Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of a moving image processing apparatus according to one embodiment of the present invention.

As shown in FIG. 1, the moving image processing apparatus according to the present embodiment includes a CPU (central processing unit) 1, a keyboard (KB) 2, a liquid crystal display (LCD) 3, and a video RAM (VRAM). 4, ROM 5, RAM 6,
A video disk device (VDISK) 7 and a speaker (S
P) 8 and a bus 9.

The CPU 1 is connected to the components 2 to 8 via a bus 9 and controls the components.

The keyboard 2 has keys for instructing and executing various controls and keys for inputting characters.

The LCD 3 is, for example, a color LCD, and displays characters and images written in the VRAM 4 which is a write-only memory for display as a font pattern or image image to be described later.

The video disk device 7 is a device for storing moving image data.

The ROM 5 is a read-only memory,
The inside is mainly divided into a program area PRG for storing a program for executing image processing and a font pattern area FONT for storing font patterns such as characters and symbols for displaying subtitles.

The RAM 6 is a writable memory,
The inside is divided into a plurality of areas as follows.

The area WORK is a work area for temporarily storing program variable data, constant data, and other information in order to operate the above-described program.

The area GAM is a screen area in which a moving image is digitized and stored.

The area SOU is a sound area in which an audio signal is digitized and stored.

The area JIM is a subtitle area for storing subtitles.

The area TIME is a timer area for controlling the display time of one image data.

The area TBL is a time table area indicating switching of the reproduction speed of a moving image.

FIG. 2 is a diagram showing each data structure of image data stored in the screen area GAM and audio data stored in the sound area SOU.

In the figure, a moving image is composed of a set of still images updated every 1/30 second, and is numbered GAM (1), GAM (2)... From the first frame.

On the other hand, the audio data is similarly numbered SOU (1), SOU (2),.

The image data is stored in the VRAM 4 every 1/25 second.
, And the screen is viewed as a moving image. Of course, the audio data is continuously converted into analog data every 1/25 second without interruption, and output from the speaker 8.

FIG. 3 is a diagram showing the relationship between caption data stored in the caption area JIM and image data stored in the screen area GAM.

In the figure, subtitles are units displayed at one time, and are numbered JIM (1), JIM (2)... From the beginning, and store character codes. Since the same subtitle is displayed on a plurality of screens, the head and the end of the screen number for displaying the subtitle are stored as a pair corresponding to each subtitle.

In the example shown in the figure, the cell number JIM (1) stores the screen numbers “1” and “30” as a pair.
While the screens 1 to 30 are displayed, the cell JIM
This means that the subtitles in (1) are displayed simultaneously.

The cells GAM (31) to GAM (4
Subtitles do not exist in the images up to 9).

FIG. 4 is a diagram showing a screen display area of the LCD 3 and a subtitle display area for displaying subtitles.

In the figure, the outer area indicates the screen display area, and the area 3a indicates the subtitle display area. For the subtitles, a font is searched from the character code, and the font pattern is written in the VRAM 4,
It is displayed at the position of the area 3a.

Next, a description will be given of a moving image reproducing process executed by the moving image processing apparatus configured as described above.

Although there are various methods for inputting an image, a digital broadcast may be stored in the video disk device 7 via an antenna and a tuner (both not shown), or may be recorded from the beginning. A video disk may be set in the video disk device 7. Either method can be easily realized by existing technology. Here, the image is assumed to be a digital image. A part of the existing image and sound is compressed and recorded again, which is generally called nonlinear editing. The re-edited data is temporarily stored in the RAM 6, but since the capacity is enormous, the data is processed and saved again on the video disk.

FIG. 5 is a diagram showing the effect when a part of the image and sound is compressed.

In the figure, (a) is an original image.
“Yes” indicates a portion having a sound, and “No” indicates a portion without a sound. As shown in (b), the portion with sound is copied with the same length, and the portion without sound is copied with half the length. By performing such processing, the overall length is shortened. The extent to which this can be reduced depends on the length of the portion without audio and the compression ratio.

FIG. 6 shows a moving image processing apparatus according to this embodiment.
6 is a flowchart showing a procedure of an image display process executed by the CPU 1 in particular.

In the figure, first, the timer area TI
The software timer TIME formed on the ME is reset to "0" (step S1). This timer T
The IME is configured to be added every 1 ms, and the image is 1/25 second for standard playback, so every 20 ms, and 1/50 second for fast-forward playback, so that the image is 20 m long.
An image will be displayed every s. It is a counter for that.

Next, the sound area SOU shown in FIG. 2 is checked (step S2), and the process branches depending on whether there is audio data (step S3).

