BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts and components are denoted by the same reference numerals. Their names and functions are the same. Therefore, detailed description thereof will not be repeated.
[0018]
In the present embodiment, a case where the content display device according to the present invention is realized using a computer will be described.
[0019]
FIG. 1 is a block diagram showing a specific example of a hardware configuration of content display device 100 according to the present embodiment. Referring to FIG. 1, content display device 100 is controlled and operates by a program being executed by CPU (Central Processing Unit) 13.
[0020]
The program executed by the CPU 13 is read from a recording medium such as a CD-ROM 300 by a CD-ROM (Compact Disc-Read Only Memory) drive 15 or supplied through a network 200 via a network I / F 17 to a hard disk. 12 is registered. Alternatively, it may be registered in the hard disk 12 from the beginning. The CPU 13 sequentially reads out the programs registered from the hard disk 12 into the memory 14 and executes them.
[0021]
In addition, the content display device 100 receives an input of an instruction from a user from the input device 11 including a keyboard, a mouse, and the like. Also, the content data is displayed on the display device 16 including a display or the like.
[0022]
Note that the specific example of the hardware configuration shown in FIG. 1 is a specific example of the hardware configuration of a general computer, and the hardware configuration of the content display device according to the present invention is the same as the configuration shown in FIG. It is not limited.
[0023]
Next, FIG. 2 shows a specific example of a functional configuration of the content display device 100 according to the present embodiment. Each unit shown in FIG. 2 functions when CPU 13 executes a program registered in hard disk 12.
[0024]
Referring to FIG. 2, content display device 100 includes control unit 1004, input unit 1007, display unit 1001, content processing unit 1002, content storage unit 1003, memory 1005, and two-dimensional / three-dimensional display time measuring unit 1006. It is comprised including.
[0025]
The control unit 1004 is configured by the CPU 13 and the like, receives an instruction signal from the input unit 1007, executes a program in the memory 1005, and displays a display unit 1001, a content processing unit 1002, a content storage unit 1003, and a two-dimensional / three-dimensional display. A control signal is output to the time measurement unit 1006 to perform these controls.
[0026]
The display unit 1001 includes the above-described display device 16 and the like. The content display device according to the present invention is characterized in that the display unit 1001 can perform two-dimensional display and three-dimensional display, and can instantaneously switch between two-dimensional display and three-dimensional display. .
[0027]
The three-dimensional display on the display unit 1001 is based on the fact that the position of the left eye and the right eye of the human being can be stereoscopically viewed by averaging 6 to 6.5 cm, and for the left eye with a slight difference between the left and right. This is realized by configuring the image and the image for the right eye so as to enter each eye. The difference between the left and right eye images is hereinafter referred to as parallax, and when the parallax decreases to 0, the three-dimensional display shifts to the two-dimensional display. Conversely, as the parallax increases from 0, the two-dimensional display shifts to a three-dimensional display.
[0028]
The content storage unit 1003 stores content data that can be browsed on the display unit 1001. In addition, as necessary, the content storage unit 1003 accesses various servers via the network 200 to download and acquire new content data. Then, the content storage unit 1003 extracts a predetermined content according to the control signal input from the control unit 1004, and outputs the extracted content to the content processing unit 1002.
[0029]
The content processing unit 1002 processes the content data input from the content storage unit 1003 into a form that can be displayed on the display unit 1001, according to the control signal input from the control unit 1004. Then, the content processing unit 1002 outputs the processed content data to the display unit 1001. The display unit 1001 displays the content data input from the content processing unit 1002 according to the control signal input from the control unit 1004.
[0030]
The two-dimensional / three-dimensional display time measurement unit 1006 measures a display time on the display unit 1001 and outputs an elapsed time signal indicating the elapsed time in response to a control signal input from the control unit 1004, which is an inquiry about the elapsed time. Input to the control unit 1004.
[0031]
When the display unit 1001 displays the content data in three dimensions, the control unit 1004 starts the three-dimensional display based on the elapsed time signal input from the two-dimensional / 3-dimensional display time measuring unit 1006. It monitors whether the elapsed time exceeds a preset three-dimensional display time. At the same time, the control unit 1004 also monitors whether or not an instruction signal is input from the input unit 1007 due to the user inputting to stop the three-dimensional display.
