1. An information processing apparatus comprising:
a receiving circuit that receives an instruction to change a position and orientation of a virtual viewpoint based on an instruction to display a target object on a screen in an enlarged view or an instruction to display the target object on the screen in a reduced view;
an acquisition circuit that acquires three-dimensional shape information indicating a three-dimensional shape of the target object;
a deriving circuit that derives, based on the instruction to change the position and orientation of the virtual viewpoint and the three-dimensional shape information, a percentage of an area occupied by the target object in a displayed image;
a setting circuit that sets, based on the percentage, an illumination ratio for mixing a first illuminating condition in which light is irradiated to the target object from one direction using a virtual spot light source and a second illuminating condition in which light is irradiated to the target object from a plurality of directions using an environmental-light map; and
a display control circuit that adjusts, based on the illumination ratio, the illuminating condition of the displayed image, and displays the displayed image,
wherein a ratio of the first illuminating condition in the illumination ratio in a case where the percentage is a first percentage is larger than the ratio of the first illuminating condition in the illumination ratio in a case where the percentage is a second percentage smaller than the first percentage.
