Add camera ENUM for changing sensor line time vs bit depth #21

Open adamkglaser opened 1 year ago

adamkglaser commented 1 year ago

New finding from camera manufacturer which is important (and could indirectly modulate the line time). The line time of the camera actually depends on the bit depth setting (imposed by the actual Sony IMX411 camera sensor chip build).

eGrabber frame rates are limited as follows, where the line rate can be reverse calculated as:

line rate = 1 / (10760 lines x frame rate) [sec]

bit depth frame rate [hz] line rate [μs] raw data rate [MB/sec] 16-bit packed data rate [MB/sec]
16 2.045174360275268 45.44 618 618
14 4.598678588867187 20.21 1215 1388
12 6.195786952972412 15.00 1403 1871

** Note: the Sony IMX411 sensor has 10640 lines readout per image, but 10760 actual rows which are read (the extra 120 are not output into the image).
