Abstract
Provided is an information processing device including: a control unit that performs position detection of an object, on which a light emitting unit or a reflective material is provided, on the basis of a captured image acquired by imaging of emitted light or reflected light of the object in a direction facing a side, on which the light emitting unit or the reflective material is provided, of the object, wherein the control unit adjusts algorithm for the position detection of the object according to an illuminance detection result of external light including at least a wavelength of the emitted light or the reflected light.

- and
- detect the position of the object based on execution of the determined at least one position detection algorithm with respect to a captured image acquired by imaging of one of the emitted light or the reflected light by the object,
- wherein the imaging is done in a direction facing a side, on which one of the light emitting element or the reflective material is present, of the object.

An information processing device, comprising:
- at least one processor configured to:
- select at least one position detection algorithm from a plurality of position detection algorithms for detection of a position of an object, which includes one of a light emitting element or a reflective material, based on an illuminance detection result of external light which includes at least a wavelength of one of emitted light or reflected light of the object;
- and
- detect the position of the object based on execution of the selected at least one position detection algorithm with respect to a captured image acquired by imaging of one of the emitted light or the reflected light of the object in a direction facing a side, on which the light emitting unit or the reflective material is present, of the object, wherein
