摘要:
A map display apparatus according to the present invention has a control circuit which divides a display screen of a display device into a plurality of regions, and processes a bird's-eye view data for each region and convert them into map image data. The control circuit then prepares vehicle information image data for displaying marks indicating current position and destination of the vehicle. In this step, mark data are prepared so that the mark is displayed at a display position corresponding to the destination when the destination is within a display range, and so that the mark is displayed at a display position that lies in the direction of the destination and is closest to the destination when the destination is not within the display range. Upon completion of preparation of the map image data and vehicle information image data, the control circuit displays these data on the display device, and then detects the current vehicle position again. If the vehicle does not run farther than a predetermined distance, only the display position of the vehicle position mark is changed. If the vehicle runs farther than the predetermined distance, the map image data are updated. In the meantime, grid line information used for bird's-eye view display and planimetric map display is stored in advance in a grid-line information memory. The control unit selects appropriate grid line information, depending upon a screen display mode selected by an operator, so as to display the road map with grid lines superposed thereon.

摘要:
An image reading method for an image recording system which reads an image with an image reader in the form of photoelectric signal conversion devices, converts the resulting analog data into digital data, and prints out the digital data with a printer. One line of image is read a plurality of times by the image reader and the resulting image data are sequentially stored. Even when the image data storing time and a fixed one-line scanning period are different from each other, the image can be read and outputted without changing the quantity of light to be applied to the image reader, i.e., simply by compensating for the difference between the storing time and the fixed scanning time. The compensation is implemented by multiplying one line of data stored by a time ratio of the fixed period to the difference, or adopting all the data inclusive of those associated with the difference, or discarding the data associated with the difference, or adopting only valid data, and then averaging the resulting data by division.

摘要:
A microscope objective lens which, in spite of having a great numerical aperture and a high magnification, can always maintain an excellent imaging performance even if the thickness of a parallel flat plate such as a cover glass disposed between the object surface and the objective lens is greatly varied. The microscope objective lens has, in succession from the object side, a first lens group of positive refractive power for converting the light flux from an object into a convergent light flux, the first lens group having a positive meniscus lens component with its concave surface facing the object side and having a cemented lens component, a second lens group having a cemented lens component of negative refractive power disposed in the convergent light flux, and a third lens group of negative refractive power having a meniscus lens component with its convex surface facing the object side and having a succeeding negative lens component. The second lens group is movable on the optical axis relative to the first and third lens groups to correct deterioration of imaging performance due to variation in thickness of the parallel flat plate.
