Frame Rate: The number of decode attempts in a given amount of time.
Decode Try Time:
The speed of decoding a given symbol. The time of decoding is dramatically
affected by the number of attempts at decoding images (frame speed) available. An attempt includes
the time used in the photographic exposure of an image, and includes the transfer of the image to the
CPU and the time taken to analyze the image, locate a symbol, and decode the symbol into data or
abandon the attempt because no data could be derived.
