Remote instruction system, remote instruction method, and program product therefor

A remote instruction method comprising:

• overlay-displaying a first still frame image of a target taken in a display area of application software, the first still frame image having been captured from a video signal;
• displaying an edited still frame image in the display area by use of the application software;
• extracting the edited still frame image displayed according to a difference between displayed still frame images prior to and subsequent to a generation of the edited still frame image;
• forming an annotation image from the edited still frame image extracted to project the annotation image onto an image-taken area according to an instruction given on the basis of a taken image;
• and
• storing image capturing information, including at least an overlay-displaying position of the captured first still frame image in the display area and information from the display area from which the first still frame image is to be captured,
• wherein forming the annotation image includes the use of a plurality of kinds of the application software executed in parallel.

A non-transitory computer readable medium storing a program causing a computer to execute a process for a remote instruction, the process comprising:

• overlay-displaying a first still frame image of a target taken in a display area of application software, the first still frame image having been captured from a video signal;
• displaying an edited still frame image in the display area by use of the application software;
• extracting the edited still frame image displayed according to a difference between displayed still frame images prior to and subsequent to a generation of the edited still image;
• forming an annotation image from the edited still frame image extracted to project the annotation image onto an image-taken area according to an instruction given on the basis of a taken image;
• and
• storing image capturing information, including at least an overlay-displaying position of the captured first still frame image in the display area and information from the display area from which the first still frame image is to be captured,
• wherein forming the annotation image includes the use of a plurality of kinds of the application software executed in parallel.

A remote instruction system comprising:

• an annotation forming portion that:
• overlay-displays a first still frame image of a target taken by an image taking portion, in a display area of application software, the image taking portion having captured the first still frame image from a video signal, the application software being commonly used software executable on a computer that has a display screen on which an editing window is displayed and that has a drawing function;
• displays an edited still frame image in the display area by use of the application software;
• extracts the edited still frame image displayed according to a difference between displayed images prior to and subsequent to a generation of the edited still frame image;
• and
• forms an annotation image from the edited still frame image extracted to project the annotation image onto an image-taken area of the image taking portion by a projecting portion according to an instruction given on the basis of a taken image, and
• a layout information memory portion that stores image capturing information, including at least an overlay-displaying position of the captured first still frame image in the display area of the application software and information from the display area from which the first still frame image is to be captured.
