1. An information processing device comprising:
a position/posture estimation unit configured to estimate a position and a posture of an imaging unit or a mobile body that moves integrally with the imaging unit based on a feature point of a captured image captured by the imaging unit; and
a control unit configured to
control brightness of the captured image so that a ground image region included in the captured image has appropriate exposure,
set a weight coefficient for each of a plurality of blocks in a photometry area including the plurality of blocks set in an image area of the captured image, and
specify a block set in the ground image region among the plurality of blocks,
wherein the control unit sets the weight coefficient for each of the plurality of blocks based on the specified block set in the ground image region, and
wherein the position/posture estimation unit and the control unit are each implemented via at least one processor.
