Abstract: An information processing device acquires positional information and posture information of a worker in a real space, the positional information and the posture information being used to update a position and posture of a virtual camera installed in a virtual space imitating a position and posture of the worker and the real space; determines whether the worker is in a stable state based on the positional information; and reduces an updating frequency of the positional information and the posture information when it is determined that the worker is not in the stable state, rather than when it is determined that the worker is in the stable state.

Abstract: A conversion method for converting luminance of a video, including a luminance value in a first luminance range, to be displayed on a display apparatus includes: acquiring a first luminance signal indicating a code value obtained by quantization of the luminance value of the video; and converting the code value indicated by the acquired first luminance signal into a second luminance value determined based on a luminance range of the display apparatus, the second luminance value being compatible with a second luminance range with a maximum value smaller than a maximum value of the first luminance range and larger than 100 nit. This provides the conversion method capable of achieving further improvement.
