摘要:
A lens control unit as a control device includes a second position profile generator that generates a second target position profile indicating a target position of a second focus lens unit of a lens apparatus in driving the second focus lens unit. A trajectory shift amount calculator of the lens control unit calculates a shift between an ideal position of the second focus lens unit corresponding to a position of the first focus lens unit and a position of the second focus lens unit in the second target position profile. A correction value calculator corrects the target position of the second focus lens unit based on this shift.
