Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a VTR-integrated camera body having a built-in memory for a titler in which video and audio information is stored, and the information can be called by a wireless remote controller as needed. , About usability.

[0002]

2. Description of the Related Art A VTR integrated type camera has a so-called superimpose function or a titler function for superimposing a screen and a character different from the image on a captured image and outputting the superimposed image. This is to superimpose a character signal generated by a character generator (hereinafter referred to as CG), for example, a video signal or a character signal on a photographed video and record or reproduce the video together. An on-screen display (hereinafter referred to as OSD) that puts the title of the photographed content, displays the date and time on the screen, and displays the counter corresponds to this. Next, these functions will be briefly described.

First, the output video signal is clamped at a constant DC potential. Next, the pictographic signal pulse generated by CG and the above-mentioned video signal are added by the character signal adding circuit. As a result, only the part to which the pulse of the pictogram is added is replaced with a constant brightness such as white or black so that it looks like a letter or a picture. Furthermore, if you want to add color to those letters and pictures, only in the pictogram pulse part,
The primary color signals such as red and blue may be superimposed and output. In addition to this, a method of converting chroma signals into color difference signals and adding them,
A method of adding in the state of RGB signals is also used.

The position where the pictogram and the character are displayed on the screen can be arbitrarily determined, but in the case of the title of the photographed content, it is large at the center of the screen, and the date and time are displayed at the corners of the screen. In many cases.

In recent years, there are some types in which pictograms to be inserted when a title is inserted are stored in a read-only memory IC (hereinafter referred to as a ROM) to mix various characters and pictograms.

[0006] As an example of the present invention, as a document describing superimposing, "Transistor Technology" issued by CQ Publishing Co., Ltd., 90-December issue (P.54).

SUMMARY OF THE INVENTION An object of the present invention is to enable the title insertion function described in the above-mentioned conventional example to be remotely controlled by using a wireless remote controller or the like, and
The operability of the integrated camera is improved. Also,
As a result, the number of switches on the camera body can be reduced,
In addition to being able to reduce the size and weight of the main unit, it also has the effects of simplifying operations and reducing product costs.

[0008]

In order to achieve the above object, the title display function and the OSD function, which are conventionally performed by the operation switch in the camera body, can be remotely operated by a wireless remote controller or the like. A ROM (hereinafter referred to as ROM Titler) in which pictograms for displaying titles (hereinafter referred to as title characters) are stored in the camera section or the main body of the deck section, and the necessary character characters can be displayed on the wireless remote controller. The corresponding voice and music can be called at the same time.

[0009]

The IC for ROM titler is built in the VTR integrated camera body. This ROM titler IC has
Characters and patterns associated with annual events and ceremonial occasions are stored in memory. Further, voices and music according to those title characters are also stored together. The wireless remote control for the Titler can be inserted and operated remotely. The pictograms and sounds of the output title can be recorded on the tape if necessary.
It can be put out even when playing a recorded tape. This allows you to add a title when dubbing or editing.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 shows a state in which a title insertion operation is performed by remote control using the wireless remote control 1 for titler. The key panel of the wireless remote controller 1 is categorized into content related to annual events and ceremonial occasions. For example, a case where a title related to New Year's Day is to be given will be described. First, Titler ON / O
Press the FF switching button 2 to enter the title output state. Next, when the "New Year" key 3 is pressed, the picture, characters, music, etc. related to it are called from the ROM Titler IC 9 in the VTR integrated camera body and appear on the shooting screen. The contents of the output screen are confirmed on the output screen of the viewfinder 7 or the monitor TV 20. The titles related to "New Year's Day" are divided into several types and stored in memory, and can be selected by scroll buttons 4 and 5. Similarly, several title screens and sounds can be freely selected for each genre.

FIG. 2 is a block diagram of the circuit operation of the present invention. A wireless remote control 1 transmits a titler switching signal, and the receiver 8 in the camera body receives the signal. From the received signal, RO
Only one set of the title character and the voice stored in the M Titler IC 9 is called and sent to the title adding circuit 10. Camera unit 11 or VTR
The video signal output from the section 12 is the video processing circuit 1
The signal processing is performed by 3 and the title adding circuit 1
At 0, it is added to the title signal and output on the monitor screen.

Further, FIG. 3 shows the part of the title addition circuit divided into a video system and an audio system. The video signal sent from the camera unit is the video signal processing circuit 13,
Entered in. The audio signal sent from the microphone is input to the audio signal circuit 14. The image system is
In the video addition circuit 15, the audio information is mixed with the title character signal, and for the audio system, the audio information stored in the ROM-IC is demodulated into an audible audio signal by the audio demodulation circuit 16, and the audio addition circuit 17 is used. To be mixed.
The video and audio signals mixed with the Titler signal are output to the monitor television 20 and the viewfinder via the output circuits 18 and 19, respectively.

[0014]

The effect of the present invention is obtained when a user wants to put a title suddenly while shooting with a VTR integrated camera, or when he / she wants to put a title at a position where the camera body and the photographer are apart from each other. , It can be done easily and quickly with just one hand. For example, when shooting with a compact VTR integrated camera, by holding the main body with one hand and operating the title remote control with the other hand,
The desired title can be instantly issued and the operability can be improved.
