Abstract

On an information record medium, there are recorded a plurality of still picture information and information on a transition effect during successive reproduction of the plurality of still picture information. As the transition between still pictures reproduced successively, it is possible not only to perform a normal transition in which after display of one still picture is ended, display of the next still picture is started, but also a cross transition in which the display end of one still picture and the display start of the next still picture can be performed concurrently. During successive reproduction of the still picture information, the transition effect information recorded corresponding to each still picture set is referenced so that each still picture is reproduced so as to produce the transition effect at switching of still pictures.

Claims

1. An information record medium comprising:

plural still picture information; and

transition effect information of each still picture information between plural still picture information to be successively reproduced,

wherein the transition effect information includes;

transition effect kind information indicating a kind of transition effect;

transition effect time information indicating a period of the transition effect; and

cross transition information indicating whether or not to apply a cross transition executing the transition effect between the successive still picture information in parallel in terms of time.

2. The information record medium according to claim 1, wherein the transition time information includes:

start transition effect time information indicating a period of a transition effect at a time of starting a display of the still picture information; and

end transition effect time information indicating a period of a transition effect at a time of ending the display of the still picture information.

3. The information record medium according to claim 1, wherein the cross transition is a process of executing a transition at a time of ending a display of first still picture information and a transition at a time of starting a display of second still picture information to be reproduced subsequently to the first still picture information during a same period.

4. The information record medium according to claim 1, wherein the transition effect information is recorded for each still picture set constructed by the still picture information to be successively reproduced, and the cross transition information is identically defined for all the transitions between the plural still picture information included in the still picture set.

5. The information record medium according to claim 1, further comprising playlist information defining a reproduction sequence of the plural still pictures,

wherein the transition effect information is included in the playlist information.

8. An information reproduction apparatus which reproduces the information record medium according to claim 1, comprising:

a reading unit which reads the plural still picture information and the transition effect information from the information record medium; and

a reproduction unit which controls presence or absence of application of the cross transition in accordance with the transition effect information and reproduces the plural still pictures.

9. An information reproduction method which reproduces the information record medium according to claim 1, comprising:

a reading process which reads the plural still picture information and the transition effect information from the information record medium; and

a reproduction process which controls presence or absence of application of the cross transition in accordance with the transition effect information and reproduces the plural still pictures.

13. A computer program product in a computer-readable medium executed by an information reproduction apparatus comprising a computer, the computer program product making the computer function as:

a reading unit which reads the plural still picture information and the transition effect information from the information record medium according to claim 1;

and

a reproduction unit which controls presence or absence of application of the cross transition in accordance with the transition effect information and reproduces the plural still pictures.

6. An information record apparatus comprising:

a first record unit which records plural still picture information on an information record medium; and

a second record unit which records, on the information record medium, transition effect information of each still picture information between plural still picture information to be successively reproduced,

wherein the transition effect information includes;

transition effect kind information indicating a kind of transition effect;

transition effect time information indicating a period of the transition effect; and

cross transition information indicating whether or not to apply a cross transition executing a transition effect between the successive still picture information in parallel in terms of time.

7. An information record method comprising:

a first record process which records plural still picture information on an information record medium; and

a second record process which records, on the information record medium, transition effect information of each still picture information between plural still picture information to be successively reproduced,

wherein the transition effect information includes;

transition effect kind information indicating a kind of transition effect;

transition effect time information indicating a period of the transition effect; and

cross transition information indicating whether or not to apply a cross transition executing the transition effect between the successive still picture information in parallel in terms of time.

10. An information record reproduction apparatus comprising:

a first record unit which records plural still picture information on an information record medium;

a second record unit which records, on the information record medium, transition effect information including transition effect kind information indicating a kind of transition effect, transition effect time information indicating a period of the transition effect and cross transition information indicating whether or not to apply a cross transition executing the transition effect between successive still picture information in parallel in terms of time, for each still picture information between the plural still picture information to be successively reproduced;

a reading unit which reads the plural still picture information and the transition effect information from the information record medium; and

a reproduction unit which controls presence or absence of application of the cross transition in accordance with the transition effect information and reproduces the plural still pictures.

11. An information record reproduction method comprising:

a first record process which records plural still picture information on an information record medium;

a second record process which records, on the information record medium, transition effect information including transition effect kind information including a kind of transition effect, transition effect time information indicating a period of the transition effect and cross transition information indicating whether or not to apply a cross transition executing the transition effect between successive still picture information in parallel in terms of time, for each still picture information between the plural still picture information to be successively reproduced;

a reading process which reads the plural still picture information and the transition effect information from the information record medium; and

a reproduction process which controls presence or absence of application of the cross transition in accordance with the transition effect information and reproduces the plural still pictures.

12. A computer program product in a computer-readable medium executed by an information record apparatus comprising a computer, the computer program product making the computer function as:

a first record unit which records plural still picture information on an information record medium; and

a second record unit which records, on the information record medium, transition effect information of each still picture information between plural still picture information to be successively reproduced,

wherein the transition effect information includes transition effect kind information indicating a kind of transition effect, transition effect time information indicating a period of the transition effect, cross transition information indicating whether or not to apply cross transition executing the transition effect between the successive still picture information in parallel in terms of time.
