Fixed Pattern Noise (FPN), Photo Response Non Uniformity (PRNU), stuck pixels, read noise and thermal noise are an inherent part of the sensor.

    3.2.3 Timing, Performance and Data Rates The PL-A780 sensor uses a 40 MHz pixel clock to read out pixel data at 25 nanoseconds per pixel. Each row also has a delay of 7.3 µseconds and is padded with 10 isolation pixels. The minimum row readout time, in microseconds, is given by ∗...

  • Page 21: Figure 7 Rolling Shutter Integration And Read-Out

    The distortion is due to the comparatively lengthy process of readout compared to exposure. For example, to readout the entire PL-A780 frame requires approximately 250 milliseconds. While a short exposure may stop a moving object, the same object can move appreciably in the quarter second that it takes to readout the frame resulting in distortion in the direction of motion.
