Sensor resolution

If a camera sensor has a resolution of 1080p....how does it take pictures with a higher resolution?

Surely it can't be gaining any more infromation?

Thanks.

Any example camera's?

I think you may be thinking about it the wrong way around. Most (still) cameras have much more resolution than 1080p. However in video mode, the resolution is either down-sampled to give you 1080p, or the camera crops an area of the sensor to give you 1080p.

It up-scales a native 1080p resolution. It is no different than going into photoshop and re-sizing the image. Therefore you are not actually gaining anymore resolution or detail, and the picture may actually look soft at it's larger size, unfortunately that's the joys of marketing.

Excellent - just what I thought, just wanted to confirm!

Thank you very much!

It says in the data sheet - "interpolated". It just upscale the photos.
1080P is about 2MP for reference.
