【摘要】：在3D时代即将到来的今天，3D数码相机，3D图片和视频已经开始融入了普通家庭。越来越多的3D图片及视频需要展示的媒介。在3D电视上显示图片，由于受固定地点和需要佩戴特定眼睛的约束，缺乏灵活性。而传统的数码相框体积小巧，移动方便，却仅仅支持2D图片和视频。因此研发出既能播放2D图片和视频，又能播放3D图片和视频的数码相框，对推动3D行业的发展和数码相框的普及具有深远的影响。要研发3D数码相框产品，首要解决的问题就是要选择合适的裸眼3D技术。目前裸眼式3D技术可分为光屏障式、柱状透镜技术和指向光源三种。由于光屏障式裸眼3D技术与既有的LCD液晶工艺兼容，在量产性和成本上较具优势。因此，大部分的裸眼3D数码产品都是基于光屏障式。结合到数码相框产品的实际情况，产品集成方案比较独立，数码相框主芯片只支持图片解码，视频解码等，对3D液晶屏技术整合及支持较少。因此，可以充分的利用这个行业的薄弱环节进行自主创新和产品集成。为了使产品更符合消费者的使用习惯，本产品硬件选用嵌入式微处理器芯片AML6236作为主控芯片，在已有2D数码相框的基础上增加了”T2硬件交织芯片”和更换了LCD液晶屏为光屏障式裸眼3D液晶屏；在软件设计方面，在2D数码相框的基础上，设计了新的图片显示比例模式，能调节3D图片的显示比例，同时兼容2D图片的显示比例调节；能通过手动调节让3D图片的出屏率，使立体效果达到最佳；实现了3D图片的放大缩小功能；支持外挂，内置等多种3D字幕格式；自定义了图片和视频文件自动识别条件，以及支持对全幅/半幅格式的3D视频文件的自动识别。所设计的裸眼3D技术在数码相框，通过了产品功能与性能设计，，其应用与设计方法为同类的技术的应用与产品设计提供了参考。
[Abstract]:In the coming days of the 3D age, 3D digital cameras and video have begun to blend into ordinary families. More and more 3D images and videos need to be displayed in media. Displaying images on 3D TV is inflexible due to fixed location and the need to wear specific eyes. Traditional digital photo frames are compact and easy to move, but only support 2D images and videos. Therefore, the development of digital photo frames, which can play 2D pictures and videos as well as 3D images and videos, has a profound impact on the development of 3D industry and the popularity of digital photo frames. In order to develop 3D digital photo frame, the most important problem is to choose suitable naked-eye 3D technology. At present, the naked-eye 3D technology can be divided into three types: light barrier, cylindrical lens and pointing light source. Due to the compatibility of optical barrier 3D technology with existing LCD liquid crystal process, it has advantages in mass production and cost. As a result, most naked-eye 3D digital products are based on light barriers. Combined with the actual situation of the digital photo frame product, the product integration scheme is relatively independent, the main chip of digital picture frame only supports picture decoding, video decoding and so on, and less integration and support for 3D LCD screen technology. Therefore, we can make full use of the weak links of this industry for independent innovation and product integration. In order to make the product more in line with the consumer's usage habits, the hardware of this product adopts the embedded microprocessor chip AML6236 as the main control chip. On the basis of 2D digital photo frame, we add "T2 hardware interleaving chip" and replace LCD liquid crystal screen as light-barrier 3D liquid crystal screen. In software design, we design a new picture display scale mode based on 2D digital photo frame. Can adjust the display ratio of 3D image, and can adjust the display proportion of 2D image; can adjust the display rate of 3D image manually to achieve the best stereoscopic effect; realize the function of enlarging and shrinking 3D image; support external storage, Automatic recognition conditions for images and video files are defined, and automatic recognition of 3D video files in full / half format is supported. The naked eye 3D technology is designed in the digital frame, and the function and performance of the product are designed. The application and design method provide reference for the application and product design of the same kind of technology.
