Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image synthesizing device that synthesizes a plurality of images to create a new image.

The present invention is used, for example, in selecting products such as costumes and interior furniture. In the case of costumes,
It also synthesizes and replaces new images of clothing, accessories, hairstyles, etc. with the customer image, creating an image that looks as if the customer is wearing the product they are currently selecting, making it easier for the customer to select a product. Applied.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments. A binarized still image signal is stored in a reference image memory 2 from a reference image generator 1 comprising, for example, a color television camera and an analog-to-digital converter. The still image signal from the reference image generator 1 is, for example, an image of a customer in a fashion application, or an image of a current room in an interior application. on the other hand,
One type of binarized addition image selected from an addition image file memory 3 composed of a magnetic disk or the like is stored in an addition image memory 4. The content of this added image is, for example, an image of clothing in a fashion application, and an image of furniture, etc. in an interior application. The added image from the added image memory 4 can be processed by a deformation circuit 5 that processes the image signal so as to deform the geometrical shape of the image, and can change the density information of the image signal such as the brightness, contrast, hue, saturation, etc. of the image. Addition circuit 7 through concentration change circuit 6
into one input. The other input of the adder circuit 7 receives the binarized reference image signal from the reference image memory 2 . For example, the addition circuit 7, which is composed of two multipliers and a summation unit, weights each of the two input image signals based on the key signal from the key signal memory 13 that has been processed by the key signal correction circuit 12. The added image signals are supplied to the preview monitor 9. The preview monitor 9 displays the composite image output of the adder circuit 7 as an image by converting the input image signal into an analog quantity and displaying it on, for example, a cathode ray tube of a television receiver. In the case of application for fashion, the silhouette of a costume is taken as a key signal, and the weight of the added image from the added image memory 4 processed by the transformation circuit 5 and the density change circuit 6 is set to "1" only for the silhouette part of the costume. By setting the weight of the reference image from the reference image memory 2 to ``0'', conversely setting the weight of the addition image to ``0'' and the weight of the reference image to ``1'' for other parts, the preview can be The image displayed on the monitor 9 is an image of the customer wearing the costume selected from the added image file. Further, the composite image output of the adder circuit 7 can be input to the reference image memory 2. With this configuration, in the case of application to fashion, a composite image of a certain costume and a customer selected from the added image file memory 4 is stored as a reference image in the reference image memory 2, and then another image is stored as the added image again. ,
For example, by selecting and composing accessories, hats, hairstyles, etc., two types of images, such as a customer's image and clothing, accessories, etc., can be composited.

By repeating the above steps, it is possible to synthesize a large number of images with a simple circuit configuration.

The key signal that determines which of the reference image and the addition image to select and add in the addition circuit 7 often depends on the boundary line information of the addition image and the area information surrounded by it.
The key signal corresponding to the added image is stored in the added image file memory 3, and when a certain specific added image is selected, the key signal corresponding to the added image is transferred to the key signal memory 13. You can also. Of course, depending on the images of the addition image and the reference image, the boundaries and areas are determined by the image calculation circuit 1.
5, and the result can be used as a key signal. The deformation circuit 5 that deforms the geometric shape of the added image is controlled by a shape correction table signal from the shape correction table generation circuit 10, and the shape correction table is processed by the control circuit 14, such as a joystick, a tablet, etc. Input circuit 16 consisting of
modified by signals from This allows the user of this device to manually transform the added image freely. Further, the density change circuit 6 that changes the density information of the added image includes a density correction table generation circuit 11.
It is controlled by a density correction table having two types of information: spatial position and correction amount from the control circuit 14, and this density correction table can be modified by a signal from the input circuit 16 processed by the control circuit 14. With this configuration,
The user of this device can partially change and modify the density of the added image. Further, in order to erase part or all of the added image or the reference image from the composite image, the key signal from the key signal memory 13 is corrected by the key signal correction circuit 12. That is, in order to erase, the weight of the portion to be erased can be changed to "0". In order for the user to do this as desired, the key signal correction circuit 12 is controlled by a signal from an input circuit 16 through which a control circuit 14 passes. Compared to erasing the reference image and addition image signals themselves stored in the reference image memory 2 and addition image memory 4, the method of correcting the key signal and erasing the image according to the present invention is useful when erasure itself is inconvenient. , has the advantage that the erasure operation itself can be canceled. When the user obtains the desired image on the preview monitor 9, the composite image is transferred to the main image memory 8, where the completed composite image is stored.

As described above, the present invention is an image synthesizing apparatus that has an excellent effect of being able to interactively synthesize images without causing any discomfort by sequentially synthesizing images.
