ている。2. Description of the Related Art Video cameras have become smaller and lighter due to the practical use of solid-state imaging devices, and are rapidly becoming popular due to their high magnification and multifunctionality. Recently, exposure control and focus control have been automated, and there are fewer failures in shooting due to these. However, video cameras are usually used in a handheld position, and as they become lighter and more compact, the possibility of camera shake increases. It is no exaggeration to say that the screen always shakes when hand-held, and such screen shake is causing a decline in image quality and unpleasant situations such as video sickness, which are becoming a problem.

The former uses a gyro mechanism to stabilize the lens barrel system regardless of the shake of the camera body, but it has the disadvantage of being large and heavy. The latter uses a variable apex angle prism to decenter the optical axis of the photographing optical system in a direction that offsets the shake of the camera body, and has the advantage of minimizing the size and weight of the camera. For example, a variable apex angle prism has two transparent plates that are separated in the optical axis direction, the circumference of which is closed with a bellows, and a liquid with a predetermined refractive index is filled inside.The transparent plate on the subject side is aligned with the central axis. The imaging optical axis is decentered by tilting it with respect to a plane perpendicular to (the optical axis at the neutral position).

There is a configuration in which the focusing lens of the camera is moved. This automatic focus adjustment device is set so that the beams of light emitted from the light emitting elements toward the subject intersect at a predetermined position on the photographing optical axis of the photographing optical system. Therefore, when a shake correction device using the above-mentioned variable apex angle prism is incorporated into a camera using such an automatic focus adjustment device, the optical axis of the photographic optical system and the optical axis of the light emitting element of the automatic focus adjustment device are There is a problem that a shift occurs between the two, making it impossible to achieve accurate focusing.

位置を判別する。The structure of the shake detection sensor 32 is as follows. That is, a liquid 42 having a predetermined refractive index is placed in a cylindrical case 40, and a floating body 44 that is rotatable around a predetermined rotation axis is suspended in the liquid 42. The floating body 44 is made of a magnetic material and forms a closed magnetic circuit with a permanent magnet 46 outside the cylindrical case 40. Due to this closed magnetic circuit, the floating body 44 remains stationary at a position closest to the permanent magnet 46 when there is no camera shake. 48 is a light emitting element that irradiates the floating body 44 with a beam of light; 50 is a light receiving element into which the reflected light from the floating body 44 is incident; and 52 is a position detection circuit that detects the position of incidence of the reflected light on the light receiving element 50. The light receiving element 50 is composed of, for example, a two-split optical sensor, and the position detection circuit 52 is connected to the light receiving element 5.
From the two outputs of 0, the incident position of the reflected beam from the floating body 44 is determined.

The permanent magnet 46, the light emitting element 48, and the light receiving element 50 also swing, but the floating body 44 tends to remain stationary due to inertia. Therefore, the floating body 44 rotates relative to the cylindrical case 40. The reflected light is incident on the light receiving element 50 at a position corresponding to the amount of rotation of the float 44. The light receiving element 50 generates an electric signal according to the incident position of light. Position detection circuit 5
2 outputs a light incident position signal to the control circuit 34 in accordance with the output of the light receiving element 50. This allows the control circuit 34 to know the amount of camera shake.

The apex angle of the apex angle prism 10 is driven and controlled. That is, the control circuit 34 applies a difference signal between the outputs of the position detection signals 52 and 68 to the VAP drive circuit 12, and the VAP drive circuit 12 supplies a corresponding drive current to the coil 62.
