Abstract

The invention discloses a method for realizing high definition digital photograph album based on digital optical display back projection which comprises the steps of, the digital image processing device of the high definition digital photograph album module reading the digital photos in the digital storing card and transforming them into digital signal, the digital signals of the digital photos being inputted into the digital processor through the DVI digital interface of the digital optical display projector, the digital processor of the digital optical back projector inputting the digital signals to the display driving circuit, and displaying the digital photo on the screen of the digital optical back projector.

Description

【Technical field】 [0001] The invention relates to a method for displaying a digital photo album on a video device, in particular to a method for displaying a high-definition digital photo album on a digital light display rear projection. 【Background technique】 [0002] At present, digital storage technology has been widely used in people's work and life. The digital photos stored in SecureDigital, etc.) are displayed in high-definition on the large-screen digital light display rear projection, and can be played back one by one, that is, the high-definition digital photo album function is realized. At present, the technical solution adopted to connect the digital memory card to the video equipment is: insert the digital memory card into the high-definition digital photo album (that is, the card reader), and the digital image processor of the high-definition digital photo album module reads the data in the digital memory card. After decompression, decoding, digital / analog con...
