1. A lowpass filter control apparatus, comprising:
a lowpass filter controller configured to:
control lowpass characteristics of a variable lowpass filter, wherein
the variable lowpass filter is in an optical path of light that enters an imaging element, and
the imaging element includes a plurality of phase-difference pixels and a plurality of normal pixels; and
change a first cut frequency of the variable lowpass filter based on a magnification of a magnified display in a magnified display mode of an imaging device, wherein
the magnified display mode is a mode in which a shot image by the plurality of normal pixels is magnified and displayed on a display device, and
the first cut frequency of the variable lowpass filter is increased with an increase in the magnification of the magnified display.
