Abstract

A recording apparatus is disclosed. The recording apparatus includes a data input portion configured to input data, a first moving image signal recording portion configured to record, based on the input data, a first moving image signal having a first image quality attribute, a condition detector configured to detect that the input data satisfies a predetermined condition during recording of the first moving image signal, and a second moving image signal recorder configured to record, based on the input data, a second moving image signal having a second image quality attribute when the condition detector detects that the input data satisfies the predetermined condition.

Claims

1. An apparatus comprising:

processing circuitry configured to

generate a plurality of second moving image signal segments, each segment corresponding to a respective section of a first moving image signal, each respective section being a part of a first moving image having a predetermined feature, an image quality attribute of each segment of the second moving image signal being different from the corresponding section of the first moving image signal, and wherein each frame included in the segment of the second moving image signal represents data included in each corresponding frame of the corresponding section of the first moving image signal in its entirety, such that the processing circuitry generates the plurality of second moving image signal segments, each frame of which includes an entire image from each corresponding frame of the corresponding section of the first moving image signal, but at a different image quality attribute, in response to detecting the predetermined feature in the first moving image, and

associate each segment of the second moving image signal with the corresponding section of the first moving image signal.

2. The apparatus according to claim 1, wherein the predetermined feature is face image data.

3. The apparatus according to claim 1, wherein the predetermined feature is audio data.

4. The apparatus according to claim 1, wherein the processing circuitry is configured to continuously generate the plurality of second moving image signal segments while the first moving image signal has the predetermined feature.

5. The apparatus according to claim 1, wherein

the processing circuitry is configured to continuously generate the plurality of second moving image signal segments for a predetermined time period starting from when the first moving image signal has the predetermined feature.

6. The apparatus according to claim 1, wherein the processing circuitry is further configured to record the first moving image signal and the plurality of second moving image signal segments.

7. The apparatus according to claim 6, wherein the first moving image signal and the plurality of second moving image signal segments are recorded separately in different folders.

8. The apparatus according to claim 6, wherein

the processing circuitry is further configured to record management information that indicates association between the second moving image signal segments and a respective record position thereof in the first moving image signal.

9. The apparatus according to claim 8, wherein the record position is represented by time information of the first moving image signal.

10. The apparatus according to claim 1, wherein the image quality attribute of the corresponding section of the first moving image signal has a higher image quality than the corresponding segment of the second moving image signal.

11. The apparatus according to claim 1, wherein the image quality attribute of the corresponding section of the first moving image signal has a lower image quality than the corresponding segment of the second moving image signal.

12. The apparatus according to claim 1, wherein the image quality attribute of the corresponding section of the first moving image signal has a higher bit rate than the corresponding segment of the second moving image signal.

13. The apparatus according to claim 1, wherein the image quality attribute of the corresponding section of the first moving image signal has a lower bit rate than the corresponding segment of the second moving image signal.

14. The apparatus according to claim 1, wherein the image quality attribute of the first moving image signal is HD format.

21. The apparatus according to claim 1, wherein the processing circuitry is further configured to

generate a button to be displayed on a display panel of the apparatus, the button indicating availability of the image quality attribute associated with the segment of the second moving image signal.

15. A method of recording data, comprising:

generating, by processing circuitry, a plurality of second moving image signal segments, each segment corresponding to a respective section of a first moving image signal, each respective section being a part of a first moving image having a predetermined feature, an image quality attribute of each segment of the second moving image signal being different from the corresponding section of the first moving image signal, and wherein each frame included in the segment of the second moving image signal represents data included in each corresponding frame of the corresponding section of the first moving image signal in its entirety, such that the generating generates the plurality of second moving image signal segments, each frame of which includes an entire image from each corresponding frame of the corresponding section of the first moving image signal, but at a different image quality attribute, in response to detecting the predetermined feature in the first moving image; and

associating, by the processing circuitry, each segment of the second moving image signal with the corresponding section of the first moving image signal.

16. The method of claim 15, further comprising:

continuously generating, by the processing circuitry, the plurality of second moving image signal segments, white the first moving image signal has the predetermined feature.

17. The method of claim 15, wherein the predetermined feature is one of face image data and audio data.

18. The method of claim 15, wherein the first moving image signal and the plurality of second moving image signal segments are recorded in distinct recording mediums.

19. A non-transitory computer readable medium including computer executable instructions that, when executed by a computer, cause the computer to execute a method of recording data, the method comprising:

generating a plurality of second moving image signal segments, each segment corresponding to a respective section of a first moving image signal, each respective section being a part of a first moving image having a predetermined feature, an image quality attribute of each segment of the second moving image signal being different from the corresponding section of the first moving image signal, and wherein each frame included in the segment of the second moving image signal represents data included in each corresponding frame of the corresponding section of the first moving image signal in its entirety, such that the generating generates the plurality of second moving image signal segments, each frame of which includes an entire image from each corresponding frame of the corresponding section of the first moving image signal, but at a different image quality attribute, in response to detecting the predetermined feature in the first moving image; and

associating each segment of the second moving image signal with the corresponding section of the first moving image signal.

20. The non-transitory computer readable medium of claim 19, further comprising:

continuously generating the plurality of second moving image signal segments, while the first moving image signal has the predetermined feature.
