Benefits of technology

[0008] Accordingly, an object of the present invention is to provide an electronic image pickup device with a hand-shake compensation function which is capable of reducing the drive amount necessary for hand-shake compensation with a simple structure and thereby implementing downsizing of the drive member.

Problems solved by technology

Therefore, even with the electronic image pickup device with the hand-shake compensation function of Patent Document 3, in which the reflecting surface of the bending member for bending the optical axis is moved, the drive amount of the reflecting surface for hand-shake compensation is still so large that the drive member cannot be reduced in size to an enough extent.

Embodiment Construction

[0032] Hereinbelow, a camera-equipped portable electronic device using an electronic image pickup device with a hand-shake compensation function according to the present invention will be described in detail by way of embodiments thereof illustrated in the accompanying drawings.

[0033] First of all, a camera-equipped portable telephone as an example of a camera-equipped portable electronic device including an electronic image pickup device with a hand-shake compensation function according to the present invention will be explained with reference to FIGS. 6 to 8.

[0034]FIG. 6 is a perspective view showing an image-taking mode of a camera-equipped portable telephone 200 with a camera-use shake compensation unit contained therein. FIG. 7 is a perspective view of the camera-equipped portable telephone 200 of which a cover portion is closed as viewed from the rear side. Also, FIG. 8 is a block diagram of main part of the camera-equipped portable telephone 200 including the camera-use sha...

Abstract

There is provided an electronic image pickup device with a hand-shake compensation function capable of reducing drive amount necessary for shake compensation and achieving downsizing without increasing a size of a piezoelectric element or voltage to be applied. A lens L2 is attached to an output-side surface of a prism P1 for bending an optical axis, and the prism P1 and the lens L2 are integrated together. Upon occurrence of a hand-shake vibration, as the prism P1 is rotationally driven by a drive member 17, the lens L2 is also translated in a direction approximately perpendicular to the optical axis. By the moves of both prism P1 and lens L2, hand-shake compensation can be achieved with a small drive amount. Thus, the drive member 17 can be made smaller-size and compact, and the electronic image pickup device with a hand-shake compensation function can be reduced in size.

Description

[0001] This nonprovisional application claims priority under 35 U.S.C. §119(a) on Patent Application No. 2005-233025 filed in Japan on Aug. 11, 2005, the entire contents of which are hereby incorporated by reference. BACKGROUND OF THE INVENTION [0002] The present invention relates to an electronic image pickup device with a hand-shake compensation function, as well as camera-equipped portable electronic device, which is, for example, among camera-equipped portable electronic devices, capable of preventing image blurs due to hand shakes and vibrations or the like. In particular, the invention relates to an electronic image pickup device with a hand-shake compensation function, as well as camera-equipped portable electronic device, capable of making hand-shake compensations by driving a bending member for bending an optical axis in a bent optical system. [0003] In shooting with a camera-equipped portable electronic device, if an electronic image pickup device is given vibrations due t...
