DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / reproducing apparatus for monitoring a time-lapse VTR or the like used as a monitoring apparatus in a bank or a company.

[0002]

2. Description of the Related Art For example, when viewing a monitor screen connected to a conventional monitoring recording / reproducing apparatus, it can be seen that the current time and the recording / reproducing time mode are superimposed on an image inputted from outside somewhere on the screen. . There are the following two methods for setting this character position. FIG. 4 shows an example of these, 18 is a conventional monitoring recording / reproducing apparatus, 9 is 1
This is a camera that captures the flower, which is the subject of No. 3. Reference numeral 17 denotes a monitor, and 19 denotes a character signal of a current time and a recording time mode to be superimposed on 13 flowers which are external images. When the user intends to superimpose characters such as the present time of the flower 13 and the current time 19 of the external video, the user determines the position of the superimposed character by using the conventional monitoring recording / reproducing apparatus 18.
The character position data "display position A", "display position B",
Select and set any one of the four "display position C" and "display position D". For example, if “display position B” is selected, the screen of 17 monitors is “display position B”.
An image in which characters such as the current time of 19 are superimposed on the “upper right” of the image of the three flowers is output. Another method is that the user who operates the conventional monitoring recording / reproducing apparatus moves and adjusts the character position little by little up, down, left and right while looking at the monitor screen, finds the best character position, and performs the monitoring recording / reproducing. This is a method of setting in the data input unit of the device.

[0003]

Recently, the surveillance system has been enhanced, and the use of a four-screen splitting device capable of displaying the images of four cameras as four split images on one monitor screen has been increasing. . However, if the above-described four-screen splitting device is connected to a monitoring recording / reproducing device in which the character position such as the current time in FIG. 4 must be selected from four data, a phenomenon as shown in FIG. 5 occurs. Reference numeral 18 in FIG. 5 denotes a monitoring recording / reproducing device for selecting four character positions.
Reference numerals 4, 15, and 16 denote subjects of the cameras 9, 10, 11, and 12, respectively. 8 is the camera 9, 10, 11, 1
Reference numeral 17 denotes a four-screen splitting device for outputting a four-screen split signal obtained by simultaneously editing each video taken in 2, and 17 a monitor for outputting video. In the conventional monitoring recording / reproducing apparatus configured as described above, the cameras 9, 10, 1
Reference numerals 1 and 12 each take a picture of the subject, and
Output to the screen division device 8. The four-screen splitting device 8
Edits four video signals and outputs them as a four-screen split signal, for example, to the monitoring recording / reproducing device 18 in which the position of the character data to be superimposed on the external video is set to “display position B”. The data is output on the monitor screen at the “display position B” at the “upper right” at the same time as the image divided into four screens. Of the four images, the image of the house of the subject 14 taken by the camera 10 is almost the same as the current time. The image overlaps with the character, and the meaning of shooting with the camera is lost. This phenomenon also occurs when the character position data is selected from "display position A", "display position C", and "display position D". In addition, in the case of the conventional monitoring recording / reproducing apparatus in which the user himself inputs an arbitrary value to the data input unit while watching the monitor screen, and determines the character position, the character position is gradually moved up, down, left, and right. It takes time to make a decision, and the operation is very troublesome. An object of the present invention is to make it easier to set a character position such as the current time to be superimposed on an external video than a conventional recording / reproducing apparatus for monitoring, and to provide a "center" in character position data to divide a monitor into four screens. It is an object of the present invention to provide a monitoring recording / reproducing apparatus which also has the above-mentioned correspondence.

[0004]

In order to solve the above-mentioned problems, a monitoring recording / reproducing apparatus according to the present invention comprises a clock means for counting the current time and date, and a character for outputting data from the clock means as a character signal. Generating means, video superimposing means for superimposing the character signal on the video signal, permission of the superimposing means, an input section for setting data of the superposition position, and judging data from the data input section, And control means for controlling the character generating means, and recording / reproducing means for recording / reproducing the superimposed video signal based on the time information set by the clock means. ], “Upper Right”, “Lower Left”, “Lower Right” and “Center” can be added and toggled with a single switch. Especially when the monitor screen is divided into 4 screens, Simply make it possible to superimpose the character of the current time and the like in the best position in the screen.

[0005]

According to the present invention, the user inputs the permission data for superimposing the character data such as the current time and the character position data to the data input section. Since the character position data can already be selected from among five upper left, upper right, lower left, lower right, and center positions, a four-screen splitting device can be used as the monitoring recording / reproducing device. When connecting and outputting four images at a time on the monitor screen and superimposing character data at the same time, select and input the "center" of the character position data of the present invention into the data input section, and you can easily input four images. The best screen on which character data is superimposed on the center of the image can be obtained.

Recording or reproduction is performed while characters such as the current time are superimposed on the screen in which the image is fitted . First, an initial value of the current time is set by the clock means 2 and counted. The switch data of the data input unit 1 is input to the control means 6.
The main contents are display ON / OFF data of character to be superimposed and character position data. When the display ON / OFF data of the superimposed character, which is one of the SW data, is ON, the control means 6 sends the already set character position data to the character generation means 3. The character position data includes five upper left, upper right, lower left, lower right, and center positions.
There are discrete positions of, and the value can be changed in a toggle with one switch, so that it can be easily selected. In the example of FIG. 2, "center" is selected. The character generating means 3 receives the "center" which is the character position signal to be superimposed, and at the same time receives the time information from the clock means 2 as a character signal. The recording / reproducing means 5 records or reproduces a video image in which the four-divided image signal and the character signal are superimposed on the "center" which is the character position signal. On the screen of the monitor 17, four images divided into four by dividing one screen as shown in FIG. 2 into upper , lower, left and right, respectively, and a center position where the upper , lower, left and right dividing lines intersect.
Location in the output image a character is superimposed current time or the like, a character which four images in very best overlap is small place is simply superimposed to obtain the best image. FIG.
When only three cameras are connected to the monitoring recording / reproducing apparatus of the present invention as described above, if the character position data is set to, for example, "lower right", characters such as the current time do not overlap with any of the three images. The best images are easily obtained.
