Scientists know that its actually Mercury reflecting too much light, causing the camera's CCD (" charge-coupled device ") to become oversaturated.

但科学家知道，那只是因为水星反射了过多的阳光，而超过了照相机CCD的负荷所造成的假象。

Apart from the arrival of less pricey full-frame digital SLRs, the other recent development that has impressed your correspondent is the way imaging chips are migrating from CCD (charge-coupled device) technology to CMOS (complementary metal-oxide semiconductor), used widely in the computer industry.

The key difference is that instead of focusing the light on a strip of photochemical film as in traditional cameras, digital cameras use an image sensor, called a charge coupled device (CCD), to capture the image.