[0032]
As a result of monitoring, when the time elapsed from the start of the three-dimensional display exceeds the three-dimensional display time, the control unit 1004 outputs a control signal to the content storage unit 1003 and the content processing unit 1002, and The display unit 1001 outputs the content data in which the parallax of the displayed three-dimensional content is gradually changed. The control unit 1004 outputs a control signal to the display unit 1001 when the transition of the display of the content from the three-dimensional display to the two-dimensional display is completed, and switches the display of the content data to the two-dimensional display state.
[0033]
On the other hand, when the display unit 1001 displays the content data in two dimensions, the control unit 1004 stops the three-dimensional display based on the elapsed time signal input from the two-dimensional / 3-dimensional display time measuring unit 1006. It is monitored whether the time elapsed from the time does not exceed a preset three-dimensional display stop time. At the same time, the control unit 1004 also monitors whether or not an instruction signal is input from the input unit 1007 when the user performs input for performing three-dimensional display.
[0034]
As a result of the monitoring, when the time elapsed from the stop of the three-dimensional display exceeds the three-dimensional display stop time, the control unit 1004 outputs a control signal to the display unit 1001 to display the content data in the three-dimensional display state. Switch to. Subsequently, the control unit 1004 outputs a control signal to the content storage unit 1003 and the content processing unit 1002, and gradually widens the parallax of the currently displayed content to shift to three-dimensional display.
[0035]
Next, the flow of processing in the content display device 100 according to the present embodiment will be described using the flowchart of FIG. The process shown in the flowchart of FIG. 3 is realized by the CPU 13 reading and executing a program registered in the hard disk 12, and causing each unit shown in FIG. 2 to function.
[0036]
Referring to FIG. 2, first, control unit 1004 is a timer counter in two-dimensional / three-dimensional display time measuring unit 1006, and is a switching control time t for performing a two-dimensional to three-dimensional display switching control. _{p (2D} → _3D) Is set to a default switching time (S101), a control signal is output to the content storage unit 1003 and the content processing unit 1002, and the process of switching the content data displayed on the display unit 1001 to three-dimensional display is executed. (S103). At the time of step S103, the content data with a parallax of 0, that is, two-dimensional content data, is displayed on the display unit 1001. Even when the display unit 1001 is capable of three-dimensional display, if the disparity of the displayed content data is 0, the user does not see three-dimensionally but two-dimensionally.
[0037]
Next, the content processing unit 1002 changes the switching control time t set in step S101 according to the control signal input from the control unit 1004. _{p (2D} → _3D) Then, a process for gradually transitioning the content data displayed on the display unit 1001 from two-dimensional to three-dimensional is executed (S105). The transition from the two-dimensional display to the three-dimensional display in step S105 will be described later in detail with reference to a subroutine. In some cases, it is difficult to dynamically change the parallax of the content data like a stereo photograph. For example, when the content data is a stereo photograph, which is two still images photographed by two photographing devices at an appropriate distance, the parallax is determined when the stereo photograph is photographed. When the content data is such a stereo photograph, it is difficult to gradually increase or decrease the parallax of the three-dimensional content. In such a case, it is preferable to cope by reproducing a three-dimensional moving image in which the parallax gradually changes.
[0038]
At the same time, the control unit 1004 is a timer counter in the two-dimensional / three-dimensional display time measuring unit 1006, and the three-dimensional display time timer counter t indicating the measurement result of the time during which the display unit 1001 performs three-dimensional display. _3d And a three-dimensional display stop time timer counter t indicating a measurement result of a time during which three-dimensional display is not performed on the display unit 1001 _no3d Are initialized (S107).
[0039]
Then, the control unit 1004 checks whether the display unit 1001 performs three-dimensional display (S109), and executes a three-dimensional display process (S111) or a non-three-dimensional display process (S113) according to the situation. Is repeated. The three-dimensional display processing in step S111 and the non-three-dimensional display processing in step S113 will be described below further using a subroutine.
