This question already has an answer here:
I took this shot using a Sony Xperia SP with OpenCamera, here are some details:
- Exposure: 1/800
- ISO: 50
- Aperture: f/2.4
- focal length: 3.0
The photo was taken out of a train, at around 160km/h, the truck was moving in the opposite direction with approx. 90km/h.
The distance that the truck moved withing the 1/800th of a second should be somewhere around 10cm (~1/3 foot), but the distortion is clearly higher. It also does not look like it's related to the lens distortion as the it's speed dependent (look at the car and guardrail as a reference).
This looks similar and is caused by line-wise image creation of a crt-tube. Could it be that the sensor is reading the pixels line-wise as well?
Almost forgot the most relevant detail: the shot was taken on the Storebæltsbroen. ;-)
