Like a film camera, a camcorder "sees" the world through lenses. In a film camera, the lenses serve to focus the light from a scene onto film treated with chemicals that have a controlled reaction to light. In this way, camera film records the scene in front of it: It picks up greater amounts of light from brighter parts of the scene, and lower amounts of light from darker parts of the scene. The lens in a camcorder also serves to focus light, but instead of focusing it onto film, it shines the light onto a small semiconductor image sensor. This sensor, a charge-coupled device (CCD), measures light with a half-inch (about 1 cm) panel of 300,000 to 500,000 tiny light-sensitive diodes calledphotosites.
Each photosite measures the amount of light (photons) that hits a particular point, and translates this information into electrons (electrical charges): A brighter image is represented by a higher electrical charge, and a darker image is represented by a lower electrical charge. Just as an artist sketches a scene by contrasting dark areas with light areas, a CCD creates a video picture by recording light intensity. During playback, this information directs the intensity of a television's electron beam as it passes over the screen.
Most digital thermometers use liquid crystal displays that cannot be repaired.
Std. transmission could be "shift" light
You will have an image about 20% larger at x60, but there is catch. Usually magnification of that amount is a combination of the optical zoom and digital zoom. The total obtained by multiplying. With digital zoom, the quality will likely decrease faster as the magnification increases. So normally, the optical zoom will go to maximum before the digital zoom begins to operate.
So if the x50 has 10x optical and then 5x digital, it could produce a better image than 6x optical with 10x digital zoom (unless the optics are not that great). It's good to know which is which. See if you can find reviews on both.
