FIELD OF THE INVENTION
The present invention relates to picture display apparatuses, picture display methods, picture display programs, and storage media for displaying a plurality of pictures on a single screen. The invention relates especially to picture display apparatuses, picture display methods, picture display programs, and storage media for displaying a menu through which a user can change a screen arrangement to have a plurality of pictures displayed on a single screen.
BACKGROUND OF THE INVENTION
Recent picture display apparatus, of which a typical example is the television, includes more than one picture source, for example, a tuner and an optical disc drive. The apparatus divides the display screen into areas to display a plurality of pictures simultaneously. The apparatus allows the user to switch between a plurality of display modes (ex. a single and a double screen mode) by pressing a screen switching button on a remote controller or by like operation.
Switching between the single and double screen modes is easily done by, for example, pressing a “Double Screen” button. A problem rises, however, when three or more display modes (ex. a single, a double, and a quadruple screen mode) are involved: sequential switching among these modes using one button is troublesome.
To address the problem, Japanese Unexamined Patent Publication (Tokukai) 2001-69369 (published Mar. 16, 2001) discloses a television receiver displaying a menu in response to a user pressing an “Easy Selection” button, the menu listing a plurality of modes from which a desired mode is selectable.
The method disclosed in the patent has problems that the user is not informed of the current function settings and has to go through complex steps to change the settings.
Specifically, the technology of Tokukai 2001-698369 shows the number of screens displayed next to each other. The user is not informed of the actual layout. This is not user-friendly when a large divided screen appears next to a small divided screen and when a web browser or similar picture of unbound aspect ratio is displayed.
Furthermore, if the divided screen or screens are resized following a change in the number of divided screens displayed next to each other, a divided screen resizing menu needs to be displayed after the selection of the number of divided screens so that the user can make selections about the resizing. This requires the user to make several inputs to switch between display modes, which makes the operation complicating.
SUMMARY OF THE INVENTION
The present invention, conceived to address these problems, has an objective of providing a picture display apparatus, a picture display method, a picture display program, and a storage medium which enable the user to easily switch between pictures displayed in divided screens and resize and rearrange the divided screen(s) in which pictures are displayed.
The picture display apparatus of the present invention, to solve the problems, is characterized in that it includes: a synthesizing section for synthesizing divided screens to display a plurality of pictures on a single screen; a menu display section for displaying a menu in which a list of options is displayed, the options enabling a user to select a change to be made to at least one of a number, shapes, relative sizes, and relative positions of the divided screens and types of the pictures, so that the user can select from the options to switch to a corresponding screen arrangement; a layout display section for displaying an icon indicating a border between the divided screens in association with the options; and a border changing section for updating the divided screens according to a change in position of the border, wherein the layout display section displays the icon indicating a result of the change in position of the border before the border changing section updates the divided screens according to the change in position of the border.
According to the arrangement, a menu is displayed for the user to make a selection so as to change to the screen arrangement according to which a plurality of pictures are displayed on a single screen. In the menu, an icon is displayed which indicates the position of the border between divided screens in which the pictures are displayed. Thereafter, the icon indicates a new position of the border before updating the screen according to a change in position of the border. Thus, the user is informed of what the screen will look like before entering a change of the border.

In addition, the following will describe the present invention in terms of a picture display apparatus with a built-in display apparatus as the display screen. This is by no means intended to be limiting the invention. A touch panel can be used as the output and input sections. Manipulation keys on the main body of the picture display apparatus may be used as the input device.
In addition, the picture displayed on the picture display apparatus may be picture signals received on a broadcast wave or fed from an external input apparatus. Also, the picture may be still image data, text data, HTML or other XML data specifying a data layout, or binary data in any given format.
FIG. 1 is a block diagram schematically showing the functions of various sections of the picture display apparatus (picture display apparatus) 10 of the present embodiment. The picture display apparatus 10 includes a display managing section 22, a receiving section 30, a control section 32, a memory section (change information memory means) 34, a menu changing section (menu changing means) 36, a border changing section (border changing means) 38, a communications section (related information receiving means) 52, a browser section 54, a tuner section (related information receiving means) 56, a synthesizing section (synthesizing means) 58, an output section 59, and an input section 60.
The display managing section 22 further includes a label display section 24, an icon display section (layout display means) 26, and a menu display section (menu display means) 28. The display managing section 22 displays information to the user in the form of a menu, labels, and icons, prompting the user to enter screen arrangement switching inputs.