[0040]
The three-dimensional display processing in step S111 will be described with reference to the flowchart in FIG.
[0041]
When display unit 1001 is performing three-dimensional display (YES in S109), control unit 1004 outputs three-dimensional display time timer counter t input from two-dimensional / 3-dimensional display time measuring unit 1006. _3d And monitor the three-dimensional display time timer counter t _3d It is monitored whether or not exceeds the preset three-dimensional display time (S201).
[0042]
And a three-dimensional display time timer counter t _3d Exceeds the preset three-dimensional display time (YES in S201), the control unit 1004 is a timer counter in the two-dimensional / three-dimensional display time measuring unit 1006, and controls the display from three-dimensional to two-dimensional. Switching control time t for executing switching control _{p (3D} → _2D) Is set to the default switching time (S207), a control signal is output to the content storage unit 1003 and the content processing unit 1002, and the content data displayed on the display unit 1001 is switched from three-dimensional to two-dimensional. Is executed.
[0043]
Alternatively, a three-dimensional display time timer counter t _3d Is not over the three-dimensional display time, if the instruction signal indicating the instruction to stop the three-dimensional display is input from the input unit 1007 from the user (NO in S201 and YES in S203), the control is performed. The unit 1004 controls the switching control time t in response to the instruction signal indicating the urgency of the user. _{p (3D} → _2D) (S209), outputs a control signal to the content storage unit 1003 and the content processing unit 1002, and switches the content data displayed on the display unit 1001 from three-dimensional to two-dimensional. Is executed. The appropriate switching time according to the degree of urgency according to the user's instruction may be obtained by measuring the force of pressing the button, which is the input device 11, when the user gives the instruction, the speed of pressing the button, and the like. Alternatively, information such as whether the user is strong or weak in three-dimensional display may be registered in advance, and such information may be used. Alternatively, the three-dimensional display time at the time when there is an instruction from the user may be used, or the determination may be made by combining a plurality of these methods.
[0044]
The content processing unit 1002 determines the switching control time t set in step S207 or S209 according to the control signal input from the control unit 1004. _{p (3D} → _2D) Then, a process for gradually transitioning the content data displayed on the display unit 1001 from three-dimensional to two-dimensional is executed (S211). The transition from the three-dimensional display to the two-dimensional display in step S211 will be described later in detail with reference to a subroutine. When it is difficult to dynamically change the parallax of the content data as in a stereo photograph, it is preferable to cope with the situation by reproducing a three-dimensional moving image in which the parallax gradually changes.
[0045]
Next, the control unit 1004 outputs a control signal to the display unit 1001 when the transition processing from the three-dimensional display to the two-dimensional display of the content data in the content processing unit 1002 is completed, and the content in the display unit 1001 is output. The display of the data is switched to the two-dimensional display (S213). Then, the control unit 1004 controls the three-dimensional display time timer counter t. _3d Is initialized (S215), and the process returns to the main routine shown in FIG.
[0046]
The three-dimensional display time timer counter t _3d Does not exceed the three-dimensional display time, and if there is no input of an instruction signal indicating an instruction to stop three-dimensional display from the input unit 1007 (NO in S201 and NO in S203), control The unit 1004 includes a three-dimensional display time timer counter t _3d Is incremented (S205), and the process returns to the main routine shown in FIG.
[0047]
On the other hand, the non-three-dimensional display processing in step S113 will be described with reference to the flowchart in FIG.
[0048]
When the display unit 1001 is not displaying the three-dimensional content data (NO in S109), the control unit 1004 outputs the three-dimensional display stop time timer counter t input from the two-dimensional / three-dimensional display time measuring unit 1006. _no3d And the three-dimensional display stop time timer counter t _no3d Monitor whether or not exceeds a preset three-dimensional display stop time (S301).
