It is important to consider the ways that the standard DSLR is Bandwidth limited. Just like in the slides that discuss how a mobile processor can run at overly hot temperatures for short periods of time, cameras can take bursts of pictures in a short period of time, but will need to take a break once their initial data buffer is full, because it takes much more time to transfer the data to the main memory on the device than to transfer the image data from the sensor to the initial data buffer.

Also, as was mentioned in class, this type of buffering issue is the reason that slow motion cameras in phones have a limit to the amount of time that can be spent recording.

We could probably fix the slow motion problem by expanding the bandwidth capabilities, but that may require us to compromise on other parameters, such as storage capacity.

For anybody interested, Nikon 7000 uses Expeed 2 image processor:

Here are the popular image processors in cameras:

This limitation does not only apply to stills – you can only tape a video for so long before the buffer runs out and you must wait before continuing to film. Another factor to consider is the data transfer badnwidth between the camera image processor and the removable storage. On my D7000, this can be mitigated by using both the SD card slot and the CF card slot. As CF is much faster than SD, I tell the camera to save my videos onto my CF card so I can film uninteruppted.
