My problem is when I take a picture (a close one) the straight edge looks a little curved. In a standard camera, like a CyberShot.

I would like to know if there is some relationship between the curvature of the glass and that effect or if you know more information about that.

Yes the image distortions can be mapped and corrected for.
You could do this analytically just from the lens design and the scene - but you would need a detailed optical design for the lens.

The easier way is to take a picture of a calibration target (typically a chess board or array of dots) and then map the distortions in software and apply the same corrections to your image.

See opencv for examples
