For example, in Japanese Patent Application Laid-open No. 2008-232665, a pressure measurement film is used as a reference using a density value-pressure value conversion table that shows the relationship between the brightness value and pressure value read by a scanner that serves as a reference for the pressure measurement film. A pressure analysis system is described that converts brightness values read by a scanner other than the above scanner into pressure values.

There is a known technique for deriving the pressure value applied to a coloring member based on a coloring member image obtained by photographing a coloring member that develops color with a density corresponding to the applied pressure. When deriving the pressure value, reference data such as a conversion table that associates the color density value with the pressure value is used. The reference data is created, for example, based on representative characteristics that are representative of the coloring characteristics of the coloring member, and is typically provided by a manufacturer that manufactures the coloring member. However, there are individual differences in the coloring characteristics of coloring members, and they may deviate from the representative characteristics. That is, the pressure value derived using uniform reference data provided by the manufacturer may deviate from the actual value.

The disclosed technology has been made in view of the above points, and aims to improve the accuracy of the pressure value derived based on the coloring member image.

An information processing device according to the disclosed technology includes at least one processor. The processor acquires a first color-forming member image obtained by photographing a color-forming member that develops color at a density corresponding to the applied pressure, and calculates the pressure value in a designated area of the first color-forming member image into a color-forming density. It is derived using each of a plurality of mutually different reference data in which values and pressure values are associated with each other.

The processor may display the first coloring member image on the display screen, and may receive designation of a region within the first coloring member image from which a pressure value is to be derived using each of the plurality of reference data. The processor may display each of the pressure values derived using each of the plurality of reference data on the display screen. The processor may accept selection of one of the plurality of reference data. The processor may select reference data corresponding to a pressure value closest to a predetermined value from among the pressure values derived using each of the plurality of reference data. The processor uses a plurality of reference data when deriving the pressure value applied to the coloring member corresponding to the second coloring member image based on the second coloring member image that is the same as or different from the first coloring member image. Among them, one selected reference data may be referred to.

The information processing method according to the disclosed technology acquires a first color-forming member image obtained by photographing a color-forming member that develops color at a density corresponding to applied pressure, and captures a designated area of the first color-forming member image. At least one processor included in the information processing device executes a process of deriving the pressure value in using each of a plurality of mutually different reference data in which color density values and pressure values are associated with each other.

FIG. 1 is a diagram showing how a coloring member 50 is photographed using an information processing device 10 according to an embodiment of the disclosed technology. The information processing device 10 has a function of deriving a pressure value applied to the coloring member based on a coloring member image obtained by photographing the coloring member 50 that develops color with a density corresponding to the applied pressure.

FIG. 2 is a plan view showing the coloring surface of the coloring member 50 to which pressure is applied. The coloring member 50 is a film-like member in which a coloring agent layer in which microcapsules containing a colorless dye are dispersed and a coloring agent layer having a coloring agent are laminated. When pressure is applied to the color developing member 50, the microcapsules are destroyed, the colorless dye is adsorbed to the color developer, and color is developed through a chemical reaction. Colorless dyes are encapsulated in multiple types of microcapsules with different sizes and strengths. The amount of colorless dye flowing out from the destroyed microcapsules and adsorbed to the color developer changes depending on the pressure applied to the color developing member 50. Therefore, the coloring member 50 develops a color with a density corresponding to the applied pressure. By observing the coloring surface of the coloring member 50, the magnitude (pressure value) and pressure distribution of the pressure applied to the coloring member 50 can be grasped. As the coloring member 50, it is possible to use, for example, Prescale (registered trademark) manufactured by Fuji Film Corporation.
