Display apparatus, portable information processing apparatus, information recording medium, and electronic apparatus

A display apparatus, comprising:

• displaying means to combine a time axis with a background screen to be three-dimensionally displayed and to display the combined screen on a display screen, a width of said time axis changing to be wider as it approaches a past time and changing to be narrower as it approaches to the future;
• storing means to store background screen data used to display said background screen and time-axis display data used to display said time axis, said storing means having plural types of information of which attributes are different from each other, plural types of attribute information used for identification of types of said plural types of information, plural items of time information related to said plural types of information, and icon information which corresponds to each of said plural types of information and is at least arranged along with said time axis and displayed three-dimensionally;
• and
• controlling means to display-control so as to combine said time axis with said background screen in accordance with said background screen data and said time-axis display data, said controlling means being effective for performing selection of said icon information corresponding to the attribute of each of said plural types of information in accordance with said attribute information, and performing control in accordance with said time information related to plural types of information so that said selected icon information is arrayed to each corresponding time of said time axis;
• wherein said icon information comprises plural items of first icon information which are formed of characters different from each other depending upon the attribute of said plural types of information, and said control means selectively displays one shape of an icon of said plural items of said first icon information.

A display apparatus, comprising:

• displaying means to combine a time axis with a background screen to be three-dimensionally displayed and to display the combined screen on a display screen, a width of said time axis changing to be wider as it approaches a past time and changing to be narrower as it approaches to the future;
• storing means to store background screen data used to display said background screen and time-axis display data used to display said time axis, said storing means having plural types of information of which attributes are different from each other, plural types of attribute information used for identification of types of said plural types of information, plural items of time information related to said plural types of information, and icon information which corresponds to each of said plural types of information and is at least arranged along with said time axis and displayed three-dimensionally;
• controlling means to display-control so as to combine said time axis with said background screen in accordance with said background screen data and said time-axis display data, said controlling means being effective for performing selection of said icon information corresponding to the attribute of each of said plural types of information in accordance with said attribute information, and performing control in accordance with said time information related to plural types of information so that said selected icon information is arrayed to each corresponding time of said time axis;
• and
• operating means to perform operation-inputting of information of said time axis and said icon information that are displayed on said display screen, in which, said plural types of information comprises input information to be operation-input and information regarding time of inputting said input information, and controlling means displays said icon information in accordance with the input-time information;
• wherein said icon information comprises database icon information formed in a past region on said time axis and used to display contents of said database regarding said plural types of information, and said controlling means performs display-control of contents of said database in accordance with an operation-input to said database icon information from said operating means.

A display apparatus, comprising:

• displaying means to combine a time axis with a background screen to be three-dimensionally displayed and to display the combined screen on a display screen, a width of said time axis changing to be wider as it approaches a past time and changing to be narrower as it approaches to the future;
• storing means to store background screen data used to display said background screen and time-axis display data used to display said time axis, said storing means having plural types of information of which attributes are different from each other, plural types of attribute information used for identification of types of said plural types of information, plural items of time information related to said plural types of information, and icon information which corresponds to each of said plural types of information and is at least arranged along with said time axis and displayed three-dimensionally;
• controlling means to display-control so as to combine said time axis with said background screen in accordance with said background screen data and said time-axis display data, said controlling means being effective for performing selection of said icon information corresponding to the attribute of each of said plural types of information in accordance with said attribute information, and performing control in accordance with said time information related to plural types of information so that said selected icon information is arrayed to each corresponding time of said time axis;
• and
• operating means to perform operation-inputting of information of said time axis and said icon information that are displayed on said display screen, in which said plural types of information comprises input information to be operation-input and information regarding time of inputting said input information, and controlling means displays said icon information in accordance with the input-time information;
• wherein said icon information comprises a read-E-mail icon formed in a future region on the said time axis and used to read-display contents of contents of said E-mail, and said controlling means performs display-control of contents of said E-mail in accordance with an operation-input to said read-E-mail icon information from said operating means.

An information recording medium that stores at least information used to generate a display screen, said information comprising:

• background screen data to display a three-dimensional background screen;
• time-axis display, data used to display a time axis that changes in shape so that it is wider at a past time and it becomes narrower as it approaches a future time on said background screen;
• information used to perform display-control in accordance with said background screen data and said time-axis display data so that said time axis is combined with said background screen;
• and
• file-size information regarding file sizes;
• wherein said information used to perform display-control is augmented by said file-size information such that said display-control is performed in accordance with said file-size information so that a length-of-icon information for controlling display of an icon changes in a direction perpendicular to said time axis in accordance with said file-size.
