PROGRAM CREATING APPARATUS AND IMAGE CONTROL SYSTEM
In a program creating system, an image that implements prescribed behavior on the screen of an image display unit is drawn with a drawing tool, and with an FBD drawing tool, by handling the image drawn with the drawing tool in the form of an object and connecting a signal line for implementing the behavior to the object, the behavior that the image implements is defined, and the processing flow for the image to implement the defined behavior is described with an FBD language. Accordingly, it is possible to easily create a program that realizes highly representative image display.
1 . A program creating apparatus for creating a program causing a computer to execute processing for controlling an image displayed on a screen of an image display device, comprising:
a drawing unit for drawing an image that implements prescribed behavior on the screen of the image display device; and
a processing describing unit for defining the behavior that the image implements, by handling the image drawn by the drawing unit as an object and connecting a signal line to the object to make the object implement the behavior, and for describing a processing flow for the image to implement the defined behavior with a function block diagram language.
2 . A program creating apparatus according to claim 1 , wherein
the image drawn with the drawing unit has information representing the image as the object; and
the processing describing unit describes the processing flow for implementing the behavior of the image with the function block diagram via the information.
3 . A program creating apparatus according to claim 2 , wherein, when a new behavior is defined for the image by the processing describing unit, a parameter for implementing the behavior is inserted in the information, and the information is stored in the image display device.
4 . An image control system comprising:
an image display device that stores attributes of an image drawn by a drawing unit and information representing behavior that the image implements; and
a computing device that stores a program describing, with a function block diagram language, a processing flow for the image represented by the information to implement the behavior represented by the information,
wherein the computing device executes processing represented by the program, and
the image display device displays the image in such a manner as to implement the behavior represented by the information based on details of the processing performed by the computing device.
