High-speed image sequence recording is a diverse technology used in many application areas including vehicle crash testing, high-speed process and machinery diagnostics and for recording and evaluating complex procedures in medical applications. It is also used for statistical evaluation in sports, and for high-speed action scenes in film making.
There are two types of high-speed recording solutions, on-line and offline. On-line systems rely on high-speed cameras sending data directly to a PC's system memory or disk capacity, while off-line solutions contain the image recording memory within the camera itself. Both solutions have advantages and disadvantages and the decision is normally driven by the required frame rate.
On-line systems rely on the interface speed between the camera and the computer and the speed of the computer. Using the fastest current interfacing technology (status 01/2015) this is limited to roughly 4 GB/s. If this speed is acceptable and you require long sequences this solution is a good choice.
Off-line systems increase this throughput as images are held in the camera without any need for transmission while recording, however, these systems are normally limited to 16 GB or 32 GB of memory, reducing the maximum possible recording length.
A new approach for a different storage concept using a solid-state storage device (SSD) in the camera allows image data rates to increase massively. This means that high frame rates combined with high resolution for high-performance slow-motion and high-speed cameras are now possible. This new data management provides camera-internal data transfer at 1300 MB/s. That is six times the data speed compared to conventional storage concepts.
