1-11. (canceled)
A display apparatus comprising:
- storage means for storing a control program having a plurality of instructions and each symbol data for displaying a symbol related to each of said plurality of instructions;
- control means for controlling control target equipment electrically connected to said display apparatus by executing each of said plurality of instructions;
- display means for displaying an image;
- first display control means based on the symbol data corresponding to the instruction executed by said control means for causing the symbol corresponding to said executed instruction to be displayed in a first display region in said display means;
- video signal input means for receiving an input of video data generated based on a picked-up image of said control target equipment;
- video data storing means for storing said video data;
- relation means for relating the symbol data corresponding to the instruction executed by said control means to the video data stored in said video data storing means;
- detection means for detecting designation of the symbol displayed in said first display region;
- and
- second display control means responsive to detection of said designation for causing a moving image to be displayed in a second display region in said display means based on the video data related to the symbol data corresponding to the symbol displayed in said first display region.
A program product causing a computer to function as a display apparatus, said program product causing said computer to execute the steps of:
- reading a control program having a plurality of instructions and each symbol data for displaying a symbol related to each of said plurality of instructions from storage means for storing data;
- controlling control target equipment electrically connected to said computer by executing each of said plurality of instructions;
- based on the symbol data corresponding to the instruction executed at said controlling step, causing the symbol corresponding to said executed instruction to be displayed in a first display region in display means for displaying an image;
- receiving an input of video data generated based on a picked-up image of said control target equipment;
- relating the symbol data corresponding to said executed instruction to said video data;
- storing said video data in said storage means;
- detecting designation of the symbol displayed in said first display means;
- and
- in response to detection of said designation, causing a moving image to be displayed in a second display region in said display means based on the video data related to the symbol data corresponding to the symbol displayed in said first display region.
