Abstract
Image data (still image data) is encoded to create video data. When an interval recording mode is set, a plurality of video data created by an encoder (image compressor 42) are merged, and the merged video data is recorded as a single interval video data. In the interval recording mode, power supply to the encoder is stopped every time an encoding process of the image data is completed. After the stop of the power supply to the encoder, the power supply to the encoder is resumed when an encoding process of the next image data needs to be performed. Continuity information is managed during the stop of the power supply to the encoder. The continuity information is necessary for creating the plurality of video data so that the interval video data constitutes a stream that can be reproduced continuously.
Claims12
An imaging apparatus comprising:
- an image sensor configured to pick up an image of a subject;
- an image processor configured to process an output of the image sensor to generate processed image data;
- an encoder configured to encode the image data to create video data;
- a recording mode selector configured to set a recording mode of the imaging apparatus to an interval recording mode, in which a frequency at which the video data is created is lower than a frequency in an ordinary recording mode;
- a recorder configured to merge a plurality of the video data created by the encoder, and to record the merged video data as a single interval video data, in the interval recording mode;
- a power controller configured to stop supplying power to the encoder after a creating process of the video data is completed, and to resume supplying power to the encoder when a creating process of the next video data needs to be performed, in the interval recording mode;
- and
- a continuity information manager configured to manage continuity information during the stop of the power supply to the encoder, the continuity information being information to be used to allow the interval video data to constitute a stream that can be reproduced continuously, and being referred to by the encoder when the encoder creates the video data.
