Abstract
The invention provides a technique of making color correction by means of a simple operation so that the color difference among imaging apparatus is minimized for a particular color specified by a user. In the color correction operation, an MPU provided in a camera displays a marker on a viewfinder. A user controls a user interface so as to put the marker on a desired color of a color chart thereby selecting a color to be weighted. The MPU inputs data obtained by measuring the color chart via the camera and also inputs color reference data obtained by measuring the same color chart under the same conditions via another camera serving as a reference camera. The MPU determines the coefficients of a linear matrix circuit for making color correction by means of a calculation with a weight specified by the user. The resultant coefficients are set in the linear matrix circuit.
