Abstract
A method of processing digital video data comprises continuously capturing digital video data representing image frames. While capturing the digital video data, the digital video data is encoded into a sequence of encoded image frames, the sequence comprising key frames and delta frames, and storing the sequence of encoded image frames. It is then determined that the stored sequence of encoded image frames is to be entropy coded and, as a consequence, entropy coding the sequence of encoded image frames into an entropy coded sequence of image frames and storing the entropy coded sequence of image frames.

A method, performed in an image capturing device, of processing digital video data, the method comprising:
- continuously capturing digital video data representing image frames;
- while capturing the digital video data, encoding the digital video data into a sequence of encoded image frames, the sequence comprising key frames and delta frames, and storing the sequence of encoded image frames;
- determining that the stored sequence of encoded image frames is to be entropy coded and, as a consequence, entropy coding the sequence of encoded image frames into an entropy coded sequence of image frames and storing the entropy coded sequence of image frames, wherein the determining that the stored sequence of encoded image frames is to be entropy coded is based on receiving a triggering signal, and wherein the reception of the triggering signal comprises receiving a signal that is indicating that the image capturing device is operating under external power.
An image capturing device comprising circuitry configured to:
- continuously capture digital video data representing image frames;
- while capturing the digital video data, encode the digital video data into a sequence of encoded image frames, the sequence comprising key frames and delta frames, and store the sequence of encoded image frames;
- determine that the stored sequence of encoded image frames is to be entropy coded and, as a consequence, entropy code the sequence of encoded image frames into an entropy coded sequence of image frames and store the entropy coded sequence of image frames, wherein the circuitry is configured such that:
- the determining that the stored sequence of encoded image frames is to be entropy coded is based on receiving a triggering signal that is indicating that the image capturing device is operating under external power.
