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.

▼

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.

The key differences between a one megapixel, two megapixel, and three megapixel CCD sensor are:

▼

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.

Technical Brief—Digital cameras Page 2 Image Quality—HyPict™ Image Enhancement Technology Many digital cameras use an interpolation method to produce images with higher resolution than the camera's CCD can capture. EPSON HyPict image enhancement technology uses an exclusive interpolation method. EPSON HyPict image enhancement technology produces more accurate results because it applies image enhancement before JPEG compression.

Technical Brief—Digital cameras Page 3 Image Quality—EPSON ClearOptics™ glass lens EPSON digital cameras all use an EPSON ClearOptics glass lens, but the specific type of lens differs by camera model. For example, the lens on the low-end model may include an aspherical glass lens with five elements in four groups, while the high-end model may include eight elements in seven group construction using two aspherical Sharp edge lenses.

Technical Brief—Digital cameras 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. 1. To record a message—You can record a message immediately after shooting a photo, or, in some cases, add it later while the image is still in the camera. Recordings are saved with the image in .WAV format.
