  • Patent number: 6038335
    Abstract: A flaw detection apparatus detects a flaw formed on an object's surface based on a digital image data indicative of said object's surface as regions which are groups of plural pixels utilizing the image processing technique. An image processor is provided for detecting an extending direction in which each region extends based on a contour line of each region, so that regions extending in the same direction are clustered as one region. The image processor further produces a flaw signal indicating sizes of thus clustered regions.

  • Patent number: 5570298
    Abstract: A dot pattern-examining apparatus examines a dot pattern displayed on a display screen by picking up a two-dimensional image of the display screen and by performing image processing with respect to the dot pattern on the two-dimensional image. An image projection data generating section generates image projection data indicative of a set of density values by accumulating, on a predetermined axis, density values of individual dots of the two-dimensional image of the display screen for each line. Then, a run-length data generating section generates run-length data indicative of a set of combinations of an accumulated density value and a length thereof, based on the image projection data of the two-dimensional image.

  • Patent number: 5568567
    Abstract: Two-dimensional image data of an object is processed to inspect a circular arc configuration of the object. Initially, the two-dimensional image data is subjected to a data extraction process in which image edge points of the circular arc configuration of the object are extracted from the two-dimensional image data. The image edge points are then applied to a process to approximate the circular arc configuration of the object by defining a circle which minimizes a mean value of a fourth power error of the image edge points relative to the circle, the thus defined circle being used to approximate the circular arc configuration of the object.

  • Patent number: 5319720
    Abstract: An appearance inspecting method includes the steps of dividing a recognized image of an object into regions based on two attributes of image points within the image calculating the minimum distance of each point within a target region to a periphery of the target region, and measuring a size of the target region from the maximum of the calculated minimum distances of the points in the target region.

  • Patent number: 5138671
    Abstract: An image processing method distinguishes an object from within an image area by determining a stable threshold value of light intensity values from within the image area. Received light is converted into image data denoting light intensity values of the received light at a plurality of points from within the image area. A bright portion average value denoting an average of the light intensity values which exceed a predetermined threshold and a dark portion average value denoting an average of the light intensity values which are less than the predetermined threshold are calculated. A new threshold is obtained by applying the bright portion average value and the dark portion average value to a predetermined dividing ratio. The object within the image area is distinguished using the new threshold. The method is also applicable to the use of multivalue thresholds.
