The characteristic VERTICAL (often violet) light streak that you see when pointing the camera at very bright sources of light is called 'blooming.'
Blooming occurs when the electrical charge in a pixel exceeds the saturation level (due to very bright light) and the charge starts to fill adjacent pixels in the camera's digital imaging sensor. Typically CCD sensors are designed to allow for easy VERTICAL shifting of the charge but potential barriers are created to reduce flow into horizontal pixels. Hence the excess charge will preferentially flow into the nearest VERTICAL neighbors, resulting to blooming.
Recording the image (as a still picture) is a different matter, for it occurs only at a very short period of time, usually at a fraction of a second, and does not get a continuous light reading (unlike when recording video). Therefore, there is no saturation of the pixel charge. This is the reason why the vertical violet streak (blooming) DOES NOT APPEAR in the recorded image of your pictures, but does, indeed, appear when taking video clips.

Blooming is an inherent characteristic of Charge Coupled Device (CCD) sensors, which is the type used in the GE X5 / X500, and is something that GE X5 / X500 users would have to live with. Cameras, such as most of the dSLRs, make use of CMOS sensors, which are, by their nature, immune to blooming.
