Imaging apparatus, imaging system, and imaging apparatus control method and program for setting a range of lens positions

摘要

In an imaging apparatus, an imager generates an imaged picture by converting incident light from a subject that is incident via a focus lens. A setting unit sets, as a movement range for the focus lens, a range of focus lens positions corresponding to imaging magnifications where the rate of change in the imaging magnification lies within a fixed range from a basis, the basis being an imaging magnification corresponding to the position of the focus lens. A focus controller configured to conduct focus control with respect to the subject by moving the focus lens in the set movement range.

1. An imaging apparatus comprising:
an imager configured to generate an imaged picture by converting incident light from a subject that is incident via a focus lens; a setting unit configured to set a range of focus lens positions, as a first movement range for the focus lens, corresponding to imaging magnifications for which rate of change in the imaging magnification lies within a fixed range, wherein the fixed range is based on an imaging magnification corresponding to an in-focus position of the focus lens; and a focus controller configured to conduct focus control with respect to the subject by moving the focus lens in the set first movement range.
