FPGA timing for example is critical, you have jitter and damping. And with higher temperature you have timing violations. We see on very hot cameras these effects. To prevent, you have a CRC and an extra clock or sync channel. Also embedded data.<br /><br />- The image with a faulty vertical address coding in the sensor will not be possible. Why? Typically with the automotive AR0134/AR0135 sensors and 99% of all the others, you have a destructive readout. You can't readout the same image areas twice. That would be a nice feature, because then you can average identical images by multiple readout and drop the noise by math.Dana Diezemannhttp://www.ids-imaging.comnoreply@blogger.com
