Referring to FIG. 1, in the present embodiment, a window display unit 1 that displays image data and the like on a window, and a display image enlargement / reduction that enlarges / reduces the displayed image data according to the window display size (display area). A processing unit 2, an image data input unit 3 for inputting image data to be displayed, a window size management unit 4 for acquiring one or a plurality of window sizes for displaying the image data, and a user displaying the image data. When the window size is updated, a display window size input unit 5 for acquiring an updated new window size, and a predetermined audio output level based on a ratio between the updated new window size and the predetermined window size. And an audio output level calculator 6 for calculating an updated new audio output level, and an audio data inserted into the image data. Audio data input unit 7, an audio output control unit 8 which amplifies or attenuates the input data to the corresponding level set in the audio output level calculation section 6, the audio output control unit 8 for
The audio output unit 9 outputs the audio data amplified or attenuated by.

Next, the operation of this embodiment will be described with reference to FIGS.

Normally, in a computer capable of displaying a window, a window area securing process 10 is performed as the first procedure for displaying an image in a window. Therefore, even when displaying a plurality of windows, a plurality of processes are required. The window in which the window area is secured is a display window size input unit 5 for acquiring the newly changed display window size only when the display size of the window currently being watched by the user is changed.
Given by This operation corresponds to the procedure of the window size change request 11 in FIG. The newly changed new window size obtained from the display window size input unit 5 is held in the window size management unit 4, and manages the state of the display window size of a plurality of windows (new window size acquisition processing 12). Next, the audio output level calculator 6 calculates a new audio output level from a predetermined audio output level.

A predetermined standard window size is W (x, y), a previously held new window size is NW (x, y), and a correction function for weighting according to auditory characteristics is C (x, y). y), the conversion coefficient F (x, y) for calculating the new audio output level is given by the equation (1).
More required.

F (x, y) = NW (x, y) / W (x, y) * C (x, y) (1) Here, the horizontal size of the display window is x, and the vertical size is Let the size be y.

The conversion coefficient F obtained as described above
A new audio output level NWSL (x, y) is calculated from equation (2) from (x, y) and a predetermined reference audio output level SL.

NWSL (x, y) = F (x, y) * SL (2) As described above, the audio output level calculation processing 13 performed by the audio output level calculation unit 6 outputs the audio according to the window display size. Since the level is variable, it is possible to set an auditory information amount (audio output level) suitable for the visual information amount obtained from the display window size. After the audio data inserted into the image data, which is input from the audio data input unit 7 as a parameter of the audio output control unit 8, is amplified or attenuated to the new audio output level obtained by the audio output level calculation unit 6, It is sent to the audio output unit 9 and is output at an optimal audio output level according to the display window size (audio output level setting output processing 16).

On the other hand, the image data displayed in the window is input from the image data input unit 3 after the inserted audio data is separated, and is enlarged or reduced and stored in the window size management unit 4. The display image enlargement / reduction processing unit 2 performs the display image enlargement / reduction processing 14 based on the new window size. The enlarged / reduced display image is output to the display window unit 1 in which the window area is previously secured in the in-window display processing 15 of the image, and can be displayed according to the display window size specified by the user.

FIG. 3 shows an enlarged window W1.
A specific example of enlargement of a display image when the display size is changed to the display size of the window W2 will be described.

The above description is an example in which the display window size is obtained from the display window size input unit 5 only after the change of the display window size is determined, and the audio output level is determined to provide the optimum sound volume. However, the same effect can be obtained in a real-time processing system in which the display window size is monitored at a fixed cycle and a new window size is acquired each time.

[0022]

As described above, according to the present invention, in the display of image data in which sound is inserted, the output level of sound is changed according to the size of the image display window.
Since the audio output can be automatically muted when the display window is minimized, the optimal amount of auditory information (audio information) is given to the data user in accordance with the amount of visual information (image information). There is an effective audiovisual effect that increases the sense of presence and reality.
