    摘要: A color image editing apparatus capable of improving color detecting accuracy, color-converting a chromatic color into a neutral (achromatic) color and vice verse and performing a hue conversion, while maintaining gradation. The color image editing apparatus in which image signals read out by an image reading unit are converted to density, hue and chroma signals by color display coordinate system convertor to perform a color image editing operation inlcudes a detector for detecting whether or not density, hue and chroma of a detected color image is within predetermined density, hue and chroma ranges, respectively. It is judged by a judging unit whether or not a color of the detected color image is of a predetermined color in responses to an output of the detector, and a color changing unit means converts the density, hue and chroma independently in response to the judgement result of the judging unit.

    摘要: A marker dot detecting device for a color image recording apparatus such as a color copying machine, color facsimile, or color printer. The marker dot detecting device includes a marker dot detecting unit for detecting a marker dot by detecting a plane size of binary image data having a preset marker color. Further, the marker dot detecting unit includes a template mask unit having a first template mask in a predetermined first size and a second template mask in a predetermined second size larger than the first size, the second template mask including the first template mask. The template mask unit outputs a marker dot detecting signal when a detected size of the marker dot is larger than that of the first template mask and smaller than that of the second template mask.
