An image processing apparatus includes an input unit configured to input image data; a generation unit configured to generate image data having undergone color gamut conversion from the image data input by the input unit using a conversion unit configured to convert a color gamut of the image data input by the input unit into a color gamut of a device configured to output the image data; a correction unit configured to correct the conversion unit based on a result of the color gamut conversion; and a control unit configured to control execution of the correction by the correction unit for an object included in the image data input by the input unit.

There are provided an information processing system, an information processing apparatus, an information processing method, an information processing program, an imaging apparatus, a method of controlling the imaging apparatus, and a control program capable of easily performing color matching in a plurality of imaging apparatuses. The information processing system includes: an imaging apparatus that operates in a master mode; at least one imaging apparatus that operates in a slave mode; and an information processing apparatus. Each of the imaging apparatus in the master mode and the imaging apparatus in the slave mode sends a chart image generated by capturing an image of a specific chart to the information processing apparatus, and the information processing apparatus calculates a color conversion coefficient in the imaging apparatus in the slave mode on the basis of the chart image generated by the imaging apparatus in the master mode, and sends the color conversion coefficient to the imaging apparatus corresponding to the color conversion coefficient.
