Distance area image sensor
S11963-01CR
Calculation method of frame rate
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
× Horizontal timing clock × Number of vertical pixels
Clock pulse frequency
=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: 208, number of vertical pixels: 128)
Readout time=
1
× 208 × 128
5 × 10⁶ [Hz]
=200 [ns] × 208 × 128
=5.324 [ms]
When operating in non-destructive readout mode:
Time per frame = Integration time + (Readout time × Non-destructive readout count)
It is possible to read out only the signal level without reading out the rest level signal. However, noise will increase because the pixel reset
noise cannot be removed. Sensitivity variations in the photosensitive area will also increase because the fixed pattern noise in each pixel
cannot be removed either.
