What Is Dye-sublimation Printing? > 자유게시판

All of us have at the least one technologically challenged relative. We will e-mail images or publish them on a private Internet page for a few of our cherished ones, however there are others who need nothing to do with a computer, not to mention the Web. The proper gadget for sharing pictures with the computerless is the digital picture body. This is a system about the scale and form of an ordinary image body. It contains an LCD display, which shows multiple photographs in a slideshow format, and it connects to the Web by way of telephone line to download new footage and information to display on the display screen. The frames are fairly comparable in development, although they do supply some totally different options. In this edition of HowStuffWorks, we'll take a look at the Ceiva Digital Photograph Receiver. Before we get into exactly how it really works, let's see what it does. The thought is that a person who does have a computer, a digital camera and pc abilities buys the frame, units up the account and passes it on.

Once the account is set up, you (the individual with the pc) add photos to the Ceiva Internet site. Each night, the digital image frame (within the computerless particular person's home) uses the cellphone line to connect to the Ceiva servers and obtain any new photos. It's also possible to control all the frame's settings via the web site. It has most of the same elements as the computer on your desktop, but they're loads simpler within the frame because they solely have to carry out a single task. The central processing unit (CPU) within the Ceiva digital image frame is similar to the type used in small, electronic handheld video games. Essentially the most processor-intensive process carried out by this CPU is downloading photos from the online site. The remainder of the time, it would not break a sweat. It also has some Flash memory, which is where the photographs, settings and among the operating software program stay.

Each forms of memory are persistent -- no information is misplaced if the unit is unplugged. The body has a 33.6-Kbps modem, which it makes use of to connect with the Web and download the new photos you put up. The display is a 640x480-pixel, passive-matrix liquid crystal show (LCD) with a viewing area of about 5 by 7 inches (13 by 18 cm). This kind of display is thin sufficient that the digital frame isn't a lot thicker than an atypical picture body. The photographs are displayed in 12-bit shade, which means that approximately 4,a hundred completely different colors may be presented on the screen. The only user-operated controls on the frame are a black button, which adjusts the brightness of the show, and a white button that turns the frame on when the person first plugs it in and will also be used to manually dial in. The Ceiva body uses an embedded operating system called PSOS.

This working system is designed for devices like PDAs, electrical-testing gear and set-prime bins. Let's check out how the Ceiva body works. If the consumer presses and holds the white button on the again of the frame, MemoryWave it dials up and connects to the Web. The $50-per-yr fee for the Ceiva service includes access to the Web by the use of an area cellphone number. The connection to the Internet is used solely to obtain the brand new photographs and settings to the body. There is no interactivity, no Net access and no e-mail. The machine is designed to behave like an image body, not a computer. As soon as logged on, the frame compares the images already on the frame to the ones ready to be sent, Memory Wave downloading any new ones. It also downloads any new settings. When it's completed downloading, the frame hangs up the cellphone line and begins displaying the new images one after another.
