Pressure measurement method, information processing device, and program

An information processing device comprising:

• at least one processor,
• wherein the processor
• acquires a color-developing member image that is a captured image after pressure application of a color-developing member that develops color at a density in accordance with an applied pressure in a case in which the same pressure is applied to the color-developing member and a sensor device that outputs an output value in accordance with the applied pressure,
• acquires time-series data of the output value of the sensor device during a pressure application period, and
• performs a process based on the color-developing member image and the time-series data of the output value of the sensor device, and
• the sensor device is made of a material having a hardness of a pencil hardness of 2H or higher.

A non-transitory computer-readable storage medium storing a program causing at least one processor provided in an information processing device to execute a process comprising:

• acquiring a color-developing member image that is a captured image after pressure application of a color-developing member that develops color at a density in accordance with an applied pressure in a case in which the same pressure is applied to the color-developing member and a sensor device that outputs an output value in accordance with the applied pressure;
• acquiring time-series data of the output value of the sensor device during a pressure application period;
• and
• performing a process based on the color-developing member image and the time-series data of the output value of the sensor device,
• wherein the sensor device is made of a material having a hardness of a pencil hardness of 2H or higher.
