Abstract:
1. An imaging apparatus comprising: an imaging unit configured to capture an image of an object to obtain an image signal; a detection unit configured to set a detection area in a captured image based on the image signal obtained by the imaging unit and calculate a detection value from an image signal in the detection area; an exposure adjustment unit configured to perform exposure adjustment; a control unit configured to control the exposure adjustment unit so that the detection value becomes equal to a predetermined value; and a presentation-image detecting unit configured to detect whether a presentation image presented by an image presentation device is included in the captured image on the basis of a difference in luminance of a region in the captured image and a determination of whether an aspect ratio of the region is within a predetermined range, wherein when the presentation-image detecting unit detects the presentation image, the detection unit sets the detection area in a location different from a location of the detected presentation image.
