Display apparatus, display control method, and portable terminal apparatus, and program

A program causing a computer which controls a display apparatus, to perform the process of:

• turning on an indicator so as to correspond to a transmission operation of image data in another image display apparatus,
• wherein the display apparatus includes
• a display unit that displays a predetermined image;
• a communication unit that performs communication of image data with another image display apparatus;
• and
• an indicator unit that is disposed at at least a part of surroundings of the display unit and includes the indicator which is turned on with predetermined luminance.

A portable terminal apparatus comprising:

• a communication unit that performs transmission of image data with an image display apparatus;
• a display unit that displays an instruction image for instructing a transmission operation of the image data;
• and
• a control unit that changes a turning-on state of an indicator of the image display apparatus so as to correspond to a user's transmission operation of the image data based on the instruction image.

A display apparatus comprising:

• a display unit that displays a predetermined image;
• a communication unit that performs communication of image data with another image display apparatus;
• an indicator unit that is disposed at at least a part of surroundings of the display unit and includes an indicator which is turned on with predetermined luminance;
• and
• a control unit that turns on the indicator during communication of the image data with another image display apparatus,
• wherein the control unit turns on the indicator of the indicator unit only during a predetermined period before or after an indicator of another image display apparatus is turned on only during a predetermined period.

A program causing a computer which controls a display apparatus, to perform the process of:

• turning on an indicator of an indicator unit only during a predetermined period before or after an indicator of another image display apparatus is turned on only during a predetermined period while communication of image data with another image display apparatus is performed,
• wherein the display apparatus includes
• a display unit that displays a predetermined image;
• a communication unit that performs communication of the image data with another image display apparatus;
• and
• an indicator unit that is disposed at at least a part of surroundings of the display unit and includes the indicator which is turned on with predetermined luminance.
