Patent number: 5570298Abstract: 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.Type: GrantFiled: May 25, 1994Date of Patent: October 29, 1996Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Noriyuki Suzuki, Haruhiko Yokoyama

Patent number: 5568567Abstract: 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.Type: GrantFiled: January 22, 1992Date of Patent: October 22, 1996Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Haruhiko Yokoyama

Image processing method for distinguishing object by determining threshold of image lightness values
Patent number: 5138671Abstract: 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.Type: GrantFiled: November 14, 1990Date of Patent: August 11, 1992Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Haruhiko Yokoyama
