摘要

数码相框是可以直接展示数码照片不用将照片冲印出来再展示

的新型相框。它采用传统普通相框的外框(外观)造型，把传统普通相

框的中 间照片部分换成液晶显示屏，配上，存储介质等部件，可以直

接展示(播放)数码照片，同时，可以在同一个相框内循环展示(播放)

不同照片，给 日益增多的数码照片和喜好照片的人们提供一个更好的

照片展示平台和空 间。 数码相框的外观造型与传统普通相框一样(当

然在尺寸和款式方面也与传统普通相框一样可以多样选择)，不过数

码相框不像传统普通相框那样需要将数码照片冲印出来再装到相框

里展示，而是通过直接插上相机的存储卡或者直接将数码相片拷到数

码相框的就可以马上在相框里展示出来，而且它可以存储和展示(播

放)几百张甚至上千张的照片。

本文介绍了一种基于 Linux 嵌入式系统的新型网络数码相框设计方

案。本设计方案采用 ARM 为核心的嵌入式系统，构建了基于 Linux 的网

络多媒体共享文件系统，详细论述了此 Web 数码相框系统的软、硬件设

计，该设计方案具有一定的 用性。

Digital photo frame is digital photos can be directly display photos

will not print it show the new frame again. It adopts the traditional

common frame of frame (appearance) modelling, traditional frame of the

middle of the ordinary photos with LCD display, part with power,

storage medium components that can be directly display (play) digital

pictures, at the same time, can be in same circulation within the frame

display (play) different photos, to growing digital photos and pictures of

be fond of people to provide a better photos show platform and space.

The appearances of the digital photo frame with traditional common

picture frames as well (of course in size and design respect also and the

traditional ordinary frame can be varied as choice), but the digital photo

frame as traditional ordinary frame that need a digital photo print it put

to the photo frame display, but rather through directly on the camera's

memory card or directly will digital photos to the digital photo frame of

memory kao you can instantly in the photo frame displayed, and it can

store and display (play) hundreds of thousands of pictures of zhang even.

This paper introduces a kind of embedded system based on Linux

the new network digital photo frame design scheme. This design scheme

adopts ARM as the core of the embed
