Abstract: A method for specifying a position through touch input in a screen displayed on a touch panel display. The position is specified by acquiring an initial contact position with the touch panel display, displaying a position displaying cursor in a position according to the initial contact position, displaying the position displaying cursor in the position according to the initial contact position during the period for which the contact position sensing continues until the distance from the initial contact position to the contact position reaches a predetermined distance and terminating the display of the position displaying cursor where the contact position sensing is terminated before the distance reaches the predetermined distance, and displaying the position displaying cursor in such a way that the position displaying cursor follows movement of the contact position after the distance reaches the predetermined distance.

Abstract: An image measuring apparatus is configured such that an image of a measured object placed on a stage is captured by a camera, the captured image is displayed on, a captured image display screen, and determination results based on results of a measurement are displayed in an overview list separately from the captured image of the measured object. The image measuring apparatus includes an individual determination results display region displaying individual determination results for each measurement position; and an overall determination results display region displaying overall determination results for the measured object as a unit. The image measuring apparatus is configured to display the individual determination results and the overall determination results together.

Abstract: An image measuring method performed with an image measuring device measuring a dimension of a measured object from an image of the measured object captured by an image capturer. The method executes a standard reference object measurement measuring a dimension of the standard reference object with the image measuring device; a standard reference dimension input inputting a dimension of the standard reference object specified by a device other than the image measuring device; a preset value calculation calculating a preset value from the dimension of the measured standard reference object and from a dimension of the standard reference object measured by a predetermined measurement tool; a measurement measuring a dimension of a measured object other than the standard reference object using the image measuring device; and a correction correcting the dimension of the measured object other than the standard reference object measured by the image measuring device.

Abstract: When generating a measurement plan for measuring X-ray CT that performs X-ray irradiation while rotating a test object, and in doing so acquires projection image data, reconstructs volume data from the projection image data, and measures a targeted measurement location in the volume data, the present invention calculates required measurement accuracy and a measurement field of view range based on tolerance information included in CAD data of the test object and a measurement location on the test object defined by a measurement operator ahead of time, and automatically generates, from this information, an optimized measurement plan that minimizes the number of measurements.

Abstract: The present invention relates to a position specifying method for specifying a position through touch input in a screen displayed on a touch panel display. The position is specified by the steps of acquiring an initial contact position that is a contact position at the start of sensing of a position where contact is made with the touch panel display, displaying a position displaying cursor in a position according to the initial contact position, displaying the position displaying cursor is the position according to the initial contact position during the period for which the contact position sensing continues until the distance from the initial contact position to the contact position reaches a predetermined distance and terminating the display of the position displaying cursor with no position specifying operation performed in a case where the contact position sensing is terminated before the distance from the initial contact position to the contact position reaches the predetermined distance, and displaying the position displaying cursor in such a way that the position displaying cursor follows movement of the contact position after the distance from the initial contact position to the contact position reaches the predetermined distance so that the relative positional relationship between the position displaying cursor and the contact position at the point of time when the distance from the initial contact position to the contact position reaches the predetermined distance is maintained during the period for which the contact position sensing continues and setting, when position-specifying-operation finalizing operation is sensed after the distance from the initial contact position to the contact position reaches the predetermined distance, the position where the position displaying cursor is displayed when the position-specifying-operation finalizing operation is sensed to be a specified position.

Abstract: A light interference measuring device comprises: a light source 20 that outputs light; a beam splitter 222 that causes the light output from the light source to diverge into a reference optical path and a measurement optical path and that outputs a combined wave in which reflection light that has passed through the reference optical path and reflection light that has passed through a measuring object arranged in the measurement optical path are combined; a reference mirror 231 that is arranged in the reference optical path and that reflects light which is diverged into the reference optical path by the beam splitter 222; a stage 12 that is arranged in the measurement optical path and that has the work W placed thereon; an imaging part 25 that images an image in which the combined wave is formed; a reference mirror adjustment mechanism (234, 238, 239) that adjusts a posture of the reference mirror 231; and a control part that controls the reference mirror adjustment mechanism such that a reflecting surface of the reference mirror 231 corresponds to a measurement surface of the work W, based on an image imaged in a condition where a work W is placed on the stage.
