    摘要: A vertical interpolation circuit interpolates an interpolated pixel with pixels located on upper and lower vertical positions, and outputs a vertical interpolated value. An oblique averaging part averages pixels obliquely located with respect to the interpolated pixel on the basis of an oblique edge angle signal, and outputs the result of calculation as an oblique average. An oblique difference absolute value operation part calculates the absolute value of the difference between the values of the pixels obliquely located with respect to the interpolated pixel on the basis of the oblique edge angle signal, and outputs the result of calculation as an oblique difference absolute value. A mixing part outputs the vertical interpolated value, the oblique average or a mixed value thereof as an interpolated pixel value on the basis of the oblique difference absolute value.

    摘要: A video display monitor, such as a plasma monitor, which uses a subfield method which overlaps weighted multiple binary video images in a time base for display. The stable driving of a plasma display panel may be assured and display in the 256 grey-level may be maintained although vertical synchronizing frequency of the input video signal changes. A vertical synchronizing measurement unit measures the vertical synchronizing frequency of the video signal, and a subfield number adjustment unit adjusts the number of subfields in accordance with a measured vertical synchronizing frequency. The stable driving of the plasma display panel and display in grey levels may be assured by selecting a ROM table with an output bit width equivalent to the number of subfields to be output from multiple ROM tables used for converting the number of bits in the input signal.

    摘要: A wiring pattern inspection apparatus for inspecting an abnormality of a wiring pattern formed on a printed circuit board, which is equipped with an optical image pickup device for optically illuminating a surface of the printed circuit board including the wiring pattern to photoelectrically convert optical information of the printed circuit board surface due to the optical illumination into a grey level image. This grey level image is converted into a bi-level image which separates the grey level image into the wiring pattern side and a background side of the wiring pattern. Thereafter, the bi-level image is once contracted by a first size and then expanded by a second size so as to eliminate a micro conductive portion left on the printed circuit board or a micro pinhole which can be disregarded in the abnormality inspection, thereby preventing the excessive detection.

    摘要: A cylindrical interpolation system for machining a cylindrical surface of a cylindrical workpiece, wherein a tool diameter correcting means (104) obtains a tool center path by calculating a tool diameter offset vector for a machining shape specified with reference to an assumed orthogonal coordinate system, and an interpolating means (107) interpolates the tool center path and outputs an interpolation pulse (PCyi) related to an assumed linear axis and an interpolation pulse (PZi) related to a cylindrical axis. To effect a reverse conversion from the assumed orthogonal coordinate system to the cylindrical coordinate system, a pulse converting means (108) converts the interpolation pulse (PCyi) into an interpolation pulse (PCi) for rotating the rotary axis. A block-start correction component calculating means (105) and synchronous correction component calculating means (109) calculate correction components (Vcy, .DELTA.Vcy), and these correction components (Vcy, .DELTA.Vcy) are interpolated by a block-start correction component interpolating means (106) and synchronous correction component interpolating means (110), and added to the interpolation pulse (PCi) for rotating the rotary axis. As a result, the tool cutting surface can be always located immediately above the axis of rotation of the workpiece, and the side surface being machined is at a right angle to the cylindrical surface of the workpiece.

    摘要: A system is provided for carrying out a reference point return in a numerical control device. A deceleration dog (31) is arranged at a machine table (1) and includes a reference point (4). A deceleration limit switch (2) is operated when in contact with the deceleration dog (31), to generate a first deceleration signal (DEC1). A portion of the deceleration dog (31) from an end thereof with which the deceleration limit switch (2) first comes into contact to a predetermined distance therefrom is used as a hypothetical dog. A deceleration signal generating means generates a second deceleration signal (DEC1) when the deceleration limit switch (2) is in contact with the hypothetical dog. A reference point return processing means carries out a reference point return based on the first and second deceleration signals (DEC1, DEC2). Accordingly, an adjustment of the deceleration dog becomes unnecessary, and the assembling and maintenance are made easy.
