  • Patent number: 10834329
    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.

  • Publication number: 20190370942
    Abstract: Systems and methods are disclosed for correcting red-eye artifacts in a target image of a subject. Images, captured by a camera, including a raw image, are used to generate the target image. An eye region of the target image is modulated to correct for the red-eye artifacts, wherein correction is carried out based on information extracted from at least one of the raw image and the target image. Modulation comprises detecting landmarks associated with the eye region; estimating spectral response of the red eye artifacts; segmenting an image region of the eye based on the estimated spectral response of the red eye artifacts and the detected landmarks, forming a repair mask; and modifying an image region associated with the repair mask.

  • Patent number: 9652867
    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.

  • Patent number: 9247133
    Abstract: This disclosure pertains to devices, methods, and computer readable media for performing image registration. A few generalized steps may be used to carry out the image registration techniques described herein: 1) acquiring image data from an image sensor; 2) selecting a pair of overlapping image portions from the acquired image data for registration; 3) determining an area of “maximum energy” in one of the image portions being registered; 4) placing an image registration window over both image portions at the determined location of maximum energy; 5) registering the overlapping image portions using only the image data falling within the image registration windows; and 6) determining, according to one or more metrics, whether the image registration window should be shifted from a current location before registering subsequently acquired image portions.

  • Patent number: 9053568
    Abstract: Techniques are disclosed to provide user control over the manipulation of a digital image. The disclosed techniques enable a user to apply various textures that mimic traditional artistic media to a selected image. User selection of a texture level results in the blending of texturized versions of the selected image in accordance with the selected texture level. User selection of a color level results in the adjustment of color properties of the selected image that are included in the output image. Control of the image selection, texture type selection, texture level selection, and color level selection may be provided through an intuitive graphical user interface.

  • Patent number: 8971623
    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.
