(f) Embodiment FIG. 1 shows a block diagram of the entire karaoke apparatus which is an embodiment of the present invention. In FIG. 1, l is an image signal processing device according to the present invention. The video playback device 4 plays back karaoke software on a laser disc, for example, and supplies the video signal v1 to the image signal processing device l. Further, the video playback device 4 mixes input signals from the microphones 7a and 7b into a playback audio signal, and outputs the mixed signal to the amplifier 8. The amplifier 8 amplifies the audio signal and drives the speakers 9a and 9b.

On the other hand, the video camera 5 photographs the face and figure of the person singing and provides the video signal (2) to the image signal processing device 1.

In the image signal processing device 1, a synthesis device 2 inputs the output signal v1 of the video playback device and the output signal V2 of the video camera 5, performs certain signal processing, and sends the result to a monitor TV 6, which is a video display device. Output. The video printer 3 prints out the composite signal as a still image.

In the figure, reference numeral 10 is a video light for illuminating the subject. Next, examples of contents displayed on a TV monitor or recorded on a video printer are shown in FIGS. 2 and 3. The compositing device 2 shown in FIG. 1 has two modes, an input image mode and a compositing mode, and in the input image mode, the camera image is displayed together with a window as shown in FIG. 2. The outside of the window displays the background color, and a predetermined character string such as the date and store name is displayed in the corner of the screen. In the compositing mode, a camera image is displayed together with a frame in a part of the video playback image as shown in FIG. Also, the date and character string are displayed superimposed on the video playback image.

Next, a block diagram of the synthesis device 2 shown in FIG. 1 is shown in FIG. 4. In Fig. 4, ■1 is a video input signal from a video playback device, V2 is a video input signal from a video camera,
(2) is a video output signal for the monitor TV and video printer. The demodulation circuit 11 demodulates Vl, which is a composite video signal, and outputs R, G, and B color signals or Y (
(luminance) signal, R-'r' color difference signal and iJ'B Y color difference signal. The synchronization separation circuit 12 receives the video input signal V
Extract the synchronization signal from 1. Internal synchronization signal generation circuit 13
generates a synchronization signal that controls the memory read timing, window image signal and character pattern generation timing, etc., which will be described later. The control circuit 14 is an A/D
Controls the converter 15 and controls reading and writing of the memory 16. The A/D converter 15 converts the color signal or the luminance and color difference signals into digital data. The memory 16 stores these data for each pixel. This memory 16 consists of a dual port memory that allows writing and reading from separate ports.

In the figure, the demodulation circuit 17, synchronous separation circuit 18, control circuit 19, A/D converter 20, and memory 21 are replaced by the above-mentioned demodulation circuit 11, synchronous separation circuit 12, control circuit 14, A/D converter 15, and memory 16. The same processing is applied to the video input signal V2 from the video camera.
Do about. However, the control circuit 19 converts the read addresses of the memory 21 and the window generation circuit 22 according to the mote. In other words, in input image mode, memory 2
iQ written data and window generation circuit 2
2 data is synchronized with the internal synchronization signal and the successive addresses are advanced sequentially so that they are displayed on the entire screen,
In the composition mode, the successive addresses of the memory 21 and the window generation circuit 22 are set so that the contents written in the memory 21 and the data of the window generation circuit 22 are displayed on a part of the display screen (the upper right part in the example of FIG. 3). control.

The window generation circuit 22 outputs a window image signal based on the signals (address signal and read signal) from the control circuit 19 based on the written window data. The window data write circuit 23 writes data of a predetermined window pattern to the window generation circuit 22 in accordance with the selection of a window pattern given from the outside. The second window pattern
Several types can be selected, such as an oval shape as shown in the figure and a heart shape as shown in FIG. The window synthesis circuit 24 synthesizes data of the output signal of the memory 21 and the output signal of the window generation circuit 22 to generate a window synthesis image signal in which the camera image is fitted into the window. The character pattern generation circuit 25 generates an image signal of a date and a character string. The character pattern writing circuit 26 writes a character pattern into the character pattern generating circuit 25 based on the date data of the clock circuit 27 and the character string data written in the FROM 28. At this time, the writing position of only the date character pattern is switched depending on the distinction between the input image mode and the composition mode (see the date display position in FIGS. 2 and 3). The data synthesis circuit 29 synthesizes the output data of the memory 16, the output data of the window synthesis circuit 24, and the output data of the character pattern generation circuit 25, respectively, and sequentially outputs the final data of each pixel. At this time, the output data of the memory 16 and the window synthesis circuit 2
Select any of the 4 output data. That is, if it is outside the window, the output data of the memory 16 is selected, and if it is inside the window, the output data of the window synthesis circuit 24 is selected.

Further, if there is an output signal from the character pattern generation circuit 25, the output signal from the character pattern generation circuit 25 is output as is. Further, this data synthesis circuit 29 outputs background color data outside the window in the input image mode (see FIG. 2).

The D/A converter 30 converts the output data of the data synthesis circuit 29 into an analog signal. The modulation circuit 31 modulates each color signal or the luminance signal and the color difference signal again into a composite signal, superimposes a synchronization signal, and outputs a video signal V.

With the above configuration, the direct images reproduced by the video reproducing device are sequentially written into the memory 16, and the images captured by the video camera are sequentially written into the memory 21. In the input image mode, the output image 75 of the character pattern generation circuit 25 is added to the composite image with the memory contents in the memory 21 and the window generation circuit 22, and a display as shown in FIG. and print out. In addition, in the composition mode, a window-composed image, which is the output of the window composition circuit 24, is inserted into a part of the data in the memory 16, and an output image of the character pattern generation circuit 25 is superimposed on it, as shown in FIG. A display and printout as shown will be made.

Note that the display position of the character string and date and the window display position within the screen in the compositing mode can also be made movable horizontally and vertically within the screen.

Furthermore, in the input image mode, the periphery of the window can be blurred by giving the window image data a gradation and switching between the camera image data and the background color using the window image data as a weight.
