PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of taking color balance of an image on the basis of the concept of color constancy. SOLUTION: An image processing section 4 of the image processing apparatus includes a conversion means comprising a 3-stimulus value conversion section 41, a primary conversion section 42, a gain adjustment section 43, and a primary inverse conversion section 44. The conversion means can convert a photographing output value obtained by actually photographing a color chart including chromatic colors under a light source of a different kind of a photographing section of the image processing apparatus into a value in matching with the color of the color chart under a standard light source. The conversion means of the image processing apparatus converts an image signal obtained by photographing of the photographing section to adjust a color balance of an image.
