Abstract

A novel imaging apparatus capable of correcting a focus state by an AF detection value both simply and surely has been disclosed. The imaging apparatus comprises an auto-focus drive section for moving a lens, an AF processing section for calculating an AF detection value indicating the focus state from imaging data, a luminance processing section for calculating a luminance value from the imaging data, a correction section for calculating a corrected AF detection value by correcting the calculated AF detection value by the calculated luminance value, and a control section for controlling the auto-focus drive section based on the calculated corrected AF detection value. The imaging data is data not having been subjected to auto-exposure processing.
