Abstract: An image forming control apparatus includes: a gradation correction curve generator and a calibration data generator. The gradation correction curve generator generates a gradation correction curve based on a correspondence between an output instruction values each representing a density of an image to be formed by an image forming apparatus and actual density values each representing a density of the image formed by the image forming apparatus. The gradation correction curve represents a correspondence between predetermined standard density values and the output instruction values. When an output instruction value corresponding to a maximum standard density value is smaller than a maximum output instruction value, the calibration data generator corrects the gradation correction curve so that the output instruction value corresponding to the maximum standard density value coincides with the maximum output instruction value, and generates the calibration data based on the corrected gradation correction curve.

Abstract: An image processing apparatus for simulating a print output of a printing machine. The image processing apparatus firstly acquires color value information for converting color value information of image data so that a color reproduced on one surface of a recording medium by the printing machine based on the color value information is reproduced as an output. The image processing apparatus secondly acquires show-through color profile information for converting the color value information so that the color reproduced on the one surface by the printing machine as seen from the other surface is reproduced. The image processing apparatus then generates image data formed by composing first image data obtained by converting the color value information based on the color profile information, with second image data obtained by converting the color value information based on the show-through color profile information and by inverting the converted color value information horizontally or vertically.

Abstract: A sound generating toy capable of generating sound without any power supply and while being simplified in structure, as well as exhibiting more reality. The toy includes a toy body including a head, in which a mouth (4), a door member (5) pivotally moved when the mouth is charged with a toy food (3), a spiral spring wind-up mechanism (6) actuated in association with the door member, a spiral spring unit (7) and a sound output unit (A) are arranged. When an eccentric rotating member (15) mounted on an output shaft (14) of the spiral spring unit is rotated to engage with a sound generating means (8), the sound generating means cyclically generates sound.
