6. Memory Management

Selecting the sensor architecture allows the user to choose a recording method suited to their needs. The user can select the maximum frame rates based on the required spatial resolution. The images generated by the sensor are then transferred for storage in memory. Two types of memory are used in high-speed imaging: internal memory storage and external memory storage after transferring the image area to an external storage medium. The amount of data to be transferred is directly proportional to the number of bits per pixel, the number of pixels per image… and the number of frames per second. Some manufacturers use terms like Mpix/s or Gpix/s; the transfer rate is then calculated by multiplying this value by the pixel size in bytes (1 byte = 8 bits; "o" in French, "B" in English).
