Information display apparatus, information display method, and storage medium storing program for displaying information

摘要

An information display method, includes inputting a designated point in each of the series of image data items of the image file, which is sequentially designated as the analysis target point by a user's manipulation, every time each of the series of image data items of the image file is sequentially displayed on the display screen, displaying each of the series of designated points, which are sequentially input, at each input position, sequentially displaying each of the series of image data items stored in the designated image file along with each of the series of designated points while each of the series of designated points is displayed, and displaying a designated point after a change in a display mode different from that of a designated point before the change, every time a transition direction of each of the series of designated points changes.

主权项

1. An information display apparatus comprising:
an image file storage unit which stores an image file including a series of image data items each containing an analysis target point of a moving object; a subsequent image display control unit which, when an image corresponding to one of the series of image data items of the image file is displayed on a display screen and a specified position in the displayed image is specified based on an input by a user to correspond to the analysis target point in the image, displays a subsequent image corresponding to a subsequent one of the series of image data items on the display screen; a specified direction determination unit which, each time a subsequent image is displayed by the subsequent image display control unit and another specified position is specified in the subsequent image based on an input by a user, determines a transition direction from a previously specified position to a presently specified position; a direction-change determination unit which determines whether or not there is a change between a current transition direction and a previous transition direction determined by the specified direction determination unit; a direction-change frequency update unit which updates direction-change frequency data indicating a direction-change frequency when the direction-change determination unit determines the change; a specified position display mode control unit which sets a display mode for each specified position and which, each time the transition direction determined by the specified direction determination unit changes, changes the display mode such that a specified position that was specified after the change has a different display mode from a display mode of a specified position that was specified before the change, wherein each display mode uses a number corresponding to the direction-change frequency; a graph display control unit which displays a graph representing movement between a plurality of specified positions that have been specified in images corresponding to the series of image data items of the image file, such that each of the specified positions is displayed in the display mode set for the specified position by the specified position display mode control unit; and a changed number display control unit which sets the display mode for a specified position such that a number corresponding to the direction-change frequency is displayed in a shape which is predetermined as a shape for the number.
