    摘要: It is an object of the present invention to improve the compression ratio of a color image and to clearly display the outlines of characters and the like. A hue cluster classifying/unifying unit reduces the number of hue values of each pixel in a color image, based on a hue histogram, allocates the number-reduced hue value to each pixel and classifies pixels with the same hue value into one cluster. Furthermore, the unit unifies clusters whose hue values are below a predetermined value. The unit also traces the outline of a cluster whose size is below a reference value and determines that a cluster that has a lot of change points belongs to a character area. An encoding unit determines the characteristic of each cluster, based on both an area determined by an area determining unit and whether the cluster belongs to a ruled line area or a character area, and encodes pixels in each cluster by a coding method suitable for the characteristic of the cluster.

    摘要: An edge detecting method detects edge segments by searching all of the search lines forming an image from an end of the image in a direction perpendicular to the edges. If a line whose edge segment cannot be detected exists, a search is made in all of the search lines from the vicinity of the center of the image toward the end of the image, whereby edge segments are detected. A linear edge is determined from edge segments. A plurality of edge candidates are obtained from the edge segments for all of the search lines, and an optimum candidate is selected from among the edge candidates. Ruled lines are extracted from the source document in the image, and an optimum candidate is selected based on a comparison with a ruled line. As a result, an edge of the source document can be detected with high accuracy even if an image on a background side is unstable, or if materials of the background and the source document are similar.

    摘要: In an authentication apparatus, an input section acquires a living body image which an image capture apparatus generates by capturing an image of a living body that is an object of authentication, and outputs the living body image to an operation section. When the operation section acquires the living body image from the input section, the operation section calculates, on the basis of the living body image acquired and a registered image stored in a registered image storage section, the difference between the relative position of the living body with respect to the image capture apparatus at the time of acquiring the living body image and the relative position of the living body with respect to the image capture apparatus at the time of acquiring the registered image. The output section outputs guidance information for prompting a reduction in the difference in the relative position calculated by the operation section.

    摘要: A chromatographic separator characterized in that two pumps are employed for controlling chromatographic separation that combines a first process for supplying at least one of feed solution and eluent into a circulation system and extracting the same quantity as that of liquid supplied into the circulation system from one position of a packed column where some component is enriched in the circulation system, and a second process for circulating liquid in the system without supplying the feed solution and eluent and extracting the separated component at all. Easy-to-control chromatographic separator, in which a total number of pumps to be used is decreased and high separation performance is attained through a simple structure, can thereby be provided.
