Title: Shake preventing device and image pickup device provided therewith
Inventor: KANEDA NAOYA
IPC: H04N5/232
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To eliminate correction in accordance with the elevation angle of a camera in the shake preventing device and to realize accurate shake correction by arranging a shake detection means on a yaw side on a camera side. SOLUTION: This device is provided with a photographing lens 1, a solid-state image pickup element 2 such as a CCD and a variable apex angle prism 3 functioning as a shake correction means arranged ahead of the lens 1. A piezoelectric vibration gyro 4 detects a shake component (rotational amount of the camera by camera shake) in a pitch direction (vertical direction) and the shake detection means 5 similarly detects the shake component in a yaw direction (horizontal direction). Thus, at least the shake detection means 5 on the yaw side is arranged on the camera side. Namely, horizontal shake, which appears on an image-formation surface, is mostly caused by an axial component, so that the shake prevention is accurately performed regardless of the state of the elevation angle by arranging at least the sensor on the yaw side on the camera side.
