Embodiment Construction

[0031] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0032] FIG. 1 is a partially cutaway perspective view showing a schematic configuration of an embodiment when the present invention is applied to a digital camera.

[0033] That is, FIG. 1 is a perspective view of a part of the camera body which is cut off and schematically shows the internal structure of the camera body.

[0034] The camera 1 of the present embodiment is composed of a camera main body 11 and a lens unit 12 that are separately constituted, and the camera main body 11 and the lens unit 12 are detachable from each other.

[0035] Furthermore, the lens unit 12 holds a photographic optical system 12a composed of a plurality of lenses and their driving mechanisms, etc. inside.

[0036] The photographing optical system 12a is composed of, for example, a plurality of optical lenses, etc., so that the image of the subject formed by the subject's beam is placed at a...

Abstract

The electronic imaging apparatus is equipped with a photographic optical system 12a which forms the optical image of a subject, an imaging device 27 which converts the optical image formed by the photographic optical system 12a into an electric signal, a dust-proof filter 21 which is arranged between the photographic optical system 12a and the imaging device 27 and which prevents dust or the like from being deposited on the photoelectric conversion surface of the imaging device 27 and a microcomputer 150 which makes the dust-proof filter 21 perform a dust removing operation by vibrating the filter 21 at prescribed frequencies and a camera operating switch SW 152 which can set a plurality of recording modes concerned with picture quality. Moreover the computer 150 makes the filter 21 perform the dust removing operation by vibrating the filter 21 by being linked with the photographing operation by the device 27 when a high-quality recording mode is set.

Description

Technical field [0001] The present invention relates to an electronic imaging device, and in particular to an electronic imaging device having a dustproof function capable of removing dust attached to constituent parts such as a camera system. Background technique [0002] Conventionally, as an example of technology related to the dust-proof function of an optical device used in an electronic imaging device, it has been proposed that a protective glass (dust-proof glass) that protects the imaging element is vibrated to wipe off and adhere to the dust-proof glass. Technology of the dust. For example, there is a technique disclosed in Japanese Patent Laid-Open No. 2002-204379 in which a piezoelectric element is used as a unit for vibrating the dustproof glass. The piezoelectric element responds to the applied voltage, expands and contracts, and vibrates the mounted dustproof glass in a predetermined cycle. [0003] In addition, there are operation modes that can perform shooting in...
