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.

Position specifying method and program

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 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 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.

An image measuring apparatus includes an imager that acquires an image of a measurement target object, a touch panel display that displays the image acquired by the imager and accepts touch input operation of specifying a position in the displayed image, and an edge detector that searches for and detects an edge present in a predetermined range around the in-image specified position specified by a user's touch input operation in the image displayed on the touch panel display. When edges are found in a vicinity of the specified position, the edge detector causes a control object for selecting each of the edges to be displayed on the touch panel display not only in an aspect that prevents a wrong edge from being selected through the touch operation but in an aspect that allows visual recognition of a correspondence between each of the edges and a corresponding control object.

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.

A distance in a scanning direction between a first set of edges which face each other and exhibit an opposite change between light and dark is measured by an image measuring machine, and a bias correction value is calculated based on a difference between a measured value and a true value. Using the bias correction value, detection point correction values, which are correction values in various directions of edge detection points detected by a scan of a measured object using the image measuring machine, are calculated; a correction amount used in correction of the edge detection points is specified based on the detection point correction value in each direction; and the edge detection points are corrected using the correction amount.

Light interference measuring device and program therefor

A machine vision system program editing environment includes near real time context generation. Rather than requiring execution of all preceding instructions of a part program in order to generate a realistic context for subsequent edits, surrogate data operations using previously saved data replace execution of certain sets of instructions. The surrogate data may be saved during the actual execution of operations that are recorded in a part program. An edit mode of execution substitutes that data as a surrogate for executing the operations that would otherwise generate that data. Significant time savings may be achieved for context generation, such that editing occurs within an operating context which may be repeatedly refreshed for accuracy in near real time. This supports convenient program modification by relatively unskilled users, using the native user interface of the machine vision system, rather than difficult to use text-based or graphical object-based editing environments.
