Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image composition apparatus, and more particularly to an image composition apparatus for a plurality of stationary television (TV) images.

Conventionally, the conventional method for combining multiple still images by punching them in is to convert the images into electrical signals and process them, and generally, the images are processed digitally using an image processing device using a computer. Process and synthesize. However, this method handles a huge amount of data, takes time to process, lacks immediacy, and requires a complex operating method, requiring a skilled operator.

Taking the example of the clothing try-on system that has become increasingly popular in the fashion world in recent years, rather than having customers come to a store try on actual garments, the system displays the customer's desired clothing on a TV screen. When considering an image synthesis system that displays clothing samples as if they were being tried on, the computer-based image processing method described above is impractical because it takes too much processing time and is not easy to operate.

Therefore, an object of the present invention is to combine a digital special effects device with screen scaling and movement functions, a chromakey device, and a video mixing amplifier, thereby achieving faster and easier image synthesis processing than conventional computer image synthesis processing. An object of the present invention is to provide an image synthesis device capable of synthesizing images of a person, clothes, and background.

According to the present invention, a camera for photographing a person, an image file in which images of specimens such as clothing and backgrounds are stored in advance, and image output signals of the camera and image file and reproduction signals of an image memory to be described later can be switched and selected. a digital special effects device inserted into one side of the output string of the switcher, a video mixing amplifier whose inputs are the output of the digital special effects device and the output of the other output string of the switcher; A method for synthesizing multiple images consisting of a line chromakey device for applying a gate signal for masking to an amplifier, an image memory for recording the output image of the mixing amplifier, and a video monitor for displaying these screens. 〓〓
An image synthesizing device is obtained.

The invention will now be described in detail with reference to drawings of embodiments of the invention. The drawing is a configuration diagram of an embodiment of the present invention. In the figure, a color TV camera 1 photographs a person 2 standing in front of a blue stand 3. In addition, the image file 4 electrically records and stores a large number of images of clothing specimens and landscape images that serve as the background of the composite image. Clothes specimen files are usually created as follows. First, dress a model or mannequin in the clothing you want to use as a sample, take a photo of it, cut out only the clothing part of the photo, paste it on a blue mount, and take a photo of it with a TV camera to create a still image. input into the image file as . For landscapes, take still photos with a TV camera and input them into image files. Next, in the video switcher 5, the output of the output train A is input to the video mixing amplifier 8, and the output of the other output train B passes through the digital special effects device 6 and the video processor 7, and then the output of the other output train B passes through the digital special effects device 6 and the video processor 7. added to the input. The digital special effects device 6 is a device that digitizes video signals and has functions for enlarging, reducing, and moving images. The line chromakey device 9 detects the blue component of the output signal of the special effects device 6, generates a gate signal for the portion to be masked, and supplies it to the mixing amplifier 8. The reproduction output of the image memory 10 is input to the switcher 5. The color video monitor 11 is a mixing amplifier 8
The operation panel 12 is used to operate the above system.

Next, details of the operation of the present invention will be explained. First, a method for combining images of a person and clothing will be explained.
The output of the camera 1 which has photographed the person 2 is inputted to one input side of the mixing amplifier 8 via the A row of the switcher 5. Also, from the image file 4, the signal of the sample image of the selected garment is transferred to the B of the switcher 5.
It is selected in the column and input to the other input side of the switcher 8 via the special effects device 6 and the video processor 7. The mixing amplifier 8 synthesizes these two input images, and in this case, the gate signal from the line chroma key device 9 allows only the blue back part of the clothing image to be combined with the image in column A,
In other words, the images of the person are combined to obtain an image in which the person is covered with clothing. The relative positional relationship between the person image and the clothing image is determined by operating the special effects device 6 using the joystick on the operation panel 12 while viewing the video monitor 11, and adjusting the position and dimensions of the clothing image as if the person were wearing the clothes. I can do it. Similarly, by enlarging/reducing the special effect device 6 only in the vertical direction or in the horizontal direction, it is possible to synthesize clothing that fits the shape of the person's body. Furthermore, by changing the brightness and hue of the clothes using the video processor 7, an image of the person wearing clothes that most closely matches the color of the person's hair or skin can be obtained. The composite image of the person and clothing obtained as described above is stored in the image memory 10.
It is stored in one place.

Next, a method for further compositing this composite image with a background image will be explained. In the figure, the background image output selected from the image file 4 is input to the mixing amplifier 8 through the A column of the switcher 5. On the other hand, the reproduction output from the image memory 10 is taken to the B column of the switcher 5, and is inputted to the mixing amplifier 8 via the special effects device 6 and the video processor 7. The mixing amplifier 8 synthesizes these two input images, but at this time, since the back color of the composite image of the person and the clothes is blue, it is branched from the special effects device 6 and passed through the chromakey device 9 to create a mask. A gate signal is obtained, and using this gate signal, the mixing amplifier 8 obtains an image in which the composite image of the person and clothing is embedded in the background in exactly the same manner as described above.

Similarly, by operating the special effects device 6, the size of the composite image of this person and clothing can be adjusted.
and its position on the screen can be adjusted arbitrarily.

As described in detail above, a composite image of three images of a person, clothing, and background is obtained on the video monitor 11. In the above explanation, it is assumed that the back color of the person and the clothes are blue, but if the clothes are blue, you can change the back color to yellow, set the line chroma key mask hue to this color, and perform the same operation. It is clear that it is possible to do this.

In this embodiment, the case of clothes has been described, but the present invention can also be used to simulate the color scheme and layout of indoor interiors, or to simulate the design of architectural landscaping, etc. Generally, multiple images are combined, It is effective as a means to obtain a visual simulated image.

〓〓〓〓〓
As explained above, the present invention combines a digital special effects device with image scaling and movement functions, a chromakey device, a video mixing amplifier, and an image memory, so that multiple images can be moved to any position and size. It has an effect that can be synthesized and is extremely quick and easy to perform.
