Abstract

A disclosed system includes: a slow-motion image detection unit 10 for detecting a portion of a slow-motion image from an image signal; a recording unit 11 for recording on a recording medium 1 an image signal and information of a slow-motion image obtained from the slow-motion image detection unit 10; a reproduction unit 12 for reproducing the recording medium 1 in which the image signal and the information of the slow-motion image are stored; and a reproduction control unit 13 for controlling the reproduction unit 12. In recording, after the image signal is tele-recorded ordinarily, the information of the slow-motion image is recorded in a predetermined area on the recording medium 1, while in reproduction, after the slow-motion image information is reproduced and stored first, the image signal is reproduced. The reproduction is possible in a variety of modes.

Claims

1. A recording medium for recording an image signal, comprising:

a first recording area for recording the image signal; and

a second recording area for recording information related to a slow-motion image signal contained in the image signal.

2. The recording medium according to claim 1, wherein the second recording area comprises:

an area for recording a recording position of the slow-motion image signal;

an area for recording a recording time lapse of the slow-motion image signal;

an area for recording a reproduction rate of the slow-motion image signal; and

an area for recording a still picture related to the slow-motion image signal.

3. The recording medium according to claim 2, wherein the second recording area further comprises an area for recording a recording position of an image signal which provides an original of the slow-motion image signal and is obtained from a recording time lapse of the slow-motion image signal and a reproduction rate of the slow-motion image signal.

4. The recording medium according to claim 1, wherein the recording medium is a disk-shaped medium.

5. An image recording apparatus for recording an image signal on a recording medium, comprising:

an image signal recording device which records the image signal on the recording medium;

a slow-motion image detection device which detects a slow-motion image signal contained in the image signal;

a slow-motion recording position detection device which detects a recording position of the slow-motion image signal detected by the slow-motion image detection device;

a slow-motion recording position recording device which records a recording position detected by the slow-motion recording position detection device;

a recording time lapse recording device which records a recording time lapse of the slow-motion image signal;

a reproduction rate detection device which detects a reproduction rate of the slow-motion image signal; and

a still picture recording device which records a still picture related to the slow-motion image signal.

6. The image recording apparatus according to claim 5, wherein the image recording apparatus comprises an operation device which obtains a recording time lapse of an image signal which provides an original of the slow-motion image signal, from a recording time lapse of the slow-motion image signal and a reproduction rate of the slow-motion image signal.

7. The image recording apparatus according to claim 6, wherein the image recording apparatus further comprises an original signal recording position recording device which records, based on a recording time lapse of an image signal which provides an original of the slow-motion image signal obtained by the operation device, a recording position of the original image signal.

8. The image recording apparatus according to claim 5, wherein 110 a recording position of the slow-motion image signal, a recording time lapse of the slow-motion image signal, a reproduction rate of the slow-motion image signal, a recording position of an image signal which provides an original of the slow-motion image signal, and a still picture related to the slow-motion image signal are recorded in a predetermined area on the recording medium after the image signal is recorded.

9. The image recording apparatus according to claim 5, wherein the slow-motion image signal is determined on the basis of inter-field correlation of image data.

10. The image recording apparatus according to claim 5, wherein the slow-motion image signal is determined on the basis of the number of blocks that are recognized to be of a slow-motion image signal, a field being divided into a plurality of blocks beforehand to obtain inter-field correlation of picture data for each of the blocks.
