Abstract: An image processing method and apparatus extracts outline vectors from a binary image, by defining outline points at positions between white pixel area and black pixel area, closer to the black pixel area, to extract vectors representing the black pixel area smaller than the white pixel area. Outline vector patterns are defined in advance in consideration of the length and the direction of an object vector and the lengths and relative directions of preceding and subsequent vectors. Upon smoothing of the image, outline point after the smoothing are determined in accordance with an outline vector pattern that corresponds to the states of an object vector and its preceding and subsequent vectors in an outline.

Abstract: A method and an apparatus for forming an image by contour vector processing includes scanning a pixel along an edge of the image formed by pixels having a first pixel state and pixels having a second pixel state, discriminating one pixel state of the scanned pixel, and determining the pixel states of pixels bordering the discriminated pixel in the case the discriminated pixel has a first pixel state. Contour vectors are extracted between the discriminated pixel having the first pixel state and pixels having a second pixel state bordering the discriminated pixel which are closer to the discriminated pixel than to the bordering pixels, and outputting the extracted contour vectors to form the image.

Abstract: This invention provides an image processing method and apparatus. According to this invention, contour line data when viewed from a the main scan direction are generated on the basis of the connection relationship between a target line element and adjacent line elements before and after the target line element in one direction of continuous line elements, and a direction of an area to be painted out. It is then set that a pixel position of an odd-numbered contour encountered in a scan operation in the main scan direction indicates a forward rotation position of the area, and that an adjacent pixel position in the main scan direction of an even-numbered contour encountered in the scan operation indicates a reverse rotation position of the area.

Abstract: Outline vectors representing an arrangement of pixels of a binary image obtained by a binary image obtaining unit are extracted by an outline extractor. From the extracted outline vector, isolated points are extracted. These isolated points are stored in an isolated point data generator 7 as information indicative of the position of isolated point. The outline vectors other than the isolated points are stored in the vector generator 3 as vector data. When a binary image is reproduced, the stored position information of the isolated points is developed to produce vector data by the isolated point data developer 8. Accordingly, since the isolated points are stored not in the form of outline vectors, but position information, the storage capacity for storing the outline vectors can be small. This construction is effective in halftone image in particular.

Abstract: Method of ionizing a gas within a chamber having a cathode disposed therein, wherein the sputtering effect upon the cathode is substantially reduced to prolong the life of the cathode. The cathode within the chamber is initially activated to emit thermal electrons by applying a voltage thereto. The gas to be ionized is then introduced into the chamber along with an active gas. Ionization of the gas to be ionized is then achieved by subjecting the gas to be ionized to the thermal electrodes emitted by the cathode. The voltage applied to the cathode and the voltage between the cathode and the wall of the chamber are regulated so as to maintain a substantially constant electric arc current flowing from the wall of the chamber to the cathode.