Hereinafter, a screen shall refer to the entire area, from the upper left to the lower right, of the output section 59. A divided screen on the screen shall refer to one of divided parts into which the screen is divided. Each divided screen displays one picture.
A border shall refer to a dividing line between a divided screen on the screen and another. The user can resize and rearrange the divided screens by moving the border. A screen arrangement, or layout, shall refer to settings for divided screens on the screen. That is, a set of divided screens containing information on the sizes, arrangement, etc. of the divided screens on the screen is termed a screen arrangement, or layout.
Some of the accompanying drawings show the term “double screen,” which indicates that there are two types of divided screens and two types of pictures displayed in the divided screens. “Single screen” indicates that there is one picture and one divided screen. “Double screen & the Internet” indicates that there are three types of divided screens and three types of pictures one of which is a browser display.
The label display section 24 displays, in a label display area 96 of the menu 92, a label which identifies a new layout. In the label display area 96 is displayed information which identifies different layouts by text. The label display area 96 displays an explanation on the content of the screens being displayed: e.g., “TV,” “Double TV Screen,” “TV & the Internet,” “Double Screen & the Internet,” and “the Internet.”
The icon display section 26 displays divided screen layout information in the form of icons in a layout display area 96 in the menu 92. The icons indicate the sizes and layout of the divided screens, such as “TV” and “the Internet,” in association with the label display area 96 so that the user can recognize the divided screen layout and divided screen border positions visually and intuitively.
The menu display section 28 associates the label display area 96 and the layout display area 94, presents a result as options in screen switching to the user, and displays as a menu enabling the user to select a layout switching. Specifically, the menu 92 shows a plurality of options on top of each other, one of the options, for example, consisting of an icon indicating a single divided screen and associated text “TV” next to the icon, so that the user can select one of the options by manipulating up/down keys. Details of the menu 92 with a label display area 96 and a layout display area 94 will be given later.
The receiving section 30 receives user inputs through the input section 60 and feeds them to the control section 32. The receiving section 30 may include an infrared receiver, wireless receiver, optical communications receiver, signal input receiver, or other various receiver depending on the configuration of the transmitting section in the input section 60.
Based on manipulation signal inputs through the receiving section 30, the control section 32 gives the display managing section 22 instructions as to a display, accesses required information in the memory section 34, and instructs the menu changing section 36 to update the display according to results of the user inputs. The memory section 34 is a memory device for holding template information, such as label information, icon information, layout information, and menu information, which the display managing section 22 needs to produce a display. The control section 32 may record/store, in the memory section 34, data which is fed where necessary.
Based on the manipulations inputs fed from the control section 32, the menu changing section 36 gives the menu display section 28 instructions to update the screen display according to the results selected and entered by the user. In addition, the menu changing section 36 feeds the result of the selection by the user to the border changing section 38 so that the section 38 performs layout switching. The border changing section 38 transmits a control signal to the synthesizing section 58 based on the instructions from the menu changing section 36 so that the section 58 performs layout switching.
The communications section 52 connects to an external network over the Internet, for example, to receive various data. Specifically, the communications section 52 receives Web data, email data, etc. The browser section 54 displays what is reproduced from the various data received by the communications section 52. Specifically, the browser section 54 runs a browser, email client, etc. to output what is reproduced from the data received by the communications section 52. The tuner section 56 receives broadcast radio waves and electronic program table data and decodes the received image signals and electronic program table data for output. Specifically, the section 56 selectively receives broadcast signals, such as terrestrial analog broadcasts, terrestrial digital broadcasts, and BS/CS digital broadcast. Here, a digital broadcast receiving tuner is taken as an example for description. This is by no means intended to be limiting the invention.
The synthesizing section (synthesizing means) 58 synthesizes divided screens based on the control signals from the border changing section 38 so that the data image received by the communications section 52, the broadcast picture received by the tuner section 56, etc. can be displayed in the divided screens. Here, the picture outputs from the communications section 52 and the tuner section 56 are synthesized for an on-screen display, as an example. Pictures may be received from an optical disc reader device or any other various picture input sources for output on the divided screen.
The output section 59 is an output device for outputting the display signals from various sections in the display managing section 22 and the screen synthesized by the synthesizing section 58. The section 59 is, for example, an image display element built around liquid crystal, organic EL (Electro Luminescence), etc, or a display device such as a CRT (Cathode Ray Tube). The invention is not limited to any particular types of display devices. The embodiment is described taking as an example the picture display apparatus 10 including a display device as the output section 59. This is by no means intended to be limiting the invention. The picture display apparatus 10 may be that which outputs a plurality of divided screens and a manipulation menu to an external display device for display.
