Title:
CONTROL DEVICE, LENS DEVICE, IMAGING DEVICE, CONTROL METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2022185273
Kind Code:
A
Abstract:
To provide a control device capable of appropriately maintaining a positional relation of a plurality of focus lenses even while driving to a target position of the plurality of focus lenses during focusing, a lens device, an imaging device, lens control, and a program.SOLUTION: A control device calculates target positions of a first focus lens and a second focus lens in each prescribed period. The control device includes an acquisition part for acquiring positional characteristic data showing a relation between the positions of the first focus lens and the second focus lens and a subject distance, and an image surface moving speed, and a calculation part for calculating the subject distance of a target by using information on the image surface moving speed and the subject distance, and calculating the target positions of the first focus lens and the second focus lens by using the position characteristic data and the subject distance of the target.SELECTED DRAWING: Figure 8
