It is possible to compatibly set multiple 'dropout' color ranges and 'non-dropout' color ranges and uniquely determine a dropout boundary. An object of the present invention is to greatly conserve maintenance cost of adding a new dropout form after apparatus operations. A conventional technology aims at assuring relation to a predetermined color region, determining the presence or absence of contention, or uniquely settling a dropout boundary. The present invention provides a means for supplying levels to a &#x201c;dropout&#x201d; color range and a &#x201c;non-dropout&#x201d; color range. A registered color range histogram can be quasi-three-dimensionally visualized so that an operator can make adjustment by viewing a contention determination result and an image.

Disclosed is a rule management apparatus which acquires a design rule for regulating a part shape from systems such as a CAD system, converts the acquired deign rule into data having a hierarchical node format, calculates relationship strength which indicates strength of a relationship between the design rule converted into data having a hierarchical node format and another node, sets to the relationship strength between design rules which are substantially the same but described in different systems to be a maximum value, and stores in an integrating rule DBthe relationship strength and the design rules in association with one another.

In a device and system which perform processing (displaying and outputting) of image data, the amount of data transferred between a memory holding the image data and a processor processing the image data is limited, thereby a great amount of data can be processed at high speed.

An apparatus for calculating a normalized correlation coefficient used as a similarity evaluation measure by using image data values of pixels in a template image and image data values of pixels in a subimage, included in a search image, corresponding to the template image, has a memory that stores image data values of pixels in the search image and calculating means that calculate a sum of image data values of pixels in the template image and a sum of image data values of pixels in the first rectangular region in the search image or a sum of squares of image data values of pixels in the template image and a sum of squares of image data values of pixels in the first rectangular region in the search image. Normalized correlation coefficient calculating means calculate a normalized correlation coefficient on the basis of the sum of image data values of pixels in the template image and the sum of image data values of pixels in the first rectangular region in the search image, or the sum of squares of image data values of pixels in the template image and the sum of squares of image data values of pixels in the first rectangular region in the search image.

A distance measuring technology capable of stably and accurately performing distance measurement of an object without any highly accurate focus control mechanism is provided. A distance measuring apparatus has a mask for restricting light so as to pass through two or more different light passing positions; a lens system for focusing the light passed through the mask; an image taking-in means for taking in images from the light focused by the lens system; and a distance calculating means for calculating a distance from an imaging element to an object using the taken-in images. The mask restricts the light so as to pass through only specified positions.

A distance measuring technology is capable of stably and accurately performing measurement of the distance to the distance to an object without use of a highly accurate focus control mechanism. The distance measurement is performed by an apparatus having a mask for restricting light so as to pass light through two or more different light passing positions; a lens system for focusing the light that has passed through the mask; an image taking-in means for taking in images from the light focused by the lens system; and a distance calculating unit for calculating a distance from an imaging element to an object using the taken-in images. The mask restricts the light so that the light is able to pass through only specified positions.