In step S3, if there is audio data, standard reproduction is performed.
Write to 4. Therefore, it is necessary to wait for 40 ms. Although not shown, the timer TIME is counted up by the timer interrupt and waits until the time reaches 40 ms (step S4).

Thereafter, the image data is written into the VRAM 4 and displayed on the LCD 3 (step S6).

On the other hand, if it is determined that there is no voice,
Set the timer wait to 20 ms. That is, this is for displaying images at 1/50 second intervals of double speed. Therefore,
After waiting for 20 ms (step S5), the image data is written to the VRAM4.

Thereafter, it is determined whether or not the last image is present (step S7). If not, the process returns to the timer TIME "0" reset processing in step S1.

Note that this flowchart is limited to the display of images only, and audio data is converted to analog and output to the speaker 8 separately. Since it can be easily achieved by a known technique, the description of the processing procedure is omitted.

In this way, standard reproduction is performed where there is audio information, and double speed reproduction is performed where there is no audio information.

In this embodiment, the display speed of an image is adjusted by detecting the presence or absence of sound. However, the display speed of an image can be adjusted by detecting the presence or absence of subtitles.

FIG. 3 shows the memory structure of the caption information. The screens having the caption information are 1 to 30, 50 to 60.
It has become. That is, standard reproduction is performed for the first to 30th images, double-speed reproduction is performed for the 31st to 49th images without subtitles, and standard reproduction is performed for the 50th to 60th again. Since the processing procedure is almost the same as the flowchart of FIG. 6, illustration and description thereof will be omitted.

In the present embodiment, the image playback speed is adjusted by the screen number, but it is also possible to adjust the playback time instead of the screen number.

For this purpose, a time table of the start times of the standard reproduction and the high-speed reproduction may be created, and the display speed of the image may be adjusted based on the time table.

FIG. 7A is a diagram showing a time table for standard reproduction and high-speed reproduction. If the start of the table is determined to be the standard playback time, the subsequent data alternately becomes the time of the high-speed playback and the standard playback.

Looking at the actual table example, 0: 00: 00: 00
Seconds, that is, a state in which standard reproduction is to be performed from the beginning, and a time to be reproduced at high speed from 0: 0: 30.

The method of switching between the standard reproduction and the high-speed reproduction may be either the method with or without audio or the method with or without subtitles. If control of standard reproduction and high-speed reproduction can be realized by the presence or absence of audio or the presence or absence of subtitles, this time table can be created by a simple calculation.

Next, the actual reproduction time is reconstructed from the time table. That is, it is necessary to halve the time of a portion to be reproduced at high speed. The result of the operation is
FIG. 7 (b). High speed playback from 0: 0: 30 to 0
One minute of the hour, one minute and thirty seconds is shortened to thirty seconds, and the next standard playback is set to 0:00:01. Standard playback and high-speed playback may be alternately switched according to this time table.

However, for example, if the sound is suddenly switched from a certain scene to the standard reproduction, the head portion is difficult to hear, so that the standard reproduction may be reproduced a little before, for example, three seconds before. FIG. 8 is a diagram showing an example of the table in that case. That is, the standard reproduction start time is advanced by 3 seconds as compared with FIG. This makes it easier to hear the sound when switching to standard playback.

In the present embodiment, the high-speed reproduction is performed at double speed of the standard reproduction, but may be performed at a higher or lower speed. In addition, the reproduction speed of the screen is switched depending on the presence or absence of the sound. Further, the transfer rate of the image data is 1/25 seconds in the standard reproduction, but may be finer or coarser.

A storage medium storing software program codes for realizing the functions of the above-described embodiments is supplied to a system or an apparatus, and the computer (or CPU 1 or MPU) of the system or the apparatus stores the storage medium in the storage medium. It goes without saying that the object of the present invention is also achieved by reading and executing the program code.

In this case, the program code itself read from the storage medium realizes the novel function of the present invention, and the storage medium storing the program code constitutes the present invention.

As a storage medium for supplying the program code, for example, a floppy disk, hard disk, optical disk, magneto-optical disk, CD-ROM,
CD-R, magnetic tape, nonvolatile memory card, RO
M5 or the like can be used. Further, the program code may be supplied from a server computer via a communication network.

When the computer executes the readout program code, not only the functions of the above-described embodiment are realized, but also an OS or the like running on the computer operates based on the instruction of the program code. It goes without saying that a part or all of the actual processing is performed, and the functions of the above-described embodiments are realized by the processing.

Further, after the program code read from the storage medium is written into a memory provided in a function expansion board inserted into the computer or a function expansion unit connected to the computer, based on the instruction of the program code, It goes without saying that the CPU included in the function expansion board or the function expansion unit performs part or all of the actual processing, and the functions of the above-described embodiments are realized by the processing.
