Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixed position running device for running at a fixed position. In particular, the present invention relates to a fixed-position running device for reproducing an image recorded on a recording medium by a reproducing device and displaying the image on a television receiver so that a runner can run without getting tired.

[0002] Conventionally, as a fixed position running device having such a running course image function, Japanese Patent Laid-Open No. 54-159.
The one described in Japanese Patent Publication No. 030 is known. In this conventional fixed-position running device, a running course with a scenic landscape in the background is recorded on a video tape, which is played back by a video tape recorder and displayed on a television receiver. The step speed is detected and the video tape playback speed is controlled according to the speed, and if the runner's speed becomes faster, the playback speed will be increased accordingly. Conversely, if the runner's speed becomes slower, the playback speed will be decreased accordingly. It is like this.

[0003]

However, varying the reproduction speed of the video tape in an analog manner according to the stepping speed of the runner makes the structure complicated, the cost becomes high, the practicality is poor, and the product is commercialized. Was difficult.

It is an object of the present invention to provide a fixed position running device having a running course image function which is inexpensive and highly practical.

[0005]

A fixed position running apparatus according to the present invention comprises a step detecting means for detecting a stepping motion of a runner, and a step counting means for counting the number of steps by a signal from the step detecting means. It is provided with a control means for advancing the reproduction by the reproducing device by one frame each time the preset number of steps is reached.

The control means determines whether or not the next information recorded on the recording medium is audio information from the control program or the identification code of the recording on the recording medium. Control the information to be played immediately.

A compact disc (C
It is preferable that D) is used and reproduced by a CD-ROM device.

[0008]

According to the fixed position running device of the present invention,
The image information is reproduced one frame at a time, and the reproduced image is sent one frame each time the runner runs and the number of steps exceeds a preset number of steps. If the next recording information is audio information, it is immediately reproduced as audio.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram of an image and sound reproduction system in a home position running device according to the present invention. In this example, a compact disc (hereinafter referred to as a CD) is used as a recording medium.
Is used), and the image information and audio information recorded therein are read by the CD-ROM device 10.

Image information and audio information are compressed (encoded) and recorded on a CD as is well known. In this case, the image information is recorded side by side in the order of reproduction.
The image information is, for example, a plurality of color still images with a series of transitions. For example, it is a still image in which the landscape is cut frame by frame in units of, for example, 10 m for a certain traveling course that actually exists. However, the next recording information may be audio information instead of one frame of still image.
The audio information is, for example, the sound of murmuring if the still image includes a river, the sound of waves at the coast, the chirping of birds in the forest, or the voice of a person in the city.

Set the CD in the CD-ROM device 10,
When a switch (not shown) is turned on, the CD rotates and the C
The information recorded in D is read by the pickup means in the CD-ROM device 10. In this case, prior to the image information and the sound information, the program information (the information for controlling the reproduction of the image and the sound) recorded before that is read out and read through the CD-ROM interface 11.
Written to AM12. A general-purpose program is stored in the ROM 13 and the microprocessor 14
Reads these programs and controls the playback operation accordingly.

The image information read from the CD-ROM device 10 via the CD-ROM interface 11 is
Since it is digital information that has been decomposed into the three primary colors of light and is compressed, it must be expanded (decoded). Therefore, the read image information is transferred to the image decoding unit 15 and expanded, and then stored in the image memory 16.

On the other hand, when the runner runs on the fixed position running device, the step detection means 17 is executed every time one step is advanced.
Generates a signal. The step detecting means 17 is composed of, for example, a pressure sensor, and outputs “1” when the runner's foot lands, and outputs “0” otherwise. The microprocessor 14 monitors the output of the step detecting means 17,
Every time the output becomes "1", the counter (step counter) in the RAM 12 is counted up to count the number of steps.

For example, the microprocessor 14 sends a command to the CD-ROM device 10 in accordance with a program to read one frame of image information (still image) every time 10 steps (10 m) are counted, with one step being 1 m. CD-ROM
In response to this, the device 10 receives image information (still image) from the CD.
Are sequentially read frame by frame and transferred to the RAM 12 via the CD-ROM interface 11.

The image information once stored in the RAM 12 is
As described above, after being expanded by the image decoding unit 15, transferred to the image memory 16 and converted into an analog value for each of the three primary colors by the D / A converter 18, the television receiver 19 converts it into a color still image. It is projected. That is, every time the runner advances by 10 steps, the still image is sequentially advanced by one frame and displayed on the television receiver 19.

When audio information is recorded after one frame of still image on the CD, the audio information is immediately reproduced. Here, "immediately" means that the image information of one frame is read out subsequently to or after a short time (several seconds).

Further, the fixed position running apparatus is provided with a non-volatile memory 20 as shown in FIG. 1 so that the cumulative running distance according to the number of steps of the runner can be displayed on the television receiver 19. As described above, the step detection means 17
Thus, one step is detected and the counter in the RAM 12 is counted up, and at the same time, the counter in the non-volatile memory 20 is also counted up, for example, with one step as 1 m.
The content of the count is read out as required and displayed on the television receiver 19. It should be noted that it is also possible to store the data for each month and display the transition of the running distance for each month in the form of a graph.

FIG. 2 is a flow chart showing the flow of the above-mentioned operation. Transfer the program in step 50 (C
After transfer from D to RAM 12), image information for one frame is read from the CD in step 51, decoded in step 52, and displayed as a still image in step 53. If the image is not compressed at the time of recording on the CD, decoding is not necessary.

Next, in step 54, step detection and counting are performed, and in step 55 it is determined whether or not the number of steps has reached the set value. When the set value is reached, step 56 determines whether there is image information for the next frame. If yes, the process returns to step 51 to display the image information of the next frame as a still image, and if not, the process ends.

[0020]

According to the present invention, the image information is reproduced as a still image one frame at a time, and each time the runner runs and the number of steps exceeds a preset number of steps, the image information is sent one frame at a time. It suffices to drive a recording medium such as the above at a constant speed, and it can be provided as a fixed-position running device having a traveling course image function with a simple configuration and at a low cost.
