距離検出装置および距離検出方法
Document Type and Number:
Japanese Patent JP6695910
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a tremor correction device and range-finding meter that can resolve a disadvantage in which a correction lens is driven in spite of the fact that a tremor is intentional panning of users.SOLUTION: A tremor correction device comprises: a collimation optical system 300 that collimates an object to form an optical image of a collimation object; a range-finding signal processing unit 700 that repetitively range-finds with respect to the collimation object, and sequentially outputs range-finding signals; a tremor detection unit 400 that detects a tremor to be applied to the collimation optical system, and outputs a tremor signal; a correction member that is disposed in an optical path of the collimation optical system, and corrects an image tremor of the optical image attributed to the tremor to be applied o the collimation optical system; an amount-of-drive calculation unit 500 that calculates an amount of drive of the correction member on the basis of the output from the range-finding signal processing unit and the tremor signal from the tremor detection unit; and a driving unit 620 that drives the correction member on the basis of the calculated amount of drive.SELECTED DRAWING: Figure 1
