Abstract

(57) [Summary] [Problem] To create a pseudo moving image using an existing still image even when a new original image cannot be created. In addition, pseudo-moving images are generated at high speed in synchronization with instantaneous high-speed actions such as sound effects. SOLUTION: After using existing still image data 100 or after converting an analog still image into digital data, a digital operation process is performed to synchronize a viewpoint for viewing an image, that is, a virtual camera 102 with a sound effect or a dialogue. Exercise in a simulated manner and obtain a pseudo video. Since the movement of the viewpoint is performed by digital computation, high-speed image presentation such as synchronization with an impact sound is also possible.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for presenting an image which realizes a pseudo moving image which moves in conjunction with a sound effect or a dialog using an original still image.

[0002]

2. Description of the Related Art A method of expressing a pseudo-moving image by expressing related images in digital data and presenting the digital images successively is known by animation and the like. This method has no problem when creating a new image. Therefore, there is a demand for creating a pseudo moving image, and an appropriate method for realizing this is desired.

In this regard, a method of obtaining a pseudo moving image by moving the camera position with respect to a still image is usually performed. Although not a still image, the diorama relies on this method.

[0004]

SUMMARY OF THE INVENTION The present invention provides means for creating a pseudo-moving image by using a still image of a still image that already exists, even when a new image cannot be created. Further, the present invention provides a method of generating a pseudo moving image at high speed in synchronization with an instantaneous high speed action such as a sound effect.

[0005]

According to the present invention, existing still image data is used, or an analog still image is converted into digital data, and then the viewpoint for viewing the image is simulated by digital arithmetic processing. Realize the required pseudo video. Since the movement of the viewpoint is performed by digital calculation and is not a physical movement of the camera, high-speed image presentation such as synchronization with an impact sound is also possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a method for presenting an image according to the present invention will be described below.

Embodiment 1 FIG. 1 is a diagram for explaining an image presentation method according to the present invention. 100 is a still image, 101 is that part, 102 is a virtual camera, and 103 is virtual lighting.

In order to obtain an image of the original image 100 viewed from a virtual camera 102 located in a space separated from a still image, a screen element is digitally operated by giving relative coordinates between the camera and the original image. As a result, the partial image 101 is calculated as the output of the virtual camera 102. Elements related to the calculation include the relative positional relationship between the still image and the camera, the angle of the optical axis of the camera with respect to the still image, the rotational relationship between the camera and the image, the tilt angle of the camera, and the like. These can be easily calculated by calculation of geometrical optics using a microcomputer or the like.

On the other hand, the brightness of the still image screen is calculated based on the distance and angle between the virtual illumination 103 and the pixels in the still image. Although a point light source is illustrated in the drawing, the calculation of a surface light source or a line light source is also easy. There may be a plurality of lights, and color lights may be used.

In order to move the virtual camera 102, the position information of the camera and the posture information such as the tilt and the rotation may be continuously given to the calculation formula. The lighting can be moved similarly.

In the simplest case, the camera is moved in parallel to the screen in accordance with the sound effects and dialogue. As a result, a continuously changing moving image is obtained from one still image.

As a more complicated example, if a still image is a manga and a collision scene is assumed, if the camera position is vibrated up, down, left, right, up and down in synchronization with the sound effect “Gachan”, the original image becomes one still image. Despite being a picture, a moving picture effect that gives a sense of vibration and impact can be obtained. Further, by instantaneously increasing the illumination illuminance or changing the color to red, yellow, or the like in synchronization with this, the sense of impact can be further enhanced.

Second Embodiment In the first embodiment, the original image is treated as a plane. In the second embodiment, the original image is mapped onto a spherical surface, a cylindrical surface, or the like, and then subjected to the same digital calculation processing as in the first embodiment.
Get even more interesting image effects.

The curved surface in this embodiment may change over time. For example, a "carpet" that floats in space while swelling
By mapping an image on the surface and giving a viewpoint movement thereto, a complex and fantastic screen can be presented.

[0015]

As described above, according to the present invention, even when a new image cannot be created, a pseudo moving image can be created by using an existing still image of a human image or the like. Further, according to the present invention, a pseudo moving image can be generated at high speed in synchronization with an instantaneous high-speed action such as a sound effect, and a pseudo moving image can be easily and effectively obtained from an original still image.

The method of presenting an image of the present invention is particularly effective in the case of manga. In other words, manga often expresses movements and actions, but due to the limitations of still images, movements are represented by scattered stars or lines that cut the wind.
According to the presentation method of the present invention, the screen itself can be swung in synchronization with the sound effect, and the action can be effectively expressed.
