Image processing apparatus, terminal device, and non-transitory data recording medium recording control program

A terminal device comprising:

• a photographing device;
• a memory configured to store an instruction;
• and
• a processor configured to execute said instruction,
• said processor being configured to:
• obtain, from another device, an additional image registered in association with a marker image in a photographed image taken by said photographing device, and
• cause a display device to display said photographed image and add said additional image to said photographed image,
• said additional image including a first additional image showing an image in a designated region in a first document, and a second additional image showing a difference between said first document and a second document, said second document being a revision of said first document;
• and
• said processor being further configured to add said first additional image at a position of said marker image in said document in said photographed image and add said second additional image at an area of the difference between said first document and said second document.

A non-transitory recording medium recording a control program for controlling an operation of an image processing apparatus, said control program causing said image processing apparatus to:

• generate a first additional image based on an image in a designated region of a first document,
• generate a second additional image showing a difference between said first document and a second document;
• said second document being a revision of said first document;
• and
• register said first additional image and said second additional image on another device in association with a marker image indicating a revision stage of said first document.

A non-transitory recording medium recording a control program for controlling an operation of a terminal device equipped with a photographing device and an addition device, said control program causing said terminal device to:

• photograph a document using said photographing device,
• obtain, from another device, an additional image registered in association with a marker image in a photographed image taken by said photographing device, and
• display said photographed image and add said additional image to said photographed image,
• said another device storing a first additional image showing an image in a designated region in a first document and a second additional image showing a difference between said first document and a second document, said second document being a revision of said first document in association with a marker image indicating a revision stage for each revised edition of said document,
• said control program further causing said terminal device to:
• determine a revision stage represented by said photographed image based on the marker image in said photographed image,
• obtain said first additional image registered in association with said marker image from said another device, and
• obtain said second additional image from said another device, said second additional image being associated with each of marker images associated with the revision stage represented by said photographed image to a latest revised edition of said first document,
• said displaying including adding said first additional image at a position of said marker image in said document in said photographed image, and adding said second additional image at an area of a difference from the first document.
