Apparatus, method and non-transitory computer-readable medium storing program for controlling imaging environment of target object

A control method executed by a computer, comprising:

• detecting an object from a captured image generated by an image capture apparatus;
• determining, based on a range occupied by an image area representing the object in the captured image, a partial range relevant to the object, within an output range of an output apparatus that performs an output having influence on an image capture environment;
• determining, based on a feature value of the image area representing the detected object, an output setting of the output apparatus for the partial range;
• and
• applying, to the output apparatus, the output setting for the partial range determined for the object, wherein
• the output apparatus is an apparatus that outputs a background,
• the partial range determined for the object is a range to be a background of and around the object, within a range of a background output by the output apparatus, and
• the output setting determined for the object is a setting of a color of the background output to the partial range determined for the object, and
• the control method further comprises:
• in the determination of the output setting:
• computing, as a feature value of the image area representing the object, a representative point on a color space relating to a color of the image area and a representative value of hue of the image area;
• determining a point satisfying a predetermined relation with the representative point on the color space;
• determining, based on a color relevant to the determined point, a color of a background of the partial range determined for the object
• determining a color far from a computed representative value by a predetermined angle on a hue circle;
• and
• determining, based on the determined color, a color of a background of the partial range determined for the object.
