    • A system and related techniques provide a uniform abstraction layer for accessing and manipulating Raw image files, with the necessity for proprietary application tools. According to embodiments in one regard, an operating system or other platform may expose a set of application programming interfaces (APIs) to general purpose image processing, photo album, printing or other applications through which a Raw API layer may be accessed. That layer may in turn communicate via a set of Raw codecs or other protocols or channels with a hardware-specific Raw plugin layer, which may host a set of Raw format specifications supplied, for instance, by digital still camera manufacturers or other vendors. Those hardware-specific, low-level specifications may specify or encapsulate, for example, the Raw container or file format, Raw file metadata, thumbnail representations or other details for individual Raw formats. Because the necessary Raw translation is abstracted to the operating system or other platform, diverse applications may seamlessly use Raw image files from a variety of camera and other manufacturers, without a need for proprietary tools. Users may therefore gain access to the highest possible resolution representation of image data captured by a given imaging device, transparently and without a need to switch tools between different manufacturers' cameras or devices.
    • 系统和相关技术为访问和操纵原始图像文件提供了统一的抽象层,具有专有应用工具的必要性。 根据一个方面的实施例,操作系统或其他平台可以将一组应用程序编程接口(API)暴露给通用图像处理,相册,打印或可以访问Raw API层的其他应用程序。 该层还可以经由一组原始编解码器或其他协议或信道与硬件特定的原始插件层进行通信,其可以承载例如由数码相机制造商或其他供应商提供的一组原始格式规范。 这些硬件特定的低级规范可以指定或封装例如Raw容器或文件格式,Raw文件元数据,缩略图表示或各种Raw格式的其他细节。 由于必要的原始翻译被抽象到操作系统或其他平台,不同的应用程序可以无缝地使用来自各种相机和其他制造商的Raw图像文件,而无需专有工具。 因此,用户可以透明地访问由给定成像设备捕获的图像数据的最高可能分辨率表示,并且不需要在不同制造商的相机或设备之间切换工具。
