Table 8-6 The effective information of each event
Among them: the timestamp is the time when the event occurs, and the timer starts when the camera is
powered on or reset. The bit width of the timestamp is 64 bits, and the unit is ns.
8.6.1.
ExposureEnd Event
If the ExposureEnd Event is enabled, when the camera's sensor has been exposed, the camera sends
out an ExposureEnd Event to the host, indicating that the exposure has been completed.
8.6.2.
BlockDiscard Event
When the average bandwidth of the write-in data is greater than the average bandwidth of the read-out
data, the frame buffer may overflow. If the frame buffer is full and the camera continue to write image data
to it, then the new data will overwrite the previous image data which has been in the frame buffer. At this
moment, the camera sends a BlockDiscard event to the host, indicating that image discard event has
occurred. So, when you read the next frame of image, the image is not continuous.
8.6.3.
BlockNotEmpty Event
When the average bandwidth of the write-in data is greater than the average bandwidth of the readout
