Abstract: When an accessory switch of a vehicle is turned on, a TFT display device in an instrument panel is in a magnified display mode, where a navigation image is displayed in a magnified area of a navigation display area with no meter images displayed. A driver is therefore allowed to attentively view the navigation image in order to perform a route set or to change scales of a displayed map. When the driver further turns on an ignition switch, the magnified display mode is switched to a normal display mode. In the normal display mode, a meter display area and a vehicle state display area coexist with the navigation display area in the TFT display device; a navigation image is displayed in a normal area of the navigation display area with a meter image, e.g., a speed meter image, and a warning indicator image displayed simultaneously.

Abstract: When an ignition switch is turned on to display an image on a display apparatus, the display apparatus first displays a needle image of meter images and a warning indicator image. Out of the meter images, the display apparatus displays the needle image for a specified time period (e.g., 0.2 seconds), and then displays a dial image. After displaying the dial image for a specified time period, the display apparatus displays a navigation image. The specified time period may be set to 0.5 through 1.0 second, for example, long enough to visually check or recognize display of the meter image and the warning indicator image. Accordingly, it is possible to visually check the meter image and the warning indicator image while the navigation image is not displayed.

Abstract: A display device for a vehicle has a display unit that has a meter display area and a navigation display area. The meter display area displays vehicle operation condition, and the navigation display area displays travel route guidance. When a display color changes in the travel route guidance in the navigation display area, color of the vehicle operation condition in the meter display area is also changed so that the color of the travel route guidance becomes more eye-catching than the vehicle operation condition.

Abstract: A navigation system stores setting record information related to places designated as destination or reached place. The setting record information includes setting frequencies with which corresponding places were designated. A control unit searches a map database for places meeting a keyword inputted by a user and causes a display unit to present the places in the descending order of their corresponding setting frequencies in the stored setting record information. The user then selects as a destination a certain place from the presented places. The control unit stores the selected certain place to update the setting record information. Thus, the names of places meeting the keyword inputted are directly displayed in the descending order of the setting frequency with which they have been designated in the past. Therefore, the user need not perform an operation to hierarchically select a desired place by region or facility name.

Abstract: A map image showing a current position and its surroundings, a route, and an arrow are displayed and superimposed on one another. The arrow has a base indicating the current position and a length indicating a predetermined distance along the route. The arrow has the transparency adjusted to be half transparent to make the map image and route discernible. The arrow moves along with the current position as a vehicle travels on the route. When the route is rectilinear, the shape and length of the arrow do not change. When the route is turned left at an intersection, the arrowhead is turned left after reaching the intersection. Since the arrow is displayed along the route, the arrowhead is disposed on a road to which the vehicle is brought by a left turn made on a road on which the base is disposed.

Abstract: 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.

Abstract: Pieces of feature information in a bi-level image such as a width, a branching point and an ending point of a wiring pattern are detected in a design rule checking section according to a micro inspection to find out pieces of feature information departing from a design rule. Also, feature codes in the bi-level image such as a corner of the wiring pattern are detected in a specific shape detecting section according to a macro inspection. The feature information are compared with pieces of referential feature information pertaining to a non-defective wiring pattern in a first comparing and judging section to judge whether the wiring pattern indicated by the feature information is defective or non-defective. The feature codes are compared with referential feature codes pertaining to a non-defective wiring pattern in a second comparing and judging section to judge whether the wiring pattern indicated by the feature codes is defective or non-defective.

Abstract: A correspondence relation between a structure of a bi-level pattern A and a structure of a bi-level pattern B is statistically learned by use of a learning high-density image. The bi-level pattern A forms a partial region of a low-density character and line image except a screened dot image. The bi-level pattern B forms a corresponding partial region of a desired high-density image. A judgement is made as to whether the low-density image is equal to or different from a screened dot image. Reference pixels are selected from the partial region of the low-density image. The low-density bi-level pattern A is converted into the high-density bi-level pattern B on the basis of a result of the learning by use of the selected reference pixels when the low-density image is different from a screened dot image. A pixel of the low-density image is repeated to convert the low-density image into the high-density image when the low-density image is equal to a screend dot image.

Abstract: A pattern inspection system for inspecting a pattern of a land for a through-hole formed in a printed board. In the system there are included a first illumination device for optically illuminating the printed board, a second illumination device for illuminating the printed board with light modulated at a predetermined period and an image pickup responsive to reflection light and transmission light from the printed board due to the first and second illumination devices to photoelectrically convert the printed board into a gray level image. The gray level image is converted into a bi-level image by a bi-level conversion device and then converted into an edge image by an edge detecting device. The edge image is expanded and contracted by predetermined amounts so as to obtain a through-hole image corresponding to the through-hole. A defect detecting device detects a defect of the pattern of the printed board on the basis of the through-hole image and the bi-level image from the bi-level conversion device.

Abstract: A color correction method applicable to a digital processing type of color copier, whereby a set of color patches of respectively different sample colors is printed using a set of printing data values, the color patches are then scanned and analyzed to obtain color patch input data values by the color copier, and each of all of the possible input color data values that can be produced by the scanner/analyzer section of the color copier is then related to one of the color patch input data values which is closest thereto in a 3-dimensional color space. Each of these possible input color data values is thereby related to an appropriate color printing value, whereby a color correction table can be generated which provides correction accuracy that is independent of non-linearity of color printing characteristics.

Abstract: An image processor for reproducing a continuous tone image such as a photograph in a black-and-white binary dot image (halftone image) has a linear correction section for converting a sampled digital image signal in a predetermined manner controlled by black and white densities of an original, thereby performing linear conversion between the continuous tone image and the halftone image. The image processor also has another correction section for performing profile emphasis to obtain a clear halftone image.

Abstract: The invention relates to a method for processing an image signal such that areas of original image data are sequentially scanned with a scanning window having a size corresponding to M picture elements in units of a predetermined number of picture elements so as to perform halftone display in accordance with black-and-white binary distribution with respect to the signal levels of the picture elements within the scanning window every time the scanning window is moved. The picture elements within the scanning window are assigned an order of preference in accordance with their image signal levels. A sum of the image signal levels of the picture elements within the scanning window is calculated, and A and N of the equation S=C.times.N+A are calculated, where C is a predetermined image signal level (e.g., black level and maximum level), N is an integer, and A is the image signal level falling within the range 0.ltoreq.A<C.
