摘要： An image processor in which a high-frequency component of image signals is diminished, and a density value of each of the "diminished" image signals is compared with a first reference value in a first comparator. A first classifier is provided for classifying the image signals into a character image and a tonal image based on a signal output from the first comparator. A length or an area of an image signal classified into the tonal image is measured, and a second comparator is provided for comparing the length or area of a measured image signal measured with a second reference value corresponding to a reference length or a reference area. A second classifier is provided for further classifying an image signal below the second reference value from the second comparator into an image signal of the character image.

摘要： According to a method and apparatus for estimating a halftone image, a unit area is set and shifted by a focusing lens and a photoelectric transducer in a binary image consisting of black and white regions, and the halftone image is estimated on the basis of a ratio of the white regions to the black regions within each unit area. The number of white pixels is counted by an A/D converter. When different unit areas are used, a specific one satisfying predetermined conditions is selected and shifted in the binary image, and prestored image data is read out from RAMs by column and row address generators and calculated to obtain a halftone estimated value within each unit area. The binary image can be thus a Bayer dither image or a digital binary image.

Condenser electric field generating means such as an electrode for generating an electric field to converge the ion flow toward the ion transmissive aperture of the ion modulating electrode is mounted on the common electrode of the ion modulating electrode at its inlet so that the ion flow of the ion generator using the corona wire may be highly dense.
