Image Quality—Megapixel CCD sensors
EPSON digital cameras include a one megapixel, two megapixel, or three megapixel CCD sensor, which
determines the resolution of the images. Each megapixel contains one million pixels.
A CCD is made up of an array of photosensors (CCD elements or
photosites) that are able to record a unique image detail. Each
photosensor (or CCD element) creates an electrical charge
proportional to the amount of light it receives and sends the charge to
an A/D (Analog to Digital) converter inside the camera.
Because a higher resolution image contains more detail, you can:
Enlarge an image without losing a significant amount of detail.
Print an image to a high resolution output device (such as an
EPSON Stylus ink jet printer or a printing press)—many
industry analysts believe that the quality of images captured
with two megapixel digital cameras is good enough to replace
traditional film-based cameras.
The key differences between a one megapixel, two megapixel, and three megapixel CCD sensor are:
Ideal use for images
with low compression
One, two, and three megapixel cameras produce excellent 4 x 6-inch and 5x7-inch prints. The key
difference lies in the quality of the image enlargements.
