We all have not less than one technologically challenged relative. We are able to e-mail images or put up them on a personal Web page for some of our liked ones, however there are others who want nothing to do with a pc, not to mention the Internet. The right gadget for sharing pictures with the computerless is the digital image frame. It is a device about the dimensions and shape of an bizarre image body. It contains an LCD display, which shows a number of photographs in a slideshow format, and it connects to the Internet via cellphone line to obtain new photos and data to display on the display screen. The frames are pretty related in construction, although they do provide some different options. In this version of HowStuffWorks, we'll have a look on the Ceiva Digital Picture Receiver. Earlier than we get into precisely how it really works, let's see what it does. The concept is that a person who does have a computer, a digital digital camera and pc expertise buys the body, units up the account and passes it on.

As soon as the account is set up, Memory Wave App you (the person with the computer) add pictures to the Ceiva Net site. Every evening, the digital picture body (within the computerless person's house) makes use of the telephone line to hook up with the Ceiva servers and obtain any new pictures. You can also management all of the frame's settings via the net site. It has most of the identical elements as the computer on your desktop, but they're rather a lot simpler within the frame as a result of they solely must perform a single activity. The central processing unit (CPU) in the Ceiva digital picture body is much like the type used in small, digital handheld video games. Essentially the most processor-intensive task performed by this CPU is downloading photos from the net site. The remainder of the time, it doesn't break a sweat. It also has some Flash Memory Wave, which is where the pictures, settings and a few of the working software dwell.

Each sorts of Memory Wave App are persistent -- no information 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 brand new photos you submit. The show is a 640x480-pixel, passive-matrix liquid crystal display (LCD) with a viewing space of about 5 by 7 inches (13 by 18 cm). The sort of display is skinny enough that the digital body isn't a lot thicker than an strange image body. The pictures are displayed in 12-bit shade, which implies that approximately 4,100 different colours could be presented on the screen. The only person-operated controls on the body are a black button, which adjusts the brightness of the show, and a white button that turns the body on when the user first plugs it in and can also be used to manually dial in. The Ceiva frame uses an embedded working system known as PSOS.

This operating system is designed for devices like PDAs, electrical-testing equipment and set-top containers. 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-yr fee for the Ceiva service includes access to the Internet by means of a local cellphone number. The connection to the Web is used solely to download the brand new pictures and settings to the body. There isn't a interactivity, Memory Wave Program no Web access and no e-mail. The gadget is designed to behave like an image body, not a computer. As soon as logged on, the frame compares the pictures already on the body to those waiting to be despatched, downloading any new ones. It also downloads any new settings. When it's completed downloading, the body hangs up the cellphone line and starts displaying the new photos one after another.
