Abstract
An imaging device comprising a light transmissive member 18 having light transmissive character, a vibration member 20 causing bending vibration for the light transmissive member, a driving portion 56 for driving the vibration member 20, wherein the driving portion 56 causes bending vibration of the light transmissive member at a first frequency along with a first direction and causes bending vibration of the light transmissive member 18 at a second frequency along with a second direction which is different from said first frequency.
Claims44
An imaging device comprising;
- a light transmissive member having light transmissive character, provided between an optical system and an image pick-up portion that obtains an image from the optical system,
- a vibration member that causes bending vibration of said light transmissive member, the vibration member being provided on the light transmissive member, and
- a driving portion connected electrically to said vibration member so as to drive said vibration member and cause bending of said light transmissive member at a first frequency along with a first direction, and bending of said light transmissive member at a second frequency, which is different from said first frequency, along with a second direction which crosses said first direction.
An imaging device comprising;
- a light transmissive member having light transmissive character, provided between an optical system and an image pick-up portion that obtains an image from the optical system,
- a vibration member that causes bending vibration of said light transmissive member, and
- a driving portion that drives said vibration member, wherein;
- said driving portion causes bending vibration of said light transmissive member along with a first direction and causes bending vibration of said light transmissive member along with a second direction which crosses said first direction at a different timing from the bending vibration along with said first direction.
