摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for applying color balancing to at least a portion of a digital image based on the digital image content. The color balancing process preferably operates in a gamma modified color space, transformed into an opponent color space with separate luminance and chromatic channels. The method also includes identifying a difference of at least one of the chromatic channels between an average color, determined for a region of interest in the digital image, and an ideal reference color for the feature the user desires to correct, as a basis for the color balancing process.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for color-space selective darkness and lightness improvements. In one aspect, a method accessing multiple pixels that represent a digital image in an RGB color space. The accessed pixels are processed based on a darkness of the digital image resulting in a first set of processed pixels, and separately based on a lightness of the digital image resulting in a second set of processed pixels. Both sets of processed pixels are combined to generate a processed output image.

摘要： For an image editing application, a tool in a graphical user interface (GUI) for generating a duotone version of a subject image is provided. The tool includes several aligned thumbnail images in a slider, each thumbnail image occupying a spatial position in the slider that represents a unique range of colors. Each thumbnail image is a miniature version of the subject image that is generated based on a color within the unique range of colors represented by the spatial position of the thumbnail image. The tool determines a first color selection based on a position of a selector in the slider and a second color selection based on a complementary color of the first color selection. The tool then uses the determined color selections to generate a duotone version of the subject image.

摘要： Some embodiments provide a method of operating a device to capture an image of a high dynamic range (HDR) scene. Upon the device entering an HDR mode, the method captures and stores multiple images at a first image exposure level. Upon receiving a command to capture the HDR scene, the method captures a first image at a second image exposure level. The method selects a second image from the captured plurality of images. The method composites the first and second images to produce a composite image that captures the HDR scene. In some embodiments, the method captures multiple images at multiple different exposure levels.

摘要： Some embodiments provide a method of aligning a pair of images. The method defines multiple different pairs of images at multiple different resolutions. The method hierarchically aligns the original pair of images by first aligning the pair of images at the lowest resolution and then aligning each pair of images at each higher resolution based on the alignments of the pair of images at the lower resolutions. For some of the resolutions, to perform the hierarchically alignment, the method identifies, for at least one image at each resolution, portions that are suitable for performing the alignment and portions that are not suitable for performing the alignment. The method compares each pair of images at a particular resolution by using the suitable portions while excluding the unsuitable portions from the comparison.
摘要翻译：一些实施例提供了对准一对图像的方法。该方法以多种不同的分辨率定义了多个不同的图像对。该方法通过首先以最低分辨率对准该对图像，然后基于较低分辨率下的该对图像的对准，以每个较高分辨率对准每对图像来分级地对准原始图像对。对于一些分辨率，为了执行分层对准，该方法针对每个分辨率下的至少一个图像识别适合于执行对准的部分和不适于执行对准的部分。该方法通过使用合适的部分以特定分辨率比较每对图像，同时排除比较中的不合适部分。

摘要： This disclosure pertains to devices, methods, systems, and computer readable media for generating and/or interpreting image metadata to determine input parameters for various image processing routines, e.g., filters that distort or enhance an image, in a way that provides an intuitive experience for both the user and the software developer. Such techniques may attach the metadata to image frames and then send the image frames down an image processing pipeline to one or more image processing routines. Image metadata may include face location information, and the image processing routine may include an image filter that processes the image metadata in order to keep the central focus (or foci) of the image filter substantially coincident with one or more of the faces represented in the face location information. The generated and/or interpreted metadata may also be saved to a metadata track for later application to unfiltered image data.
摘要翻译：本公开涉及用于生成和/或解释图像元数据以确定各种图像处理例程的输入参数的设备，方法，系统和计算机可读介质，例如以提供直观体验的方式来扭曲或增强图像的滤波器用于用户和软件开发人员。这样的技术可以将元数据附加到图像帧，然后将图像帧沿图像处理流水线发送到一个或多个图像处理例程。图像元数据可以包括面部位置信息，并且图像处理例程可以包括处理图像元数据的图像滤波器，以便保持图像滤波器的中心焦点（或焦点）基本上与一个或多个在面部位置信息。所生成的和/或解释的元数据也可以被保存到元数据轨道，以备将来应用到未过滤的图像数据。
