DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transparently synthesizing an image to be synthesized with an image to be synthesized.

[0002]

2. Description of the Related Art Conventionally, there have been known various transmission synthesizing methods of an image for displaying an image to be synthesized as a part of an image to be synthesized. As one example, Japanese Patent Application Laid-Open No. 4-45487 discloses that a window to be displayed on an already displayed image is given a transparent or opaque attribute, and when the window with the transparent attribute is displayed, the window is already displayed. A technique has been disclosed in which a logical sum process is performed with an image that has been performed to obtain a composite display with a base image.

[0003]

However, in the technique described in Japanese Patent Application Laid-Open No. 4-45487, it is necessary to process the synthesis target image itself displayed in the window and add a transparency attribute. There was a problem that the processing became complicated. Also, since the transparency attribute must be added to the composition target image itself by processing it, the position of the window that displays the composition target image in the composition target image can be changed in real time, or the composition target image can be dynamically moved. Could not be synthesized.

An object of the present invention is to solve the above-mentioned problems,
It is an object of the present invention to provide a method of transmitting and synthesizing an image which does not need to be processed at all into an image to be synthesized and an image to be synthesized.

[0005]

According to the present invention, there is provided a method of transmitting and combining images, the method comprising transmitting and combining a plurality of images. The method comprises the steps of: By displaying an image to be combined and an image to be combined inside and outside of the image, transparent synthesis of the image to be combined and the image to be combined is performed.

[0006] In the present invention, the transparent composition of an image to be combined and an image to be combined is all controlled by combining information of external data, so that the image to be combined and the image to be combined itself have a transparent attribute. By manipulating the synthesis information without requiring any processing, it is possible to perform transparent synthesis of the image.
Further, as a preferable mode, by operating the synthesis information in the same manner, the synthesis is performed such that the position of the window displaying the synthesis target image in the synthesis target image is changed in real time, or the synthesis target image is dynamically moved. be able to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a diagram for explaining an example of a method for transmitting and combining images according to the present invention. In the example shown in FIG. 1, (A) is the image to be combined, (B) is the image to be combined,
(C) is synthesis information, (D) is an image of a synthesis result to be finally displayed, and (W) is a position of a window to be synthesized.
In this example, when the image to be combined is (B) and the point at the upper left corner of each image is the origin as the window (W),
The point of (X ₀ , Y ₀ ) is set as a starting point, and (X,
Consider a rectangular window (W) of size Y).
Therefore, the synthesis information (C) includes the position (X ₀ , Y ₀ ) of the window (W) and the shape (rectangular, X,
Y), a composite image (B image).

A feature of the present invention is that when the image of the image to be combined (B) is displayed at the position of the window (W) of the image to be combined (A), the information of the combination information (C), that is, in this example,
Based on the position of the window, the shape of the window, and the information of the image to be combined, the corresponding portion of the image to be combined (B) is placed inside the window (W) and the image to be combined (A) is placed outside the window (W). This is the point that the image (D) of the synthesized result to be finally displayed is obtained by displaying the portions to be displayed. Therefore, in the present invention, the image to be synthesized (A) and the image to be synthesized (B) themselves do not require any processing such as the addition of a transparency attribute, and the transmission of the image can be performed by operating the synthesis information (C). Synthesis can be performed.

Next, the application of the image transmission synthesis method of the present invention will be described. FIG. 2 shows a preferred example of the present invention.
FIG. 9 is a diagram for explaining re-synthesis (re-synthesis) of images. In the example shown in FIG. 2, the position and shape of the window (W) in which the image to be combined (B) is to be displayed, that is, the position and shape of the window surrounding the balloon can be changed in real time. That is, the position and shape data of the window of the composite information (C) is rewritten in real time by, for example, a mouse operation by the user, and the display is performed based on the rewritten composite information (C). The position of the window can be moved by moving the mouse pointer to a position in the window and dragging the mouse vertically, horizontally, or in a single-clicked state. To change the shape of the window, move the mouse pointer to the position of the window border,
By dragging up, down, left and right with a single click, the shape can be changed with the start point of the window as the fixed point.

FIG. 3 is a diagram for explaining a combination aiming at a spotlight effect as a preferred example of the present invention. As an example shown in FIG. 3, the combined image (A) is set to be solid black,
By displaying the composition target image (B) in a circular window (W) and moving the window (W) in real time based on the composition information (C), a spotlight-like display can be performed. The composition target image (B) changes the part of the image to be displayed in synchronization with the movement of the window (W) as the window (W) moves.

FIG. 4 is a diagram for explaining a composition for implementing a simple animation as a preferred example of the present invention. FIG.
