    Abstract: Devices, methods, and program storage devices for creating and/or displaying backwards-compatible High Dynamic Range (HDR) images are disclosed, comprising: obtaining two or more exposures of a scene; creating a gain map based on at least one of the two or more exposures, wherein the gain map comprises a plurality of pixels each corresponding to a portion of the scene, and wherein values of the pixels in the gain map comprise indications of a brightness level of the corresponding portions of the scene; combining the two or more exposures to form a first image; tone mapping the first image based on a Standard Dynamic Range (SDR) format to generate a first SDR image of the scene; and storing the first SDR image and created gain map in a first enhanced image file. The first enhanced image file may be, e.g., a HEIF, HEIC, PNG, GIF, JPEG, or other suitable file format.

    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: Adaptive bracketing techniques for photography are described. An adaptive bracketing logic/module directs an imaging device to capture an adaptive bracket. The adaptive bracket can include a first image captured at a first exposure value, a second image captured at a second exposure value, and a third image captured at the first exposure value. The first exposure value can be underexposed in comparison to the second exposure value. The adaptive bracketing logic/module can determine that a difference between the first and second images; determine that the third image is more similar to the second image than the first image; and generate a composite image using the first image and the third image. The adaptive bracketing logic/module can also update the adaptive bracket to include the composite image. Optionally, the updated adaptive bracket can be used to generate one or more high dynamic range (HDR) images. Other embodiments are described.

    Abstract: A method and system for providing a dynamic grain effect tool for a media-editing application that generates a grain effect and applies the grain effect to a digital image. The application first generates a random pixel field for the image based on a seed value. The application then generates a film grain pattern for the image by consecutively applying a blurring function and an unsharp masking function, based on an ISO value, to the randomly generated pixel field. The application then blends the grain field with the original image by adjusting each pixel based on the value of the corresponding pixel location in the grain field. The application then adjusts the grain amount in the previously generated full-grain image by receiving a grain amount value from a user and applying this value to the full-grain image.

    Abstract: 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.

    Abstract: A method and system for controlling multiple image editing controls using one master control. The system identifies various characteristics of an image being edited. The system generates, for each of multiple image editing controls, a relationship between the master control and the image editing control. The relationship is based on at least one of the identified characteristics of the image being edited. The relationship is different for different images when the different images have different characteristics, such as different average color component values at a particular percentile of pixels in the images.

    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 that provides a graphical user interface (GUI) for color balancing an image. The method provides a display area for displaying the image. The method provides several color balance modes. The method provides a user interface (UI) control associated with a color balance mode in the several color balance modes. The UI control performs a color balance operation on the image by (1) identifying a color cast in the image and (2) modifying pixels in the image based on the pixels' luminance values in order to reduce the color cast in the image.
