1. An imaging apparatus comprising:
an imaging element that images a subject through an imaging optical system; and
a processor,
wherein the processor is configured to:
detect a subject area as a second area from pixel data obtained by the imaging element at a second time point; and
output, to a lens drive mechanism of the imaging optical system, a control signal generated by selectively using a first focus position based on data of the second area in the pixel data obtained at the second time point and a second focus position based on data of the second area in pixel data obtained by the imaging element at a third time point after the second time point,
wherein the processor is configured to output the control signal generated by using the second focus position to the lens drive mechanism in a case where a difference between a position of a first area, which is detected as the subject area from pixel data obtained by the imaging element at a first time point before the second time point, and a position of the second area is less than or equal to a predetermined threshold value, and output the control signal generated by using the first focus position to the lens drive mechanism in a case where the difference is more than the predetermined threshold value.
