  • Publication number: 20230083964
    Abstract: Provided are a surface pressure analysis device, a surface pressure analysis method, and a surface pressure analysis program capable of automatically evaluating the surface pressure applied to an inspection surface of a measurement object and supporting an inspector who performs a pass/fail determination of the measurement object. An image acquisition unit (210A) of a server that functions as the surface pressure analysis device acquires an inspection image (10) from a user terminal. The inspection image (10) is a capture image of a pressure measurement sheet that is disposed on the inspection surface of the measurement object and color-developed with a density distribution according to the intensity of the pressure applied to the inspection surface. A conversion unit (222) converts the density value of the inspection image (10) into a two-dimensionally distributed first pressure value.

  • Patent number: 5850887
    Abstract: An acceleration slip control system for a motor vehicle operates so that a request for the upshift of the transmission of the motor vehicle is not output to upshift device in accordance with a road surface condition detected by road-surface condition detection device, on the basis of the detection results of engine revolution-speed detection device and driving-wheel slip detection device, whereby the inferior acceleration of the motor vehicle attributed to the upshift is prevented in order to perform the optimum gear-shift control conforming to the road surface condition.

  • Patent number: 5748335
    Abstract: An image reading apparatus such as a color copying apparatus has a plurality of sensing CCD chips for converting an image of an object into an electrical signal, each sensing CCD chip having a plurality of sensing elements. The apparatus also has a circuit for converting the electrical signal into digital data. A first adjusting circuit is provided for conducting either an operation for obtaining level matching of the electrical signal converted by the sensing chips, or an operation for controlling the gain of the electrical signal converted by the sensing chips.

  • Patent number: 5457753
    Abstract: An image processing device for a negative microfilm reader for easily and precisely designating areas of black frames to be erased. In a microfilm reader having an image reader for reading enlarged projection images of a negative microfilm, an image processor for processing image signals, and a display means for displaying the processed images with black and white reversed, the device comprises area input means for inputting the areas of black frames in the images displayed on the display; and a black frame erasing means for erasing the areas of black frames thus input on the display and outputting the required image with areas of black frame erased.
