A second memory 4 is a digital memory that inputs and stores the output of the A/D converter 2 when the television camera 1 photographs the hairstyle.

A third memory 5 is a digital memory that stores the video signal of the hairstyle transferred from the second memory 4, and further stores the video signal of the person transferred from the first memory 3 in the background part. It is. Video signals are synthesized in the third memory 5.

Reference numeral 6 denotes an A/D converter, which inputs video signals read out from the first memory 3, second memory 4, and third memory 5, converts them into analogs, and outputs them.

7 is a television receiver, which inputs the output of the A/D converter 6 and displays images.

Reference numeral 8 denotes an operation switch circuit, which is a circuit consisting of a known switch capable of selecting a person recording mode, selecting a hairstyle recording mode, adjusting the size and position of the image, and performing a compositing operation. The operation switch circuit 8 outputs operation signals based on these operations.

9 is a microcomputer in which a program for controlling this hairstyle selection device is written. Microcomputer 9
inputs an operation signal by adjusting the size and position of the image in the operation switch circuit 8 and outputs the image signal of the person stored in the first memory 3 and the hairstyle of the person stored in the second memory 4. A program for specifying an address when storing a video signal in the third memory 5 is written.

The operation will be explained below based on the above-mentioned configuration. FIG. 2 is a flow diagram showing the operation of this hairstyle selection device. When the person recording mode is selected in the operation switch circuit 8 and a person recording operation is performed (step S1), the television camera 1 photographs the person and outputs an analog video signal of the person. This video signal is input to the A/D converter 2, digitized, output, and stored in the first memory 3 (step S2). Next, when the hairstyle recording mode is selected in the operation switch circuit 8 and a hairstyle recording operation is performed (step S3), the television camera 1 photographs the hairstyle and outputs an analog video signal of the hairstyle. This video signal is input to the A/D converter 2, digitized and output, and the second
(step S4).

When a compositing operation is performed in the operation switch circuit 8 (step S5), the video signal of the hairstyle in the second memory 4 is transferred to the third memory 5 and stored therein (step S6). Next, the image signal of the person in the first memory 3 is transferred to the background portion of the image signal of the hairstyle in the third memory 5 and stored (step S7). Further, the combined video signal of the hairstyle and the person is read out, inputted to the A/D converter 6, converted into an analog signal, and inputted to the television receiver 7 for display (step S8).

On the display on the television receiver 7, it is determined whether the size and position of the image of the person and the hairstyle match (step S9). If they match, it means that the compositing is complete; if they do not, the operation is completed. An operation is performed on the switch circuit 8 to adjust the size and position of the image (step S10).

When an operation signal to be output by adjusting the size and position of the image of the person and the image of the hairstyle is input, the microcomputer 9 transfers the image signal of the hairstyle in the second memory 4 to the third memory 5 and the image of the hairstyle to the first memory 5. memory 3
When transferring the video signal of the person in the image to the background part of the video signal of the hairstyle in the third memory 5, addresses are specified so that the size and position of these images match, and steps are performed according to the address designation. S6,S
7 and S8 are repeated. If the size and position of the image of the person and the image of the hairstyle match (step S9), it means that the synthesis is complete; if they do not match, the operation of adjusting the size and position is repeated.

As mentioned above, this hairstyle selection device stores a video signal of a person in a first memory, a video signal of a hairstyle in a second memory, and further synthesizes these video signals in a third memory and outputs the video signal to a television receiver. It is configured to match the size and position of the image on the composite image displayed in 7. Therefore, the contents of the second memory will not be destroyed even if you adjust the size and position of the image, so you can reshoot the hairstyle or import the video signal from external memory each time you compose the image. You won't need it anymore. Therefore, according to this invention, this hairstyle selection device has the unique effect of being easy to operate.
