One of the wonders of 21st-century technology is digital photography.
In 2006 alone, a mind-boggling 72 billion digital photos were taken,
with most of them stored away in computer CPUs and camera memory cards.
One product that has been invented to retain and display these images
and which is finding its way to more and more homes is the digital photo
frame or DPF.
Coming in a variety of sizes, DPFs retains the traditional photo
frame look, but instead of still pictures, they display digital or JPEG
images, MPEG video files, MP3 audio, Internet RSS feeds, and photo
sharing site images, all in slideshow format. Other less common
supported formats include BMP, GIF, PNG or TIFF. They also come in
either wired or wireless format.
DPFs consist of three main parts:
Liquid Crystal Display (LCD) panel - This is the
thin, flat display device that projects the chosen images. Seven-inch or
smaller panels normally use analog thin film transistor (TFT) LCD
panels, while bigger models usually use digital panels with higher
resolution resulting in better picture quality. Available resolutions
usually range from 640 x 480 to 1280 x 1024 pixels, but image quality
decreases as the screen gets larger since the available pixels become
less compact.
Printed Circuit Board (PCB) – This
is where the DPF’s software is stored, which enables use of different
file types and memory cards. Many DPFs pictures come from a camera
memory card, while other pictures can be accessed via a USB connection.
Some DPFs have built-in-memory, but such memory can only allow small
storage amount and is relatively expensive. Also, DPFs with internal
memory allows permanent storage of images that can be displayed/played
even without a memory card. The amount of images that can be stored in a
memory card is also the same for the DPF that utilizes it.
Framing- This is the part of DPFs that adheres
closest to basic photo frame features. While many models are in plastic
or resin, others still utilize the more common wood, metal and chrome.
Some frame styles allow different frame options (known as bezels). Most
DPFs are meant to be placed on a table, desk or counter top, but a few
DPFs can also be hung on a wall.
Ceiva Logic, a company established by former Disney executives in
2000, pioneered in the production of DPFs, which brought about a totally
new market sector. Along with DPFs, Ceiva offered a regular service
plan that allowed customers to share photos. Another pioneer DPF is the
Kodak Smart Picture Frame, which allowed downloading of images via
dial-up connection to the Internet and also regular digital photo
service.
Current DPFs are a lot more sophisticated, allowing a wide variety of
features once considered unlikely. A good example is the MemoryFrame
8104 Premium brand. Its Internet-friendly applications integrate the new
multimedia features of Microsoft Windows Vista and can support other
Windows capabilities such as Media Connect and Connect Now. It also
fully supports the features and capabilities of Windows XP when used
with Windows Media Player 11.
