Abstract

PURPOSE:To have the preparation of image samples in combining hair style or the like by providing a switching circuit changing over the polarity of a deflecting current of a television camera to a picture combining device to double the kinds of composite images. CONSTITUTION:A portrait is picked up by the 1st camera 1, a card 4 of a hair style is picked up by the 2nd camera 3 and superimposed on the 1st portrait while controlling the position, size of the hair style or hair color by a picture combining device 2. The connection between a horizontal deflection coil of the 2nd camera and its drive circuit is made via a switching circuit and since the direction of a current to the deflection coil is inverted by the changeover of the switching circuit, the horizontal scanning direction is inverted also. Thus, the number of the image of the hair style combined onto the portrait picked up by the 1st camera 1 is two to an object 4 and two kinds of the composite images are obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image composition device that extracts a portion of an image of a person or a landscape object from the screen of a television monitor and composites it with other images.

In the conventional image synthesis apparatus, the images to be synthesized are various photographs and pictures taken by a television camera, and the variety of the synthesized image depends on the number of types of photographs and pictures.

The present invention doubles the types of composite images and improves the variety of composite images by inverting the left and right sides of the composite image.
This will be explained in ii1.

FIG. 1 shows a block I of an image synthesis device in an embodiment of the present invention.
-1 diagram. A first camera 1 photographs, for example, a human image, and an image synthesizer 2 separates the synchronization signal from the first camera 1 to match the synchronization of the second camera 3. Furthermore, the second camera 3 photographs the image signal of the second camera 3 and the video signal of the first camera 1.
Insert only the part. Synthesized Shinzuki'? In addition to the TV monitor, monitor the composite status. More specifically (
d Take a picture of a person with the first camera 1 2, then take a picture of the person with the second camera 3
A card 4 of the hairstyle is photographed, and the position, size, or hair color of the hairstyle is controlled by a full image synthesizer 5 and synthesized with the first human image. You can select various hairstyles, freely adjust them, and decide on your favorite hairstyle by simulating it on the TV/video monitor 6. 8 in Figure 1 is a switching circuit that is a feature of the present invention. Figure 2, Figure 3, Figure 4
Click here for details. In FIG. 2, a horizontal deflection coil 6 for controlling horizontal scanning of the second camera 3 and its drive circuit 7 are connected via a switching circuit 8. In other words, the connection to the horizontal deflection coil 6 is connected to terminal a.
When connecting a', b and b', a and b', b and a'
When connected, the horizontal scanning direction can be reversed left and right.

FIG. 3 shows an embodiment of the switching circuit using a mechanical switch. The switch is a non-yawing type with 3 contacts and 2 circuits.

The state shown in the figure is a state in which a and a' and b and b' are connected. By switching, a and b' and b and a' are connected. FIG. 4 shows an example of the configuration of a switching circuit using switching elements. 9, 10, 11, and 12 are switching elements. c and d are control signal input terminals of the switching element. By sending an on signal to d and an off signal to C, a
/ and a, , b' and b become conductive. d off signal,
Sending an on signal to C, 'from a' and b,
b' and a become electrically conductive.

The horizontal scanning direction of the camera is reversed by reversing the direction of the current in the deflection coil by switching the above-described switching circuit 8. As a result, the left and right sides of the subject (hairstyle) 4 are reversed on the screen of the monitor 5.

Therefore, the image to be combined with the image taken by the first camera 1 is ・1
．． There are two images for one subject 4, resulting in two types of composite images.

As described above, by providing the image synthesis device with a switching circuit that switches the polarity of the deflection current of the television camera, the types of images to be synthesized can be doubled, and the preparation of images to be synthesized, such as hairstyles, can be halved. I can do it.
