In order to allow a user to arbitrarily set color processing parameters which determine the color reproduction characteristics of a digital camera according to user's preference, an image processing unit obtains color data by performing the same processing as that performed by the digital camera with respect to the sensed data of each color patch included in a color chart by using color processing parameters.

A parameter editing unit edits color processing parameters so as to reduce the color difference between the changed target data and color data. A data input / output unit transmits the edited color processing parameters to the digital camera.

A low cost camera by implementing the major functions in host software is provided. This is accomplished by sending raw, digitized data from the camera directly to the host.

Hence, input data is converted into output data using conversion tables for input and output conversions, which are created for an input or output device and for each conversion setting, and a conversion adjustment table. The conversion adjustment table is modified in correspondence with variations of the color reproduction characteristic of the input or output device or color correction for the input or output device.

Color signals after mapping, which correspond to a gray line of the first image device, are converted into gray color signals according to white and black indicated by the gamut information of the second image device.
