The image is synthesized by a chroma keyer 194, and the chroma key synthesizes the background image of the external image reproducing unit 103 and the subject image of the camera. After the screen is enlarged / reduced and the effect is processed, the subtitle processing unit 106, the editing system 107, and the external transmitting unit 108 are sequentially passed and then output to the outside.

At the same time, the sound input through the microphone 119 of the recording studio 101 is synthesized together with the synthesizer 124 in the sound mixer 121 through the reverb 120 as shown in FIG. It is output to the speaker 123 via the 122 to give a sound to the composite image output through the external transmitter 108.

In the conventional video synthesizing apparatus as shown in FIG. 3, when the performer 150 listens to the execution of the cue sheet and selects one of several cue sheets through the cue sheet selection input unit 156, the device The operator of the control room enters into the personal computer 155 the cue-sheet selected by the actor.

At this time, the performer 153 selects a song in the karaoke cycle 151, and then sings a song through the microphone 150 according to the accompaniment of the karaoke cycle, the camera 154 captures a subject, such sound and image The information is transmitted to the personal computer 155.

Here, when the equipment operator of the equipment control room operates the computer driving program 157 of the personal computer 155, the image and sound information are adjusted by the screen enlargement / reduction and the effect function of the image effector 159, and thus the image mixer 158. ) And then edited by the image editor 160 and output to the outside through the image output unit 161.

However, a series of image synthesizing operations using such a conventional image synthesizing apparatus is limited only by a predetermined script or cue-sheet, and furthermore, proper synthesis of an actor (subject) image and a background image is performed. It is made only by highly skilled professionals who operate the equipment in this separate equipment control room, which makes it impossible for non-skilled operators to operate and has the limitation of storing synthesized images and sounds directly on the recording medium in real time.

In other words, the conventional image sum growth using chroma key technique is not a low-cost device that anyone can automatically synthesize and edit chroma key images in real time by the simple operation required in the media era, and is too expensive. There are limitations such as price, separate equipment control room and additional facilities, highly skilled equipment operator who can operate it, and actor (subject) must also be skilled person. It has become an obstacle to popularization in the field of image synthesis using the technique.

The present invention provides a self-image synthesis apparatus that can produce a professional image using the chroma key image effect as it is by the simple operation of the functional control unit, and can contribute to popularization because the price is significantly lower than in the past. There is a purpose.
