Information processing apparatus, information processing method, and non-transitory computer-readable storage medium

An information processing method comprising:

• acquiring a plurality of pieces of input data having a first bit depth;
• converting the bit depth of a piece of input data to a second bit depth that is lower than the first bit depth;
• converting the bit depth of another piece of input data to the second bit depth, and extract features from data obtained by integrating the piece of data whose bit depth is converted to the second bit depth and the other piece of input data whose bit depth is converted to the second bit depth;
• and
• extending the bit depth of the features to a third bit depth that is higher than the second bit depth.

A non-transitory computer-readable storage medium storing a computer program that, when read and executed by a computer, causes the computer to:

• acquire a plurality of pieces of input data having a first bit depth;
• convert the bit depth of a piece of input data to a second bit depth that is lower than the first bit depth;
• convert the bit depth of another piece of input data to the second bit depth, and extract features from data obtained by integrating the piece of data whose bit depth is converted to the second bit depth and the other piece of input data whose bit depth is converted to the second bit depth;
• and
• extend the bit depth of the features to a third bit depth that is higher than the second bit depth.
