteristic of said blur correction unit according to the state of said switch.
