Claim Text:
1. An image processing apparatus comprising: a representative value calculation unit that selects a designation area that is an area which is configured from a predetermined number of pixels, from a first image which is configured by using an image signal which is output from a one-chip pixel unit in which pixels corresponding to each color component in multiple color components are regularly arranged on a plane, and that calculates a representative value of each of the color components in the designation area; a class classification unit that performs class classification on the designation area, based on an amount of characteristics that are obtained from a pixel value of the designation area; a coefficient reading unit that reads a coefficient that is stored in advance, based on a result of performing the class classification; a color component conversion unit that sets the pixel value relating to a predetermined pixel within the designation area to be a prediction tap, sets the pixel value of one color component, among the multiple color components, to be a reference, and converts the pixel value of each color component of the prediction tap into a conversion value that is obtained by performing offset using the representative value; and a product and sum calculation unit that sets the conversion value to be a variable and calculates each of the pixel values of a second image which is configured from only the pixels corresponding to each color component in the multiple color components and which is an image different in resolution from the first image, by performing product and sum calculation which uses the coefficient which is read.
