Everybody knows to check how many mega pixels their new camera has. Although more mega pixels does not necessarily mean better photos most people understand why mega pixels are imp...

Image devices with a CCD sensor, such as digital cameras and camcorders, can readily implement an electronic shutter. Such electronic shutter does not require extra circuitry, beca...

CMOS image sensors are widely used in digital still cameras for capturing images. Their competitors are CCDs, accomplishing the same task. We analyze the pros and cons of these two...

The digital cameras megapixels madness is very similar to the personal computer Mhz madness back in the 90s. The number of pixels a camera uses to produce a digital photo is just o...

CCDs and CMOS sensors alike cannot distinguish colors; still our camera takes colored pictures. How can it be? First of all, why can't a CCD detect colors? What happens inside...

In many digital still cameras, the image sensor capturing our photograph in place of the standard film is a CCD (charge-coupled device). How it is manufactured and what happens i...

Ultraviolet-visible spectroscopy continues to be one of the core disciplines practiced in nearly every analytical laboratory. Since its inception by Cary and Beckman in the 1940s, ...

Let me share with you something that happened to me just the other day. I was contacted by a guy named David. He had just purchased a panasonic pv-gs400 3 ccd camcorder and has ...

A CCD, or a Charge Coupled Device, is a microelectronic device used to capture digital images. CCDs can work with several other digital video devices such as scanners, digital cam...
