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.

  • Page 5 Versatility—File upload and video output Most EPSON digital cameras allow you to upload presentations, images, and programs to the camera and then connect the camera directly to a video output device, such as a television, VCR or multimedia projector.
  • Page 6 Page 5 Versatility—Voice recording Several EPSON digital cameras have built-in microphones which allow you to record a voice message for each image, right on the camera. Some cameras also have a built-in speaker so you can also listen to the message right on the camera.
  • Page 7 Optical zoom uses a lens system to magnify image with no loss of image quality. Many EPSON cameras have a 3X optical zoom lens that can be combined with the 2X digital zoom for a maximum 6X zoom. 2. Quick shot—This picture mode saves up to 10 standard, fine, or super fine images in temporary storage while you keep taking pictures.
  • Page 8 (future printers will have this feature, and many current models will have updated drivers available to support it) and the EPSON PhotoPC 3100Z is the first EPSON digital camera to incorporate this technology. PRINT Image Matching offers a solution to several problems when printing digital images: Because software programs set their own unique print commands, it has been difficult to get accurate prints on a consistent basis when printing digital camera images.
