Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hairstyle selection device used to select in advance the hairstyle of a subject's hair. The subject's hair is photographed, the video signals from the respective television cameras are mixed, and the hair of the subject is replaced with the hairstyle of a hairstyle model and reproduced on a monitor, and the hair of the reproduced image is configured to be replaceable with various hairstyle models. The present invention relates to a hairstyle selection device that facilitates the selection of a subject's hairstyle.

An embodiment of the hairstyle selection device of the present invention will be described below with reference to the drawings.A first television camera 1 photographs the subject's head, and a second television camera 2 adjusts the brightness level to the hair 100 portion and the other back 11 portions. The hairstyle models 12 with a sufficiently large difference are photographed, the video signal 13 from the output terminal of the first television camera 1 is applied to the first gate circuit 3, and the video signal from the output terminal of the second television camera 2 is taken. signal 1
4 is applied to the second gate circuit 4 and also to the geeing pulse generation circuit 5.

A synchronizing signal 15.16 is applied from the synchronizing signal generating circuit 6 to the first and second television cameras 1 and 2, so that the first and second television cameras 1 and 2 perform synchronous scanning.

The second television camera 2 is further provided with a deflection current adjustment circuit 7 so that the image of the hairstyle model 12 can be freely adjusted vertically or horizontally depending on the shape of the subject's face.

The deflection current adjustment circuit 7 increases the vertical deflection current applied to the second television camera 2 by the deflection current adjustment circuit 1, and when it is expanded in the vertical direction, the image of the hairstyle model 12 is expanded in the vertical direction by the expansion rate. Conversely, when the vertical deflection current applied to the second television camera 2 is reduced and the image of the hairstyle model 12 is reduced in the vertical direction, the image of the hairstyle model 12 is expanded in the vertical direction by the reduction rate.

Reduction and expansion in the horizontal direction can also be performed in the same manner as described above.

If the horizontal and vertical deflections are simultaneously expanded or contracted by the same ratio, the image of the hairstyle model can be expanded or expanded in the same shape, but only in size.

The keying pulse generation circuit 5 converts the video signal 14 from the second television camera 2, which is represented by the depressed area 17 of the hair 100 part of the hairstyle model 12 as shown in FIG. The keying pulse 19 corresponding to the hair 9 of the hairstyle model 12 as shown in FIG. 2b is generated.

At this time, the pulse 20 corresponding to the blanking period of the video signal 14 is removed.

Two keying pulses 21 and 22 having opposite phases are derived from the output terminal of the keying pulse generation circuit 5, and one of the keying pulses 21 is applied to the first gate circuit 3, and the keying pulse 21 is applied to the output terminal of the first gate circuit 3. A video signal 24 from which a signal portion corresponding to the hair 23 of the subject is extracted is derived, and the video signal 24 is applied to the mixing circuit 8.

The other keying pulse 22 is still applied to the second gate circuit 4, and the video signal 25 which has passed only the portion corresponding to the hair 10 of the hairstyle model 12 is sent to the output terminal of the second gate circuit 4.
is derived and the video signal 25 is applied to the mixing circuit 8.

The video signals 24 and 25 are mixed in the mixing circuit 8, and the composite video signal 26 derived from the output terminal of the mixing circuit 8 is applied to the monitor 9, the reproduced image is observed on the monitor 9, and the second television camera 2 The hair style model 12 from 2005 is replaced with the hair style model 12 of the present invention to select the hairstyle of the subject.

In the above embodiment, a black and white system was explained, but it goes without saying that a color system can also be easily implemented.

Since the hairstyle selection device of the present invention has the above configuration,
The most suitable hairstyle for the subject can be easily selected in advance, and the anxiety about whether the finished hairstyle will suit the subject can be eliminated. The hairdresser can perform the treatment easily and reliably, and the hairdresser does not have to faithfully reproduce the hairstyle on the monitor screen, which improves the hairdresser's technical level. Since the image of the hairstyle model can be freely transformed, even if there are variations in the shape of the subject, the hairstyle model can be matched easily and reliably, and a natural reproduced image without any deviation in the composite part can be displayed on the monitor. Since the hairstyle model is photographed by the second television camera, the hairstyle model can be easily selected from various sources such as magazines.

Claims (1)

[Claims] 1. Means for deriving a video signal from which a signal portion corresponding to the hair of the test subject is removed from the video signal of the first television camera that photographed the test subject; 2. Means for deriving a video signal through which only the signal portion corresponding to the hair of the hairstyle model has passed from the video signal of the television camera, means for mixing the respective video signals and synthesizing the video signal, and means for electrically converting the hairstyle of the hairstyle model. 1. A hairstyle selection device comprising: a means for deforming the hair; the device applies the video signal to a monitor, observes the reproduced image on the monitor, and selects a hairstyle of a subject.
