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.

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.

Surface texture measuring machine and a surface texture measuring method

Within a prioritized mode selection dialog, either a measurement accuracy prioritized mode or a measurement speed prioritized mode is selected. If the measurement accuracy prioritized mode is selected, then processing for entering a tolerable amount of movement is executed. Then, a relative movement speed of a CCD camera to a measurement stage is calculated from the entered amount of movement. Finally, image information is captured at a lower speed than the calculated relative movement speed to execute image measurement. If the measurement speed prioritized mode is selected, then processing for entering a relative movement speed is executed, and image information is captured at the entered relative movement speed to execute image measurement.

An image measuring method comprises making no stop of an imaging means relative to a measurement stage at measurement positions (MP-MP), and capturing instantaneous images to acquire information required for measurement. A first direction to a measurement position (MP) to be measured next and a second direction from the measurement position (MP) to a next measurement position (MP) form an angle therebetween. If this angle exceeds a certain angle, an overshoot path is formed at a location beyond the measurement position (MP) in the first direction. The larger the angle formed between the first direction and the second direction, the lower the measurement speed at the measurement position (MP) is made.
