Abstract: A non-transitory machine readable medium that has a computer program for adjusting color values of an image represented in a color space. The image includes a set of pixels. Each pixel has a set of color values. The computer program receives a user input on a user interface (UI) item for adjusting color values of an image that are associated with a type of content. The computer program identifies a subset of pixels having color values that fall within a range of color values associated with the type of content. The computer program performs a color adjustment operation on the identified subset of pixels.

Abstract: Some embodiments provide a novel user interface (UI) tool that is a unified slider control, which includes multiple sliders that slide along a region. The region is a straight line in some embodiments, while it is an angular arc in other embodiments. In some embodiments, the unified slider control is used in a media editing application to allow a user to modify several different properties of the image by moving several different sliders along the region. Each slider is associated with a property of the image. A position of the slider in the region corresponds to a value of the property associated with the slider.

Abstract: Some embodiments provide a method for color balancing an image. The method receives a first selection of a first mode of a color balance tool that includes several different color balance modes. Each color balance mode is for applying color balance operations to the image. The method uses the first mode of the color balance tool to apply a first set of color balance operations to the image. The method receives a second selection to switch from the first mode to a second mode of the color balance tool. The method uses the second mode of the color balance tool to apply a second set of color balance operations to the image.

Abstract: Some embodiments provide several on-image tools of image editing application for applying effects to an image. Some on-image tools are visible to the user and are overlaid on the image. Some on-image tools are not visible. The tools are for receiving a selection of a location of the image and for applying effects to at least an area of the image that does not include the location of the image.

Abstract: A method and apparatus for generating a grayscale image. The method and apparatus receive a single value. From the single value, the method and apparatus generate a set of grayscale weighting values. The method and apparatus generate the grayscale based on a color image and the set of grayscale weighting values. By limiting the number of values to a single value, the method and apparatus prevents a user from arbitrarily selecting a number of possible weighting values which could result in a grayscale image that is too dim or too bright. This single control method and apparatus quickly and efficiently produces a grayscale image that is neither too bright nor too dim.

Abstract: A non-transitory machine readable medium that a computer program for performing a color balance operation on color values of an image represented in a color space is described. The computer program receives a selection of a location on the image that includes several pixels. Each of the several pixels of the image includes a set of color values. Based on a set of color values of a set of pixels that corresponds to the selected location of the image, the computer program identifies a set of parameters for generating a color space transform that modifies the color space. The computer program then uses the color space transform to perform a color balance operation on the image.

Abstract: In one embodiment, a method includes: obtaining a first image of a scene while an illumination component is set to an inactive state; obtaining a second image of the scene while the illumination component is set to a pre-flash state; determining one or more illumination control parameters for the illumination component for a third image of the scene that satisfy a foreground-background balance criterion based on a function of the first and second images in order to discriminate foreground data from background data within the scene; and obtaining the third image of the scene while the illumination component is set to an active state in accordance with the one or more illumination control parameters.

Abstract: Embodiments of the present disclosure can provide systems, methods, and computer-readable medium for providing virtual lighting adjustments to image data. A number of source images may be generated to individually depict solid colors of a color space (e.g., RGB color space). Virtual lighting adjustments associated with a virtual lighting mode may be applied to each source image to generate a corresponding target image. The source images and the target images may be utilized to train a model to identify pixel modifications to be applied to image data. The modifications may be associated with a virtual lighting mode. Subsequently, a user may obtain image data (e.g., an image or video) select a virtual lighting mode via an image data processing application. The previously trained model may be utilized to modify the image to apply the virtual lighting effects associated with the selected virtual lighting mode.

Abstract: Systems, methods, and computer readable media to improve the operation of electronic display systems. Techniques for inverse tone mapping operations for selected standard dynamic range (SDR) images are described. The converted images may be presented on high dynamic range (HDR) displays so as to increase a user's viewing experience (through an expanded dynamic range) while preserving the artistic content of the displayed information. Techniques disclosed herein selectively transform SDR images to HDR images by determining if the SDR images were created from HDR images (e.g., through the fusion of multiple SDR images) and if their quality is such as to permit the conversion without introducing unwanted visual artifacts. The proposed techniques apply a sigmoidal inverse tone mapping function configured to provide a perceptual-based tone mapping. Values for the function's tuning parameters may be set based on what may be determined about the original HDR-to-SDR mapping operation.
