Three-dimensional graphic processing system and method capable of utilizing camera preview images

A three-dimensional (3D) graphic processing method comprising the steps of:

• generating a camera preview image by processing input data received from a digital camera with a preview function;
• storing texture data or camera preview image data from a host in a texture memory according to a texture source selection signal from the host;
• and
• executing a 3D graphic process by using texture data or camera preview image data stored in the texture memory as a texture according to a graphic processing command from the host.

A three-dimensional (3D) graphic processing method comprising the steps of:

• preview processing a video data photographed through an image sensor;
• storing the obtained preview image in a texture memory;
• and
• executing a 3D graphic process using the stored preview image as a texture.

A three-dimensional (3D) graphic processing method comprising the steps of:

• photographing an image of an object through an image sensor;
• signal-processing the received image data of the object and storing the signal processed result in a first memory, and generating a preview image;
• processing to resize the received input image data in the case that the input image stored in the first memory is valid data;
• storing the generated preview image data in the second memory;
• and
• executing a 3D graphic process by using the preview image data stored in the second memory as a texture, by a 3D graphic processor.

A method of making up three-dimensional (3D) graphic contents using a real background image comprises the steps of:

• taking a picture of an actual background image through the image sensor;
• preview processing video data of the photographed background image;
• storing the obtained preview image in the texture memory;
• drawing two large triangles corresponding to a background by using the preview image as a texture;
• and
• drawing a 3D object over the actual background image.
