Digital Camera MegaPixel
Resolution Every camera has a sensor which places an upper limit on just
how much fine detail the camera can capture. The sensors (CDD or CMOS), consist
of a matrix of photosensitive cells manufactured on a silicon chip. The smaller
and the more closely spaced the photosensors, the better the ability to resolve
fine detail. The design and the type of sensor, along with quality of the
camera lens, sets the upper limit on fine detail which is usually termed
image resolution. Other factors such as sensitivity, noise, design of
the image processing software, and image compression, play an important role in
determining the "quality" of the final image. These days cameras boast of 2, 3,
4, 5 or even 6 MegaPixel sensors. While higher megapixel ratings do not
guaranteee higher image quality, they do set the upper limit on the overall
performance of the entire digital camera system. Please keep in mind that
megapixel resolution alone, does not tell the entire story. A particular
camera with a lower megapixel seonsor may in fact produce a noticably higher
quality image than another camera with a higher megapixel count. The amount of
"visual noise" varies from one camera design to another and may depend not only
on the type of image sensor (CCD vs CMOS) but a host of other factors as
already mentioned above.
One indisputable piece of advice is this: Don't bother with a
camera that has less than 2 MegaPixel sensors, but do consider cameras with 2
Megapixel sensors.
Affordable Cost and Excellent
Quality
A number of 2 MegaPixel cameras have excellent
1600x1200 resolution, but may lack sophisticated camera controls. In other
words you have no choice of aperture, exposure timing, or special settings for
portrait, low light, or fast moving sports events. If you do not need these
more "sophisticated features" outstanding cameras in this category are:
