Image processing method, image processing program, image processing apparatus, imaging apparatus, imaging method, and imaging program

An imaging apparatus, comprising:

• an imaging section configured to capture light from a subject and output an image signal;
• a white balance adjustment section configured to adjust white balance based on the image signal output from the imaging section;
• a color temperature change instruction section configured to provide instructions for changing the adjusted white balance in a color temperature direction;
• and
• a color temperature change section configured to change, in response to instructions from the color temperature change instruction section, the white balance in the color temperature direction by using values such that each of first and second color signals, which are based on the image signal output from the imaging section, is converted into a logarithm,
• wherein the color temperature change section changes the white balance in a chromaticity deviation direction by using a straight line perpendicular to blackbody radiation that is made linear by converting each of the first and second color signals into a logarithm.