Next, referring to FIG. 2, a flow will be described for displaying a screen by the picture display apparatus 10 in the present embodiment. FIG. 2 is a schematic illustration of a flow of the picture display apparatus 10 producing a display of synthesized pictures from a plurality of sources in divided screens into which the screen is divided.
The input section 60, referring to a remote controller, is an input device enabling the user to enter inputs. The receiving section 30, referring here to an infrared receiving section, is a communications interface for infrared communications with the remote controller.
The control section 32 is a control unit which receives manipulation signals and data from various sections and gives instructions for suitable control, manipulation, recording, and other operations. Here, the section 32 controls various sections to perform various processes based on manipulation information received by the receiving section 30.
Major processes include: the tuner receiving pictures from broadcast stations, the synthesizing section 58 synthesizing from received picture sources and the display section 59 displaying the result in divided screens, the communications section 52 receiving data from a server, the display managing section 22 producing divided screens from received data and data in the memory section and the output section 59 displaying the result, user manipulation for program viewing, browser manipulation, and the memory section 34 recording information on, for example, results of, for example, changes to settings.
The communications section 52, in response to an instruction from the control section 32, accesses a server using the HTTP or another Internet protocol to obtain data. The tuner section 56 receives broadcast waves and feeds to the synthesizing section 58. The communications section 52, in response to an instruction from the control section, accesses a server using the HTTP or another Internet protocol to obtain data.
Next, a flow of event processing in the control section 32 will be described in reference to FIG. 3. FIG. 3 is a schematic illustration of a flow of event processing performed by the picture display apparatus 10 to synthesize, from video sources, the divided screens into which the screen is divided and display a result.
The judging section 70, upon detecting a user manipulation via the receiving section 30, outputs to the control section 32 a manipulation information communicating event indicating the particulars of the manipulation. Specifically, the section 70 determines which key has been pressed and feeds that information to the control section 32. The judging section 70 may identify a particular command input from, for example, button manipulations like keeping a button down for a period, releasing a button after keeping it down for a while, pressing a button repeatedly, and pressing two or more button at the same time, and output the result to the control section 72.
The control section 32 instructs various sections (detailed later) to execute various processes in response to, for example, a key event communicated from the judging section 70, an application event communicated from the browser or other applications, and a timer event communicated from a timer (not shown). The control section 32 manages a state transition table, determining the content of processes from the correspondence between the current state and the received event and controlling various sections to execute the processes.
The browser section 54 is a processing section running a so-called WWW browser. In accordance with the event received from the receiving section 30, the judging section 70, and the control section 32, the section 54 (1) obtains an HTML document, image data, etc. via the communications section, (2) analyzes the received HTML document, (3) makes the synthesizing section display the analyzed HTML document and image data, (4) writes cache data to the memory section, (5) loads bookmarks, proxy information, etc. from the memory section.
The television display section 55 decodes the broadcast wave received from the tuner section 56 and displays a result on the output section 59 via the synthesizing section 58. Since decoding is usually handled by hardware, the picture data may be supplied directly from a television application to the output section 59 for decoding and display, In addition, the television display section 55 adjusts the sound volume and selects a channel in response to a user command.
The program list managing section 57, although we give no particular details about it in the specification, regularly obtains program list information via the tuner section 56. The section 57 also instructs to display the program list information in accordance with a user command.
The menu changing section 36 tracks (1) the current layout, that is, the current number of divided screens and the current position(s) of the divided screen border(s) and (2) instructs the display managing section 22 to display a screen division menu 92, a focus change display in which to determine for which divided screen and video source the inputs are intended, a division position change display in which to change the position of a border and the number of divided screens, etc. in accordance with key event received via the receiving section 30, the judging section 70, and the control section 32.
The display managing section 22 instructs the planes of the output section 59 to draw pictures. The section 22 also manages buffer off screen and on screen.
There may be further provided a function settings managing section (not shown) which handles various menus, for example, color and brightness picture settings, manages the current state, when there is a change command input from the user, update accordingly and saves the settings to the memory section, and instructs the display managing section to display in response to a user manipulation.
Next, referring to FIGS. 4 to 7, an execution flow will be described in response to a video source switching manipulation and a divided screen border changing manipulation on the screen division menu. FIG. 4 is an illustration of the display screen 90 and the screen division menu 92 superimposed on the display screen 90.
