Abstract: A method for controlling an illuminator illuminating a scene monitored by a camera comprises determining whether an object of interest is present in the scene; upon at least one object of interest being determined to be present in the scene, setting a saturation threshold to a first value; or upon no object of interest being determined to be present in the scene, setting the saturation threshold to a second value being lower than the first value. The method further comprises identifying saturated pixels in an image of the scene captured by the camera; determining a ratio between a saturated area comprising the saturated pixels and a total area of the image; and upon the ratio being above the saturation threshold, decreasing a degree of illumination from the illuminator.

Abstract: An image capturing apparatus includes a setting unit and an extension unit. The setting unit sets a range of a restricted area where browsing is restricted in an image captured by an image capturing unit that captures an image formed by a lens. The extension unit extends a size of the restricted area with respect to a real space in a manner that browsing of a second area in the real space, which includes a first area and also is wider than the first area, is restricted in a case where the restricted area where browsing of the first area in the real space is restricted is set by the setting unit and also an image capturing area where image capturing can be executed by the image capturing unit is extended.
