Abstract:
1. An image processing apparatus comprising: a conversion means to convert a target value of a device-independent color space into a value of a device-dependent color space; a means to create a color chart to adjust the converted value of the device-dependent color space, the color chart including the value of the device-dependent color space corresponding to the target value of the device-independent color space and a plurality of values obtained by changing the value of the device-dependent color space in the device-dependent color space; a printing means to print the created color chart; a selection means to select in the device-independent color space a plurality of measured values, measured from the printed color chart, having a predetermined relationship with the target value of the device-independent color space; a calculation means to convert the plurality of the selected measured values into a plurality of values of device-dependent color space and, from the plurality of the converted measured values, calculate a target value of the device-dependent color space corresponding to the target value of the device-independent color space; and an adjustment means to adjust the conversion means based on the calculated target value of the device-dependent color space.
