A digital photo frame is a picture frame that displays digital photos without the need to print them or use a computer. The digital photo frame may also be able to display the photos on a TV set.
Some digital photo frames can only display JPEG pictures. Most digital photo frames display the photos as a slideshow and usually with an adjustable time interval. They also can send photos to the printer.
However, others support additional multimedia content, including movie clips recorded in a digital camera\'s movie mode, MPEG video files and/or MP3 audio.
Certain frames can also load pictures over the Internet from RSS feeds, photo sharing sites such as Flickr, Picasa and from e-mail. Such networked models usually support wireless (802.11) connections.
Digital photo frames typically display the pictures directly from a camera\'s memory card, though certain frames also provide internal memory storage. Certain frames allow users to directly upload pictures to the frame\'s memory via a USB connection. However, few digital photo frames have built-in memory due to the high price of in-built memory.
Some of them also include a rechargeable battery.
Most 7 inch (17.5cm) models show images at 430 x 234 pixels. With some models the width of each landscape image is stretched to achieve an aspect ratio of 16:9, which results in very noticeable distortion.
A digital photo frame consists of three main parts, the LCD-panel, the PCB and the outside frame. The panel can have either an analog or digital interface and varies in size.
