Information processing apparatus, image forming apparatus, information processing method, and storage medium

An information processing method that generates a signal value for forming an image of an object as a recording layer on a recording medium, the information processing method comprising:

• inputting a characteristic of specular reflection light as a reflected light component in a specular reflection direction with respect to a surface of the object;
• inputting a characteristic of internal diffuse reflection light as a reflected light component after scattering and absorption in the object;
• inputting a characteristic of surficial diffuse reflection light as a reflected light component diffused by the surface of the object;
• deriving, based on the characteristic of the internal diffuse reflection light, a first signal value for a first recording layer to be formed on the recording medium;
• and
• deriving, based on the characteristic of the specular reflection light and the characteristic of the surficial diffuse reflection light, a second signal value for a second recording layer different from the first recording layer to be formed on the recording medium.

A non-transitory computer-readable storage medium storing instructions that, when executed by a computer, cause the computer to perform an information processing method that generates a signal value for forming an image of an object as a recording layer on a recording medium, the information processing method comprising:

• inputting a characteristic of specular reflection light as a reflected light component in a specular reflection direction with respect to a surface of the object;
• inputting a characteristic of internal diffuse reflection light as a reflected light component after scattering and absorption in the object;
• inputting a characteristic of surficial diffuse reflection light as a reflected light component diffused by the surface of the object;
• deriving, based on the characteristic of the internal diffuse reflection light, a first signal value for a first recording layer to be formed on the recording medium;
• and
• deriving, based on the characteristic of the specular reflection light and the characteristic of the surficial diffuse reflection light, a second signal value for a second recording layer different from the first recording layer to be formed on the recording medium.
