Fig.: 5-16: strobe control in global reset mode
In Global Reset Mode flash is starting together with exposure, all CMOS lines are
sensitive to light. Flash time has to be shorter than exposure time. Exposure time
is determined by flash time.
INFO Strobe control jitter might be visible in the image as brightness instabilities.
We recommend using the very stable integrated I/O flash control for light control.
Precision is about 1 tic or 15ns.
5.1.11 Exposure
l
For various exposure and timing modes in chapter, see "Basic capture
modes" on page 59 .
l
For combining various exposure timings with PWM LED illumination, refer to
"Sequencer" on page 79 .
Setting exposure time
Exposure time can be set by width of the external or internal triggers or pro-
grammed by a given value.
5.1.12 Exposure speed
Frames per second, or frame rate describes the number of frames output per
second (1/ frame time). Especially GigE and USB cameras cannot guarantee pre-
dictable maximum frame rates with heavy interface bus load.
Maximum frame rate might depend on:
l
Pixel clock
l
Image size
l
Tap structure
l
Data transport limitation
l
Processing time
