Screen output system

A screen output system comprising a first information processing apparatus having a plurality of display outputs and a second information processing apparatus, the first information processing apparatus comprising:

• an image acquiring unit configured to acquire a first image for output to a first display;
• a differential region extracting unit configured to extract a differential region between the first image and a second image for output to a second display;
• a designation accepting unit configured to accept a designation of whether a differential region is output to the second display from one or both of the first information processing apparatus and the second information processing apparatus over one of a network and an input device of the first information processing apparatus, for each differential region;
• and
• an image output unit configured to incorporate a portion of the first image that corresponds to the differential region for which a designation of output has been accepted into the second image and to output the updated second image to the second display.

A screen output control method for implementation by an information processing apparatus having a plurality of display outputs, the method comprising:

• acquiring, by the information processing apparatus, a first image for output to a first display;
• extracting, by the information processing apparatus, a differential region between the first image and a second image for output to a second display;
• accepting, by the information processing apparatus, a designation of whether a differential region is output to the second display for each differential region;
• and
• incorporating, by the information processing apparatus, a portion of the first image that corresponds to the differential region for which a designation of output has been accepted into the second image in response to a synchronization event and outputting the updated second image to the second display.

A computer program product for realizing an information processing apparatus having a plurality of display outputs, the computer program product comprising:

• a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing causing a computer to function as:
• an image acquiring unit configured to acquire a first image for output to a first display;
• a differential region extracting unit configured to extract a differential region between the first image and a second image for output to a second display;
• a designation accepting unit configured to accept a designation of whether a differential region is output to the second display for each differential region;
• and
• an image output unit configured to incorporate a portion of the first image that corresponds to the differential region for which a designation of output has been accepted into the second image and to output the updated second image to the second display.
