DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for displaying an image including a picture-in-picture screen of a video information recording / reproducing system for recording / reproducing video information.

[0002]

2. Description of the Related Art In recent years, disk recording media such as optical disks and magnetic disks have remarkably increased in capacity and speed.
Regarding optical discs, DVD (Digital Versatile Diode)
sk) as a recording medium of the same standard as DVD-Video, a single-sided 2.6 [G
B] or DVD capable of recording 4.7 [GB] information
-RAM, DVD-RW which can record 4.7 [GB] information on a phase change optical disk, and the like have been commercialized. An optical disk device using such an optical disk as a recording medium has been established as a recording / reproducing device constituting a video information recording / reproducing system which can convert a recording medium and records / reproduces video information requiring a large recording capacity.
The number of magnetic hard disk drives (HDDs) is 10-3.
It has a large capacity of 0 [GB] and a high transfer rate of 100 [Mbps], and is used as a fixed recording / reproducing device constituting the video information system. Further, a hybrid type video information recording / reproducing system including both an optical disk device and a magnetic hard disk device has been realized.

In such a video information recording / reproducing system, recording and reproduction of video information can be performed at the same time, and each of a main screen and a picture-in-picture screen (small screen) can be used by using a display device constituting the system. In addition, a recorded image and a reproduced image can be simultaneously displayed.

FIG. 16 is a configuration diagram of a conventional video information recording / reproducing system, which is described in, for example, Japanese Patent Application Laid-Open No. 11-205670. The video information recording / reproducing system of FIG. 16 includes an editing device that changes the size and position of a picture-in-picture screen. In FIG.
Is a computer, 202 is a hybrid recorder composed of a hard disk array and a VTR for backing up the hard disk array, and 203 is an RS
-422 communication cable, 204: SDI (Serial Digital Interface) for applying a predetermined special effect to the video signal V3
This is a format video effect device (effector).

The computer 201 has a main body 2 having a CPU, a processing circuit, a flexible disk drive, and the like.
01a, a monitor 201b connected to the main body 201a,
It comprises a keyboard 201c and a mouse 201d, a dedicated controller 201e used for setting a reproduction speed, and a flexible disk 201f. The computer 201 has an application program for editing video data installed in a hard disk drive in advance, and operates as an editing device by operating the application program under an operating system. Note that this application program includes a GUI (graphical user interface) for generating a control command in an editing operation.
A graphic image for the GUI is displayed on b.

The operation of the editing apparatus of the video information recording / reproducing system shown in FIG. 16 will be described below. A composite video signal V1 captured by a video camera or the like is
The data is input to the hybrid recorder 202 and is sequentially recorded. The video signal V2 output through the hybrid recorder 202 as it is is input to the main body 201a of the computer 201. The main body 201a
A reduced screen corresponding to the video signal V2 is generated and displayed on the monitor 201b. Hybrid recorder 202
Encodes an input video signal V1 in real time and records it on a hard disk array and a VTR.

[0007] An operator operating the computer 201 monitors the video signal V2 displayed on the monitor 201b while watching the mouse 201d connected to the computer 201.
By operating a pointing device such as
An edit point is specified, and a control command for editing is generated using a GUI displayed on the monitor 201b. This control command is transmitted to the hybrid recorder 202 and the video effect device 20 as an RS-422 control command.
4 is transmitted. Thus, the hybrid recorder 2
02 is controlled, and the reproduced video signal V3
After a predetermined effect such as wipe, mix, mosaic, or picture-in-picture is applied as necessary by the video effect device 204, the video effect is supplied to the computer 201 as a video signal V6 and displayed on the monitor 201b. It is sent to the outside as a video signal V5.
Thus, the mouse 201d while watching the monitor 201b
By operating a pointing device such as the like and performing editing work, an image of the video signal V6 is displayed, for example, using the video signal V2 as a picture-in-picture screen.

FIG. 17 is a diagram of a picture-in-picture screen area setting screen in the editing device of the video information recording / reproducing system of FIG. In FIG. 17, reference numeral 205 denotes a parent screen; 206, a picture-in-picture screen (child screen);
06BAR is a bar (screen area setting bar) that defines the screen area of the picture-in-picture screen 206, 206BAR
-C is the corner of the bar 206BAR, 206BAR-L is the side of the bar 206BAR, and 206I is the inside of the picture-in-picture screen 206 (the inside of the bar 206BAR).

The procedure for changing the size and position of the picture-in-picture screen 206 will be described below. First, when the user sets predetermined settings such as the display coordinates of the picture-in-picture screen on the GUI screen displayed on the monitor 201b, the video effect device 204 sets the picture-in-picture screen 206 on which the screen area setting bar 206BAR is overlaid as the parent. It is displayed at a predetermined position on the screen 205.

Next, it waits until the picture-in-picture screen 206 is dragged by a pointing device such as the mouse 201d.
It is determined whether the bar corner 206BAR-C has been dragged, the bar side 206BAR-L has been dragged, or the bar interior 206BAR-R has been dragged.
When the bar corner 206BAR-C is dragged, the coordinates of the dragged cursor are calculated, and the size of the picture-in-picture screen 206 is changed according to the calculation result. When the bar side 206BAR-L is dragged, the width of the picture-in-picture screen 206 is changed according to the calculation result of the coordinates of the dragged cursor. When the inside 206I of the bar is dragged, the picture-in-picture screen 206 is moved according to the calculation result of the coordinates of the dragged cursor. In addition, what was dragged is bar corner 206BA.
RC, bar side 208 BAR-L, bar interior 206
If none of I, do nothing.

[0011]

However, in the above-mentioned conventional video information recording / reproducing system, in order to change the size and position of the picture-in-picture screen, a pointing device such as a mouse is operated to change the size of the picture-in-picture screen. While looking at the cursor position, the screen area setting bar 206
Since the BAR or the inside 206I must be dragged, it is difficult for the user to easily and freely change the size and position of the picture-in-picture screen, and there is a problem in operability.

The present invention has been made to solve such a conventional problem, and a display apparatus of a video information recording / reproducing system capable of freely and easily changing the size and position of a picture-in-picture screen. The purpose is to provide.
