Problems solved by technology

However, in the laser autocollimators 6 and 7, the inclination angle and the rotation angle are only approximately ±2.5 deg.
Therefore, when the swing angle range of the movable module 2 and the rotation angle range of the storage body 3 are large, the measurable ranges of the laser autocollimators 6 and 7 will be exceeded, and the measurable ranges of the optical equipment 1 in each direction cannot be measured. Moving part angle characteristics

Embodiment Construction

[0050] Next, an embodiment of the shake correction characteristic evaluation apparatus for implementing the optical device with a shake correction function of the present invention will be described.

[0051] image 3 (a) is a system configuration diagram of an inspection device 10 constituting a shake correction characteristic evaluation device of an optical device with a shake correction function 11 according to an embodiment of the present invention, Figure 4 is the block diagram of the circuit. In this specification, the three axes of XYZ are directions perpendicular to each other. +X represents one side of the X-axis direction, -X represents the other side, +Y represents one side of the Y-axis direction, and -Y represents the other side. One side, use +Z to indicate one side in the Z-axis direction, and use -Z to indicate the other side. The Z-axis direction is a direction along the optical axis L of the camera 13 a mounted on the movable module 13 when the movable mod...

Abstract

The invention provides a shaking correction feature evaluation device of an optical device with a shaking correction function. A laser autocollimator is used, so there is no need to arrange a mirror plane on a product. A rotation bench is used, so there is no need to waste time to change a measurement direction, and rotation shaking correction features can be cheaply evaluated. The device allows astorage body to serve as a correction body to rotate by taking an optical axis L of a camera as a rotation shaft through control of a control IC. By use of a camera, images of multiple displaying light emitting points are shot. According to change of gradients of the straight lines of the light emitting points in each image, image shaking around the optical axis L of the camera is known. In thisway, based on the gradients of the straight lines in multiple images, driving features of a rotation actuator when image shaking of a to-be-shot body image around the optical axis L of the camera is corrected are known. According to the driving features, by use of the above system, rotation shaking correction features of the optical device are evaluated.

Description

technical field [0001] The present invention relates to a shake correction characteristic evaluation device which evaluates the shake correction characteristic of an optical device with a shake correction function which corrects image shake of a subject image, and particularly relates to a shake correction characteristic evaluation device which can accommodate The housing body of the movable module is rotated to correct the image shake of the subject image generated around the optical axis of the camera included in the movable module, and the evaluation of the shake correction characteristic is characteristic. Background technique [0002] Conventionally, as a shake correction characteristic evaluation device of such an optical device with a shake correction function, there is a shake correction camera inspection device disclosed in Patent Document 1, for example. The shake correction camera inspection device is composed of a camera side part, a communication tool side part,...
