    摘要： An image processing apparatus includes an edge-portion detector, an edge-width detector, and a tone correction unit. The edge-portion detector detects a pixel of an edge portion by determining whether or not each of pixels constituting image data which has been input is a pixel which is included in the edge portion. The edge-width detector detects, for the pixel of the edge portion detected by the edge-portion detector, an edge width which is a width of the edge portion. When the edge width detected by the edge-width detector is smaller than a value which is set in advance, the tone correction unit performs tone correction differently in accordance with the detected edge width.

    摘要： In a computer aided design (CAD) system, by distributing managements of a number of concerned parts data to a plurality of work stations (WS), a large scale assembly constructed by a number of parts can be easily designed. There is provided a distributed data CAD system in which a user can easily progress the design of an assembly under distributed circumstances without being aware of the locations of the distributed information. A certain client WS transmits parts numbers to a server WS. The server WS searches a parts construction file by using the parts numbers as keys, thereby obtaining parts construction information and transmitting to the client WS. The client WS checks the parts construction information and when parts shape information exists in a parts shape file connected to its own WS, the client WS searches the file by using the shape names and physical path names as keys, thereby obtaining parts shape information. When the parts shape information exists in a file of another WS, the client WS transmits the shape names and physical path names to such a WS. The WS which has received them searches the parts shape file by using the shape names and physical path names as keys, thereby obtaining the parts shape information and transmitting to the client WS.

    摘要： A system for obtaining an optimum focusing position in an optical disc system. An optical beam is impinged onto a track of an optical disc, and a reflection signal having information regarding an intensity of an optical beam reflected by an optical disc is obtained. A predetermined frequency component, the frequency component being generated by a modulation caused by an existence of a pit on a track of the optical disc in a reflecting signal, is extracted from the reflection signal. Then a focus position in which a maximum intensity of the extracted frequency component is obtained is searched by changing the focus position of the optical beam. Further, the above system is incorporated in a focus servo control system for maintaining an optimum focusing position in an optical disc system during reading and writing operations, to determine an optimum offset value which is to be adjusted to compensate an error arisen from a construction of the focus servo control system, during an offset adjusting operation.
