Abstract: The image forming apparatus includes a color conversion processing unit that has an input profile for color conversion to first image data which is image data of a device-independent color space, and an adjustment target profile for color conversion to second image data which represents gradation values of the plurality of color materials, and a simulation profile for color-converting the second image data to third image data of the device-independent color space, a profile adjustment unit that adjusts the adjustment target profile in accordance with the user input, determines whether or not a color difference before and after the adjustment of the adjustment target profile is smaller than a preset threshold value, and updates the adjustment target profile by using the adjustment target profile after the adjustment when the profile adjustment unit determines that the color difference is smaller than the threshold value, and a color difference calculation unit.

Abstract: A control device acts as a reference color converter that converts inputted image data into reference image data of a color space, a prospective medium color converter that converts the inputted image data into output image data for reproducing the image with a plurality of color materials, and generates comparative output image data of the color space, by converting the color space of the output image data, a color difference calculator that compares colors between the reference image data and the comparative output image data, and calculates a specific color difference corresponding to a predetermined cumulative relative frequency, an image forming cost calculator that calculates the image forming cost, and a sheet selection supporter that extracts the prospective image forming medium that provides the specific color difference smaller than a predetermined threshold, and displays the prospective image forming medium in different appearances according to the image forming cost.

Abstract: An image processing apparatus includes a deformation estimator and a correction processing unit. The deformation estimator estimates a deformation in an image of a subject wearing eyeglasses. The eyeglasses include a pair of lenses in symmetry. The estimation is performed such that when facial contours on both sides are detected inside both the pair of lenses, positions of the detected contours on both sides are used to estimate respective deformations inside both the pair of lenses, and when one of the facial contours is detected inside one of the pair of lenses, a position of the detected one contour is used to estimate deformations inside both the pair of lenses. The correction processing unit calculates correction ratios of images inside both the pair of lenses based on the estimated deformations and uses the calculated correction ratio to correct the images inside the pair of lenses.