[0049]
Then, the three-dimensional display stop time timer counter t _no3d Exceeds the preset three-dimensional display stop time (YES in S301), the control unit 1004 is a timer counter in the two-dimensional / three-dimensional display time measuring unit 1006, and displays from two-dimensional to three-dimensional. Switching control time t for executing the switching control of _{p (2D} → _3D) Is set to the default switching time (S307), a control signal is output to the display unit 1001, and the display on the display unit 1001 is switched from two-dimensional display to three-dimensional display (S311). At this time, the disparity of the content data displayed on the display unit 1001 is 0, and the disparity of the displayed content data is 0 even when the display unit 1001 can display three-dimensional content data. Therefore, it does not look three-dimensional to the user.
[0050]
Alternatively, a three-dimensional display stop time timer counter t _no3d Is not over the three-dimensional display stop time, the control is performed when an instruction signal indicating a three-dimensional display instruction from the user is input from the input unit 1007 (NO in S301 and YES in S303). The unit 1004 controls the switching control time t in response to the instruction signal indicating the urgency of the user. _{p (2D} → _3D) Is set (S309), and a control signal is output to the display unit 1001 to switch the display on the display unit 1001 from two-dimensional display to three-dimensional display (S311). The appropriate switching time according to the degree of urgency according to the user's instruction may be obtained by measuring the force of pressing the button, which is the input device 11 when the user gives an instruction, or the speed of pressing the button. Alternatively, information such as whether the user is strong or weak in three-dimensional display may be registered in advance, and such information may be used. Alternatively, the three-dimensional display time at the time when there is an instruction from the user may be used, or the determination may be made by combining a plurality of these methods.
[0051]
Next, the control unit 1004 outputs a control signal to the content storage unit 1003 and the content processing unit 1002 to execute a process of switching the content data displayed on the display unit 1001 from two-dimensional to three-dimensional. The content processing unit 1002 determines the switching control time t set in step S307 or S309 according to the control signal input from the control unit 1004. _{p (2D} → _3D) Then, a process for gradually transitioning the content data displayed on the display unit 1001 from two-dimensional to three-dimensional is executed (S313). The transition from two-dimensional display to three-dimensional display in step S313 is the same as the process in step S105 described above, and will be described later in detail with reference to a subroutine. When it is difficult to dynamically change the parallax of the content data as in a stereo photograph, it is preferable to cope with the situation by reproducing a three-dimensional moving image in which the parallax gradually changes.
[0052]
Then, at the stage when the transition processing of the content data from the two-dimensional display to the three-dimensional display in the content processing unit 1002 is completed, the controller _no3d Is initialized (S315), and the process returns to the main routine shown in FIG.
[0053]
The three-dimensional display stop time timer counter t _no3d Does not exceed the three-dimensional display stop time, and there is no input of an instruction signal indicating a three-dimensional display instruction from the user via the input unit 1007 (NO in S301 and NO in S303), the control is performed. The unit 1004 includes a three-dimensional display stop time timer counter t _no3d Is incremented (S305), and the process returns to the main routine shown in FIG.
[0054]
Further, in step S105 or S313 described above, a switching process for gradually transitioning the content data displayed on the display unit 1001 from two-dimensional to three-dimensional, and in step S211 the content displayed on the display unit 1001 is performed. A switching process for gradually shifting data from three-dimensional to two-dimensional will be described with reference to the flowcharts of FIGS.
[0055]
Referring to FIG. 6, first, the control unit 1004 sends a control signal to the two-dimensional / three-dimensional display time measuring unit 1006 for the switching process for gradually transitioning the content data from two-dimensional to three-dimensional. Is output, an elapsed time timer counter t for counting the elapsed time is initialized (S401), and the elapsed time from the start of the process is counted.
[0056]
Next, the content processing unit 1002 having received the control signal from the control unit 1004 acquires the elapsed time timer counter t from the two-dimensional / three-dimensional display time measuring unit 1006 via the control unit 1004, and Is the switching control time t set in step S101 or S307 or S309. _{p (2D} → _3D) Is monitored (S403).
[0057]
The elapsed time timer counter t is equal to the switching control time t _{p (2D} → _3D) Does not exceed (NO in S403), the content processing unit 1002 inputs, from the content storage unit 1003, a process of expanding the disparity currently set in the content data displayed on the display unit 1001 by a predetermined ratio. The process is executed for the content data thus obtained (S405).
