Abstract
Image data is captured by a digital still camera at a rate characterized as slow video. The slow video data stream is slow enough that relatively slow memory can be utilized for on-the-fly storage of the slow video data stream. Audio data is recorded at the same time that image data is recorded at a slow video data rate, thereby accompanying the images collected in slow video mode. Synchronization markers are stored with the audio data, where each synchronization marker is associated with a single frame of the stored video data. As the audio data is played back, an individual video frame is retrieved and displayed when the corresponding synchronization marker is encountered.
Claims19
A method for capturing images, comprising:
- providing a digital still camera having a memory;
- capturing audio data substantially continuously, wherein said audio data forms an audio data stream;
- capturing a video frame;
- waiting for an interval;
- and
- repeating said capturing said video frame and said waiting, wherein said captured video frames form a video data stream.
A method for replaying stored video frames and audio data, the audio data including at least one synchronization marker associated with a stored video frame, the method comprising:
- playing back said audio data;
- detecting a synchronization marker;
- and
- displaying the particular stored video frame corresponding to said detected synchronization marker.
A digital still camera, comprising:
- an image acquisition device;
- a controller electrically connected to said image acquisition device, wherein a video data stream passes through said controller at a maximum bit rate;
- and
- first memory electrically connected to said controller, said first memory having a maximum data acceptance rate, wherein said maximum bit rate of said video data stream is no greater than said maximum data acceptance rate of said memory.
