Frame rate=1/(Time per frame)

=1/(Integration time + Readout time)

Integration time:

It is necessary to be changed by the required distance accuracy and usage environment factors such as fluctuating background light.

Readout time=

1

Clock pulse frequency

× Horizontal timing clock × Number of vertical pixels

=Time per clock (Readout time per pixel) × Horizontal timing clocks × Number of vertical pixels

Calculation example of readout time (clock pulse frequency: 5 MHz, horizontal timing clocks: 110, number of vertical pixels: 72)

Readout time=

1

× 110 × 72

=200 [ns] × 110 × 72

=1.584 [ms]
