Shake correction characteristic evaluation device for optical equipment with shake correction function

Abstract

The invention provides a shake correction characteristic evaluation device of an optical device with a shake correction function. The use of a laser autocollimator eliminates the need to install a mirror on the product, and the use of a turntable eliminates time-consuming changes in the measurement direction, enabling inexpensive evaluation of its rotational shake correction characteristics. In this shake correction characteristic evaluation device, the storage body is rotated as a correction body with the optical axis L of the camera as the rotation axis under the control of the control IC, and a plurality of images showing luminous points are captured by the camera. Image shake around the optical axis L of the camera can be understood from changes in the inclinations of the straight lines connecting the light-emitting points in the respective images. Therefore, the driving characteristics of the rotary actuator when correcting the image shake of the subject image around the optical axis L of the camera can be known based on the inclinations of the straight lines in the plurality of images. Evaluate the rotational shake correction characteristics of optical devices.

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.

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.
