Problems solved by technology

In addition, the driving device 1013 cannot move the correcting lens 1011 beyond its rated output, so in practice, the range in which the driving device 1013 can move the correcting lens 1011 is sometimes limited to the rated output range Ri narrower than the movable range R (at the left rated output position α and the right rated output position β)

Embodiment approach 1

[0029] Regarding other embodiments of the present invention, based on Figure 1 ~ Figure 4 described as follows.

[0030]

[0031] figure 1 It is a figure which shows the calibration apparatus 1 and calibration method of this embodiment. Such as figure 1As shown, the correction device 1 includes a correction lens (optical element) 11 , an actuator coil (drive device) 13 , a position detection sensor (position detection device) 15 , and a control unit (intermediate position correction unit) 20 . With such a configuration, the correction lens 11 is moved by allowing a current within the rated current to flow in the actuation coil 13 to eliminate vibration caused by hand shake, and the unused area can be reduced compared to before correction. Each component included in the calibration device 1 will be described in detail below.

[0033] The correction lens 11 is incorporated into an imaging device or the like together with an actuator coil 1...

Embodiment approach 2

[0067] based on Figure 5 Other embodiments of the present invention will be described below. In addition, for the sake of convenience of description, members having the same functions as those described in the above-mentioned embodiments are given the same reference numerals and their descriptions are omitted.

[0068]

[0069] Figure 5 It is a cross-sectional view showing the configuration of the imaging device 100A and the calibration device 1A of the present embodiment. Here, the imaging device 100A is equipped with image 3 The camera device 100 shown has the same structure, but as Figure 5 As shown, it differs from the imaging device 100 in further including an interactive control unit (calibration instruction information generation unit) 50 and an interface 130 for intermediating between the interactive control unit 50 and the calibration device 1A. In addition, the calibration device 1A is equipped with figure 1 The correction device 1 shown in etc. has the s...

Embodiment approach 3

[0074] The following is based on Figure 6 Other embodiments of the present invention will be described. In addition, for convenience of description, members having the same functions as those described in the above-mentioned embodiments are denoted by the same reference numerals, and descriptions thereof are omitted.

[0075]

[0076] Figure 6 It is a cross-sectional view showing the configuration of the imaging device 100B and the calibration device 1B of the present embodiment. Here, the imaging device 100B is equipped with image 3 The imaging device 100 shown has the same configuration, and the calibration device 1B has the same configuration as image 3 The calibration device 1 shown has the same structure, but as Figure 6 As shown, the correction device 1B is different in that it moves the image sensor (optical element) 102 instead of the correction lens.

[0077] That is, the calibration device 1B includes: an image sensor 102 housed in the space between the f...

Abstract

In order to provide a calibration device and the like suitable for image stabilization, this calibration device (1) is provided with a stabilizing lens (11), an actuator coil (13), and a control unit (20) that calibrates the center (p) of the range of motion (R) of the stabilizing lens (11) to the point (pa) midway between a right-edge position (b) and a left rated-output position (α), said left rated-output position (α) being the closest position to a left-edge position (a) to which the stabilizing lens (11) can move via the application, to the actuator coil (13), of a current less than or equal to a rated current.

Description

technical field [0001] The present invention relates to a correction device for correcting a movable range of an optical element such as a lens, and an imaging device and the like provided with the correction device. Background technique [0002] In imaging devices such as cameras, digital cameras, video cameras, and binoculars, sometimes the captured video is disturbed by user's hand shake. Therefore, for such imaging devices, development of a hand-shake correction function that reduces adverse effects on the imaging function due to hand-shake is being developed. Here, examples of methods for realizing the hand-shake correction function include a device shift method, a lens shift method, and a sensor shift method. Among them, in the lens shift method, a correction lens including a vibrating gyro mechanism or the like is built into the imaging device, and the optical axis of the optical system is corrected by moving the correction lens in a direction to eliminate vibration ...
