A lot of the latest products that serve the people of the public life of all technology products appear and the electronic albums also es. Electronic album is processed with related hardware and it is different with the software type of electronic albums. It generally consists of three parts: TFT LCD panel ,control chip and external frame button. Hardware electronic albums have many advantages that the traditional paper albums don’t have: high resolution, easy to save, bright colors. It breaks away from the shortings of the traditional electronic albums for example color fading as the time goes by ,hard to identify. It also can set up various switching mode to make the photographs more dynamic and to give us more beauty. Without that , the electronic albums can preserve for a longer time than the paper albums . Aavanced electronic albums can set the different background music for each photo. Because electionic albums show the photos in the LCD panel by reading the format images ,thus saving the photo is easy and overe the shortings of the traditional albums. The graduation design I will realize is the hardware electronic albums. With the so many advantages that the traditional don’t have, the electronic albums are instead of the traditional ones step by step. This paper will synthesis elaborates the graduate design in five aspects: the overview of electronic albums ,functions, hardware circuit implementation introduction,software program realization, finished thing debugging. This graduation design use the general storage devicesSD card to store the corresponding picture. In order to adapt t
