Embodiment Construction

[0025] The invention is described below with reference to the embodiments shown in the drawings. In this embodiment, the camera device 1 is a digital camera. The camera lens (ie, photographing lens) 67 of the camera device 1 has an optical axis LX.

[0026] By way of orientation in the embodiment, define x-direction, y-direction and z-direction (see figure 1 ). The x direction is a direction perpendicular to the optical axis LX. The y direction is a direction perpendicular to the optical axis LX and the x direction. The z direction is a direction parallel to the optical axis LX and perpendicular to the x direction and the y direction.

[0027] The relationship between the direction of gravity and the x, y, and z directions varies according to the orientation of the camera 1 .

[0028] For example, when the camera device 1 is held in a first horizontal orientation, in other words, when the camera device 1 is held horizontally with the upper surface of the camera device 1 f...

Abstract

A photographic apparatus comprises a movable platform, an acceleration sensor, and a controller. The movable platform has an imager, and is movable and rotatable in an xy plane. The acceleration sensor detects a first gravitational component and a second gravitational component. The first gravitational component is the component of gravitational acceleration in the x direction. The second gravitational component is the component of gravitational acceleration in the y direction. The controller calculates an inclination angle of the photographic apparatus formed by rotation of the photographic apparatus around the optical axis, as measured with respect to a level plane perpendicular to the direction of gravitational force, on the basis of a magnitude relation between the absolute value of the first gravitational component and the absolute value of the second gravitational component, and performs a first movement control of the movable platform for an inclination correction based on the inclination angle.

Description

technical field [0001] The present invention relates to a photographic device, and more particularly, to a photographic device that performs tilt correction. Background technique [0002] A class of image stabilization (also called anti-shake, but hereinafter simply referred to as "stabilization") devices for photographic devices is known. Depending on the amount of hand shake that occurs during imaging, the image stabilizer corrects the effect of hand shake by moving the image stabilizer lens or by moving the imager (imaging sensor) in the xy plane perpendicular to the optical axis of the photographing lens of the camera. [0003] Japanese Unexamined Patent Publication (KOKAI) No. 2006-71743 discloses an image stabilization device which calculates the amount of hand shake based on hand shake caused by yaw, pitch and roll, and then calculates the amount of hand shake based on the amount of hand shake (first, second and third hand shake angle) to perform stabilization.
