1. An information processing system comprising:
an imaging apparatus configured to operate in a master mode;
at least one imaging apparatus configured to operate in a slave mode; and
an information processing apparatus,
wherein each imaging apparatus of the imaging apparatus in the master mode and the at least one imaging apparatus in the slave mode is further configured to send a chart image generated by capturing an image of a specific chart to the information processing apparatus, and
wherein the information processing apparatus includes circuitry configured to
calculate a color conversion coefficient in each imaging apparatus in the slave mode based on the chart image generated by the imaging apparatus in the master mode,
send the color conversion coefficient to the imaging apparatus corresponding to the color conversion coefficient, and
perform log conversion based on the color conversion coefficient.
