Abstract: In an image processing device having an image processing unit, a first determination process determines whether each of the plurality of blocks is a single-color block, a non-single-color block, or a non-determinative block. Determination of the non-determinative block is made when neither a single block condition nor a non-single-block condition is met. A second determination process determines whether the non-determinative block is the single block or the non-single block based on a result of the first determination process with respect to a neighboring block neighboring the non-determinative block. The blank determination process determines whether the image is a blank image based on at least one of number of single color blocks determined in the first determination process or the second determination process and number of non-single-color blocks determined in the first determination process or the second determination process.

Abstract: An image processor includes an identifying unit, a first correcting unit, and a second correcting unit. The identifying unit identifies a white point value of an image represented by first image data. The white point value indicates a first color temperature. The first correcting unit performs a white balance correction on the first image data such that the white point value approaches a target white point value. The target white point value indicates a second color temperature. The second correcting unit performs a brightness correction for correcting the first image data corrected by the first correcting unit into second image data such that an image corresponding to the second image data is brighter as the second color temperature is higher than the first color temperature and such that the image corresponding to the second image data is darker as the second color temperature is lower than the first color temperature.

Abstract: An image-processor includes an acquiring unit and a correcting unit. The acquiring unit acquires image data and ambient light data indicating a degree of a first color temperature with respect to a second color temperature. The first color temperature represents a color temperature for a first ambient light. The second color temperature represents a color temperature for a second ambient light. A first image, which corresponds to the image data, is perceived in the first ambient light as an image having one color appearance. The first image is perceived in the second ambient light as an image having another color appearance. The correcting unit corrects the image data such that a color appearance of the first image under the first ambient light are reproduced under the second ambient light.

Abstract: An image-processing system for printing an image based on original image data. The storing unit stores at least one look-up table in association with at least one printing condition. The at least one look-up table is used to convert a color value in original image data into a limited color value that limits a total quantity of ink to be used in printing. The detecting unit detects, as a printing condition, at least one of a type of color material and a type of recording medium which are used for printing operation. The converting unit converts the color value data into the limited color value by using a look-up table that is assigned with a printing condition corresponding to the detected printing condition.

A correcting unit corrects the first pixel data such that a third color-appearance of a pixel according to the corrected first pixel data under the second ambient light is perceived as a color-appearance that is the same as a fourth color-appearance of a pixel according to the first pixel data under the first ambient light.
