Abstract

When, after moving to an area having a time difference, a camera-integrated recording-and-reproducing apparatus has been used for taking a video image and recording the taken video image together with date and time information without performing a time-difference correction on an internal clock, date and time information which has been corrected in time difference can be displayed at the time of reproduction of the video image. More specifically, date and time data as reproduced is corrected in time difference on the basis of time-difference correction information corresponding to an area beforehand inputted by a key operation, and the time-difference-corrected date and time data is displayed while being superimposed on the reproduced video image.

Claims

1. A reproducing apparatus comprising:

a reproduction device adapted to reproduce a signal from a recording medium to output the reproduced signal;

an extraction means adapted to extract clock data included in the reproduced signal;

an input device adapted to input correction information to perform a time-difference correction; and

2. A reproducing apparatus according to claim 1, wherein the correction information is an area name, and said correction device holds time-difference information corresponding to the area name.

3. A reproducing apparatus according to claim 1, wherein the correction information is a difference in time between areas.

4. A reproducing apparatus according to claim 1, further comprising a display control device adapted to provide a control to cause a display screen to display the time-difference-corrected clock data.

5. A reproducing apparatus according to claim 1, wherein said correction device cancels the time-difference correction by a key operation performed once, to return the clock data to a state obtained before the time-difference correction.

6. A video camera comprising:

an image pickup device adapted to pick up an object image to output a video signal;

a clock adapted to generate clock data;

a recording and reproducing device adapted to record both the video signal and the clock data on a recording medium and reproduce a signal from the recording medium;

an extraction device adapted to extract the clock data from the signal reproduced from the recording medium;

an input device adapted to input correction information to perform a time-difference correction; and

a correction device adapted to perform the time-difference correction on the extracted clock data on the basis of the inputted correction information.

7. A video camera according to claim 6, wherein the correction information is an area name, and said correction device holds time-difference information corresponding to the area name.

8. A video camera according to claim 6, wherein the correction information is a difference in time between areas.

9. A video camera according to claim 7, further comprising a setting device adapted to set clock data in said clock means and for setting an area name indicating which area the set clock data is based on.

10. A video camera according to claim 6, further comprising a display control device adapted to provide a control to cause a display screen to display the time-difference-corrected clock data.

11. A video camera according to claim 6, wherein said correction device cancels the time-difference correction by a key operation performed once, to return the clock data to a state obtained before the time-difference correction.

12. A computer-readable storage medium which stores therein a program for executing a processing comprising:

a reproduction process of reproducing a signal from a recording medium to output the reproduced signal;

an extraction process of extracting clock data included in the reproduced signal;

an input process of inputting correction information for performing a time-difference correction; and
