Hi Team,

Customer now use 953 in 1080p 30fps application.

When using single exposure, it works normally.

When using three exposures, it works abnormally.

I think it is because the data rate is beyond 953.

As for three exposures 1080p 30fps, do we have device could support?

Hello Amilie,

This actually depends on the output format from the image sensor. If the sensor does HDR combining internally then there is less data coming out. Because all exposures from pixels are combined before sending out. In case of a linear mode or line by line mode, all exposures can be send out separately. This increases the data rate.

So, you need to consult the Image sensor manufacturer to get the exact throughput.
