What Is Dye-sublimation Printing
We all have at the very least one technologically challenged relative. We are able to e-mail images or put up them on a private Net page for a few of our beloved ones, however there are others who need nothing to do with a computer, not to mention the Internet. The proper gadget for sharing images with the computerless is the digital picture body. This can be a gadget about the scale and shape of an strange picture frame. It accommodates an LCD screen, which shows a number of photos in a slideshow format, and it connects to the Web via phone line to download new pictures and Memory Wave data to show on the screen. The frames are pretty similar in construction, although they do supply some completely different features. In this edition of HowStuffWorks, we'll have a look at the Ceiva Digital Photo Receiver. Earlier than we get into precisely how it works, let's see what it does. The idea is that a person who does have a pc, a digital camera and pc skills buys the body, sets up the account and passes it on.
As soon as the account is set up, you (the particular person with the pc) add photographs to the Ceiva Web site. Each night time, the digital image frame (in the computerless person's home) makes use of the cellphone line to connect to the Ceiva servers and obtain any new pictures. You may also control the entire frame's settings via the web site. It has most of the same components as the computer in your desktop, but they're quite a bit simpler within the frame as a result of they only have to carry out a single process. The central processing unit (CPU) within the Ceiva digital image frame is similar to the kind utilized in small, digital handheld games. The most processor-intensive task carried out by this CPU is downloading footage from the net site. The remainder of the time, it does not break a sweat. It additionally has some Flash Memory Wave Audio, which is where the photographs, settings and a few of the working software reside.

Each forms of memory are persistent -- no data is misplaced if the unit is unplugged. The frame has a 33.6-Kbps modem, which it makes use of to connect to the Web and obtain the new photos you publish. The show is a 640x480-pixel, passive-matrix liquid crystal show (LCD) with a viewing space of about 5 by 7 inches (thirteen by 18 cm). The sort of display is skinny sufficient that the digital frame is not a lot thicker than an strange image body. The pictures are displayed in 12-bit coloration, which signifies that approximately 4,one hundred totally different colors can be introduced on the screen. The one consumer-operated controls on the body are a black button, which adjusts the brightness of the show, and a white button that turns the frame on when the user first plugs it in and will also be used to manually dial in. The Ceiva frame uses an embedded working system called PSOS.
This working system is designed for Memory Wave Audio units like PDAs, electrical-testing gear and set-high bins. Let's check out how the Ceiva frame works. If the user presses and holds the white button on the back of the body, it dials up and connects to the Web. The $50-per-12 months fee for the Ceiva service consists of access to the Internet by way of a neighborhood telephone number. The connection to the Internet is used only to obtain the brand new pictures and settings to the frame. There is no such thing as a interactivity, no Net entry and no e-mail. The system is designed to behave like a picture frame, not a computer. Once logged on, the body compares the photographs already on the frame to those ready to be sent, downloading any new ones. It also downloads any new settings. When it is finished downloading, the body hangs up the telephone line and starts displaying the brand new photos one after another.