[0058]
Upon completion of the processing in step S405, the content processing unit 1002 increments the elapsed time timer counter t (S407), and determines whether the elapsed time timer counter t has reached the switching control time t. _{p (2D} → _3D) Is reached (YES in S403), the processes in steps S405 and S407 are repeated.
[0059]
Then, the elapsed time timer counter t indicates the switching control time t. _{p (2D} → _3D) Is reached (YES in S403), the switching process ends, and the process returns to the main routine.
[0060]
Referring to FIG. 7, first, the control unit 1004 sends a two-dimensional / three-dimensional display time measurement unit 1006 to the two-dimensional / three-dimensional display time measurement unit 1006 for switching processing for gradually transitioning the content data from three-dimensional to two-dimensional. The control signal is output, the elapsed time timer counter t for counting the elapsed time is initialized (S501), and the elapsed time from the start of the process is counted.
[0061]
Next, the content processing unit 1002 having received the control signal from the control unit 1004 acquires the elapsed time timer counter t from the two-dimensional / three-dimensional display time measuring unit 1006 via the control unit 1004, and Is the switching control time t set in step S207 or S209. _{p (3D} → _2D) Is monitored (S503).
[0062]
The elapsed time timer counter t is equal to the switching control time t _{p (3D} → _2D) Is not exceeded (NO in S503), the content processing unit 1002 inputs, from the content storage unit 1003, a process of narrowing the parallax currently set to the content data displayed on the display unit 1001 by a predetermined ratio. The process is executed for the content data thus obtained (S505).
[0063]
When the processing of step S505 is completed, the content processing unit 1002 increments the elapsed time timer counter t (S507), and the elapsed time timer counter t increases the switching control time t. _{p (3D} → _2D) Is reached (YES in S503), the processing in steps S505 and 507 is repeated.
[0064]
Then, the elapsed time timer counter t indicates the switching control time t. _{p (3D} → _2D) Is reached (YES in S503), the switching process ends, and the process returns to the main routine.
[0065]
When the content display device 100 of the present embodiment executes the above-described processing, the transition of the content data from the three-dimensional display to the two-dimensional display and the transition from the two-dimensional display to the three-dimensional display on the display unit 1001 can be performed. This is performed as shown in FIGS. FIG. 8 is a diagram showing the relationship between the display state and the parallax when the display of the content data shifts from three-dimensional to two-dimensional. FIG. 9 shows the relationship when the display of the content data shifts from two-dimensional to three-dimensional. FIG. 4 is a diagram illustrating a relationship between a display state and parallax.
[0066]
That is, the content display device 100 according to the present embodiment executes the above-described processing to switch the display of the content data from three-dimensional to two-dimensional, as shown in FIG. The display dimension on the display unit 1001 is switched to two-dimensional display at (the timing when the parallax is 0). That is, the parallax of the content data is gradually narrowed while the display state of the display unit 1001 remains the three-dimensional display, and the display is gradually shifted from the three-dimensional display to the two-dimensional display.
[0067]
When the display of the content data is switched from two-dimensional to three-dimensional, as shown in FIG. 9, the display dimension on the display unit 1001 is changed to three-dimensional display at the timing when the display is switched from two-dimensional to three-dimensional. Switch. That is, first, the display state on the display unit 1001 is switched to three-dimensional display, and then the parallax of the content data is gradually widened, and the display is gradually shifted from two-dimensional display to three-dimensional display.
[0068]
In FIG. 9, transition from two-dimensional to three-dimensional due to the elapse of parallax with time is shown by a linear graph. Alternatively, a non-linear transition may be performed.
[0069]
By doing so, in the content display device of the present invention, when the content data displayed on the display unit is switched from three-dimensional display to two-dimensional display, the three-dimensional display shown in FIG. After the intermediate display as shown, the display is gradually switched to the two-dimensional display shown in FIG. Conversely, when the content data displayed on the display unit is switched from the two-dimensional display to the three-dimensional display, the content data is switched from the two-dimensional display shown in FIG. 12 to the intermediate display shown in FIG.
