- the drawn image thus combined is sent to the CRTC 16 by which the image is converted to a video output signal and outputted as a video output signal (step S205).
- the combined image is displayed on a predetermined display unit by the video output signal.
- any one of two images to be combined is temporarily stored in the auxiliary storage device 29, making it possible to obtain image information from the same input channel.
- image information previously obtained is temporarily stored in the auxiliary storage device 29, and then different image information is obtained from the same input channel later.
- the auxiliary storage device 29 may directly store image information previously obtained, or store it after decoding. Image information stored in the auxiliary storage device 29 may be read as required. Examples
- the information processing apparatus that performs the foregoing image combination processing can generate the following images.
- Example 1
- FIG. 4A illustrates the process of generating image information from an image with high resolution (a frame image which is part of the moving image)
- FIG. 4B illustrates the process of generating an image with high resolution from received image information. This image represents "/".
- the main image information has moving image information, serving as an image, and frame number information for each of frame images that form the moving image.
- the main image is a moving image that is obtained by reducing the resolution of the moving image with high resolution such as an image shot for high definition to one for radio broadcast from the broadcast station 3.
- the additional image information is image information for increasing the resolution of the image based on the main image information. Namely, the additional image information corresponds to image information serving as an image C illustrated in FIG. 4A.

- the image C of FIG. 4A corresponds to an image for increasing resolution illustrated in FIG. 4B.
- the main image information is broadcast from the broadcast station 3 and that the additional image information is transmitted from the server station 2. It is further assumed that the image combination is performed by the main CPU 10.
- the main image information is broadcast from the broadcast station 3 and inputted to the tuner 30 via the antenna ANT.
- the tuner 30 extracts only information of the selected channel and sends it to the MDEC 13.
- the MDEC 13 decodes the received information to generate a main image, and sends it to the main CPU 10.
- the MDEC 13 also extracts frame number information from the main image information sent from the tuner 30. The extracted frame number information is also sent to the main CPU 10.
- the additional image information represents a difference between the image A and the image B. For this reason, additional image information is normally generated by the broadcast station 3 and sent to the server station 2. Then, the additional image information is inputted to the ATM 26 from the server station 2 via the network 4a. The inputted additional image information is decoded by the main CPU 10. The main CPU 10 generates an additional image.
- the main CPU 10 combines the main image sent from the MDEC 13 and the additional image decoded by the main CPU 10, and generates a display list. The combination is performed in synchronization with frame number information such that completely different screen pages are not combined.
- the display list generated by the main CPU 10 is sent to the GPU 14, and is drawn on the frame memory 15. Thereafter, the drawn image is sent to the CRTC 16, and converted to a video output signal. By displaying this video output signal on a predetermined display unit, an image with high resolution is obtained.
- Example 2 The generation of image in this way makes it possible to display an image with resolution, which is based on the conventional broadcast, as an image with high resolution. Accordingly, the high-quality broadcast can be implemented by using the conventional broadcast facilities.

- these image display lists are drawn in the same area to be superimposed on each other, so that the image for left eye as a main image and the image for right eye as an additional image are combined.
- the drawn image on the frame memory 15 is sent to the CRTC 16 and converted to a video output signal.
- This video output signal is displayed on a predetermined display unit, so that a stereoscopic image is obtained.
- the generation of image in this way makes it possible to display a conventional monaural image as a stereoscopic image.
- the stereoscopic image can be implemented by dividing the same image into two, namely, a main image and an additional image. More specifically, if the main CPU 10 generates a display list in such a way that one image is shifted by one to several pixels with respect to the other image, a stereoscopic image is formed when both images are combined.
