DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display control device, a display control method, a storage medium, and shutter glasses.
More specifically, the present invention relates to a display control device and a display control method suitable for displaying a stereoscopic image, a storage medium, and shutter glasses.

2. Description of the Related Art Conventionally, a stereoscopic image display method using shutter glasses has been known. FIG. 8 is a block diagram showing a display system using a personal computer for stereoscopically displaying a set of parallax images according to a conventional example. The display system includes a personal computer (hereinafter abbreviated as PC) 1, a display 12, and liquid crystal shutter glasses 1.
3 and a shuttering signal generator 14. In the PC 1, a parallel interface 3, a CPU 4, a memory 5, a stereoscopic image display control unit 6, a recording device 7, and a display controller 8 including a VRAM 9 are connected to the CPU bus 2. The image output from the PC 1 to the display 12 is performed via the display controller 8.

A pair of left and right parallax images for stereoscopic display is a PC
1, or is input from the parallel interface 3 via an imaging device (not shown). FIG. 8 illustrates a case where an image in the recording device 7 is displayed. First, the recording device 7 in the PC 1
After the set of parallax images loaded from the left and right is transferred to the VRAM 9, the parallax images are displayed on the display 12 alternately side by side. At this time, the stereoscopic image display controller 6 controls
The display controller 8 is controlled so as to switch and display a set of left and right parallax images according to a video signal having a vertical scanning frequency of the order.

On the other hand, the observer observes the image on the display 12 using shutter glasses for switching the left and right shutters in synchronization with the switching of the display of the left and right images. Now, as an example of shutter glasses, liquid crystal shutter glasses 13 using liquid crystal shuttering will be described. The observer can see a stereoscopic image by viewing the right image only with the right eye and the left image only with the left eye among the left and right images displayed on the display 12 through the liquid crystal shutter glasses 13 in a frame-sequential manner.

A shuttering signal of the liquid crystal shutter glasses 13 is generated by a shuttering signal generator 14 connected between the display controller 8 and the display 12 in the PC 1. An identification signal indicating which one of the left and right images to be stereoscopically displayed in advance is the left or right image, for example, Lenny Lipton and Je
ff Halnon “UNIVERSAL ELECT
RONIC STERIOSCOPIC DISPLA
Y "SPIE vol. 2653 pp. 219-223
According to FIG. 9, as shown in FIG. 9, the right image 301 includes a right image identification signal 303 such that the ratio of white to black is 3: 1 at the bottom.
In the left image 302, a left image identification signal 304 having a ratio of white to black of 1: 3 is inserted at the bottom.

Here, when displaying on the display 12, the branched shuttering signal generator 14 identifies left and right identification signals, and generates a shuttering signal according to the identification. The liquid crystal shutter glasses 13 receive the shuttering signal and open and close the shutter.

[0007]

However, in the display system according to the conventional example shown in FIG. 8, it is necessary to provide a separate shuttering signal generator 14 when performing stereoscopic viewing. The shuttering signal generator 14
Had to supply power by itself, which had a problem of high cost.

There is another system in which the shuttering signal generator is not provided externally, and the shuttering signal is generated by software existing on a program memory of a recording apparatus. FIG. 10 is a block diagram of a display system according to another conventional example. The display system includes a personal computer (hereinafter abbreviated as PC) 1,
A display 12, liquid crystal shutter glasses 13, a keyboard 17, and a mouse 19 are provided. In the PC 1, the parallel interface 3 and the CP are connected to the CPU bus 2.

The display system of FIG. 10 performs the same operation as the display system of FIG. However, FIG. 10 differs from FIG. 8 in that the liquid crystal shutter glasses 13 are not connected to the shuttering signal generator 14 outside the PC 1 as in FIG. 2 through the interface 15 for liquid crystal shutter glasses. As a result, a shuttering signal is generated directly from the CPU 4 in the PC 1 by application software, and the liquid crystal shutter opens and closes the left and right shutters of the liquid crystal shutter glasses 13 based on the shuttering signal.

However, in the display system according to the conventional example shown in FIG.

FIG. The program of the present invention is supplied by inserting a storage medium 601 such as a floppy disk or a CD-ROM into a storage medium insertion port 602 provided in the PC 11 constituting the stereoscopic display system. Then, the program is loaded from the storage medium 601 onto the program memory of the recording device 7 as described above, and is executed under the control of the CPU 4.

FIG. 7 is a diagram showing a configuration example of the storage contents of a storage medium 601 storing a program for performing a display control process according to a first embodiment of the present invention and a second embodiment to be described later. is there.

Is displayed.

On the other hand, after displaying the left and right images on the application code, a signal for switching the shutter to the address of the liquid crystal shutter glasses 21 connected to the USB interface 20 is generated. Now, 2 bits are given to the shuttering data, and data is set to "01" when closing only the right-eye shutter and "10" when closing the left-eye shutter. The liquid crystal shutter glasses 21 are set to “0” from the USB interface 20.
A mechanism for shuttering either the right eye or the left eye when a signal of "1" or "10" is received is provided, but the method of giving a command for shuttering is not limited to this example. Absent.

Next, a method of transmitting data by USB in the stereoscopic display system according to the first embodiment will be described. USB communication is performed by passing a token from each device (generally called a function) connected to the USB interface 20, that is, the PC 11 as a host to the function.

FIG. 2 is a schematic diagram of a communication sequence for one frame. This one frame is composed of SOF (Start of F
rame) 501, an isochronous transfer 502, a bulk transfer 503, and an interrupt transfer 504, which are processed every 1 millisecond.

ntifier Field) 702 and EOP (End of P
acket) 703. In the figure, reference numeral 704 denotes ADDR (Func
tion Address Field), 705 is ENDP (Endpoin)
t Field), 706 is a CRC (Cyclic Redundancy C)
heck) 5, 707 is DATA and 708 is CRC16.

When transmitting data via USB, first, an OUT token packet 601 is transmitted. O
The UT token packet 601 is composed of a 7-bit ADDR 704 for giving an address of a peripheral device to be transmitted, and a 4-bit ENDP for giving a destination endpoint number.
705 and a 5-bit CR that performs a check field
C5 706 is included.

Therefore, first, the address of the liquid crystal shutter glasses to be shuttered is substituted into the ADDR field 704 of the OUT token packet 601 and transmitted. Next, a DATA data packet 602 is transmitted.
Here, DAT containing data for 0 to 1024 bytes
A field 707 and check field 16
Bits CRC16 and 708 are provided, and a signal for controlling the shutter of the liquid crystal shutter glasses is substituted in this area. Data is 2 bits of “01” or “10” as described above.
It is.

By transmitting the above packets,
Communication via USB can be performed. For example, if a command for transmitting data 01 to address 0x01h is issued after displaying the left image on the application,
When the left image is displayed on the liquid crystal shutter glasses, the shutter of the right eye is closed, so that only the left eye can see. By performing this alternately on the left and right, the open / close control of the liquid crystal shutter glasses by the application software is controlled by USB.
