Abstract
A color correction device () including: color set information storage portions () which store color set information inclusive of source colors and reference colors; region selection portions () which select specific source regions from source images picked up by two camerasrespectively; region color decision portions () which decide source region colors as colors representative of the source regions; color set update portions () which update source colors in color sets by using the source region colors; and color correction portions () which calibrate colors in ranges similar to the source colors in the two source images to reference colors by using the color sets. It is possible to eliminate the necessity of holding information of color sets unnecessary for color correction, so that it is possible to reduce the load imposed on calculation and adapt to a change of lighting environment in real time.
