Data distribution system, data distribution apparatus, data distribution method and recording medium, improving user convenience

A data distribution apparatus for outputting distribution data to be displayed on a display device, comprising:

• an input device receiving coordinate data input corresponding to a designated position of input, in a display area of said display device, and
• a controller configured to control said data distribution apparatus for
• i) outputting first handwritten image data to said display device such that based on the coordinate data of which input is received by said input device, the handwritten image is displayed in the display area of said display device,
• ii) determining whether a partial area in said display area of said display device is designated, based on said first handwritten image data, and
• iii) if it is determined that partial area in the display area of said display device is designated, editing said distribution data to ensure said designated partial area as a handwriting area, and outputs the data to said display device.

A data distribution system, comprising:

• a data distribution apparatus outputting distribution data;
• a projector device projecting the distribution data output from said distribution apparatus to a screen;
• and
• an image pick-up device obtaining an image displayed on said screen;
• wherein
• said data distribution apparatus includes a controller configured to control said distribution apparatus for
• i) extracting, based on an image obtained by picking-up the image displayed on said screen by said image pick-up device, an image handwritten to said screen included in an area projected to said screen,
• ii) determining, based on said extracted handwritten image data written to said screen, whether a partial area of said distribution data projected on said screen is designated, and
• iii) if it is determined that a partial area of said distribution data projected on said screen is designated, editing said distribution data and outputs to said projector device, to ensure said designated partial area as a handwriting area.

A data distribution apparatus outputting distribution data to be projected on a screen to a projector device, comprising:

• a controller configured to control said data distribution apparatus for
• i) extracting, based on an image obtained by picking-up the image displayed on said screen, an image handwritten to said screen included in an area projected to said screen as a first handwritten image,
• ii) determining, based on said extracted first handwritten image data written to said screen, whether a partial area of said distribution data projected on said screen is designated, and
• iii) if it is determined that a partial area of said distribution data projected on said screen is designated, editing said distribution data and outputs to said projector device, to ensure said designated partial area as a handwriting area.

A data distribution method of distributing data to be displayed to a display device, comprising the steps of:

• receiving coordinate data input corresponding to a designated position of input, in a display area of said display device;
• outputting first handwritten image data to said display device such that based on the coordinate data of which input is received, the handwritten image is displayed in the display area of said display device;
• determining whether a partial area in said display area of said display device is designated, based on said first handwritten image data;
• and
• if it is determined at said determining step that partial area in the display area of said display device is designated, editing said distribution data to ensure said designated partial area as a handwriting area, and outputting the data to said display device.

A recording medium recording a data distribution program to be executed by a computer of a data distribution apparatus outputting distribution data to be displayed on a display device,

• said data distribution program causing the computer to execute the steps of:
• receiving coordinate data input corresponding to a designated position of input, in a display area of said display device;
• outputting first handwritten image data to said display device such that based on the coordinate data of which input is received, the handwritten image is displayed in the display area of said display device;
• determining whether a partial area in said display area of said display device is designated, based on said first handwritten image data;
• and
• if it is determined at said determining step that partial area in the display area of said display device is designated, editing said distribution data to ensure said designated partial area as a handwriting area, and outputting the data to said display device.

A data distribution method of distributing data to be projected on a screen to a projector device, comprising the steps of:

• extracting, based on an image obtained by picking-up the image displayed on said screen, an image handwritten to said screen included in an area projected to said screen;
• determining, based on said extracted handwritten image data written to said screen, whether a partial area of said distribution data projected on said screen is designated;
• and
• if it is determined at said determining step that a partial area of said distribution data projected on said screen is designated, editing said distribution data and outputting to said projector device, to ensure said designated partial area as a handwriting area.

A recording medium recording a data distribution program to be executed by a computer of a data distribution apparatus outputting distribution data to be projected on a screen to a projector device,

• said data distribution program causing the computer to execute the steps of:
• extracting, based on an image obtained by picking-up the image displayed on said screen, an image handwritten to said screen included in an area projected to said screen;
• determining, based on said extracted handwritten image data written to said screen, whether a partial area of said distribution data projected on said screen is designated;
• and
• if it is determined at said determining step that a partial area of said distribution data projected on said screen is designated, editing said distribution data and outputting to said projector device, to ensure said designated partial area as a handwriting area.
