Abstract
An electronic apparatus that can enhance the accuracy of detection of halation by taking into account the influence of halation on visibility of an object, and also effectively suppress the influence of halation independently of the type of a light source. An evaluation unit evaluates the luminance of the object based on an exposure level at which image data of the object is acquired. A detection unit detects t halation based on the luminance of the object, a first luminance area having a higher luminance than a first luminance threshold value, and a distribution status of another luminance area which is an area having a lower luminance than the first luminance area and is distributed around the first luminance area.
