    Abstract: In color separation processing by a method that combines a multidimensional LUT and interpolation processing, smooth gradation is implemented by reducing errors accompanying interpolation processing. An image processing apparatus includes a color separation processing unit configured to perform, by interpolation processing using a lookup table having a plurality of dimensions in accordance with signal components of an input image, color separation of an input value that is each pixel value of the input image into an output value corresponding to each of signal components handled by an output device, and each grid point of the lookup table is associated with information representing change characteristics at each portion between adjacent grid points for each dimension of the plurality of dimensions, and in the color separation processing, the interpolation processing is performed based on the information representing the change characteristics.

    Abstract: An image reading device according to the present disclosure includes a support plate, a CCD sensor, an insulating member, a CCD mounting board and an elastic member. The CCD sensor is arranged on one surface of the support plate. The insulating member is arranged on the other surface of the support plate. The elastic member fixes the CCD mounting board to the support plate. The elastic member includes: a main body portion; a first arm and a second arm which are bent with respect to the main body portion and which have a first engagement portion and a second engagement portion that are engaged with the edges of the support plate; and a protrusion portion which is provided in the main body portion and which presses the CCD mounting board toward the support plate. The tip end portion of the first arm is bent at an acute angle.
