The invention provides systems, apparatus and methods for digital image processing system providing enhanced display of elements of images generated from x-ray and other forms of attenuation data converted to grayscale digital format. Such systems, apparatus and methods capture attenuation values used to render digital images and uses the data to identify distinct gradations of the grayscale, incorporating grayscale data, e.g., within and beyond the spectrum of human vision, then recursively delineates borders based on ranges of gradation, forming irregular multi-layer visual objects with delineated internal contouring and an outer boundary, and then enhancing each delineated layer and superimposes the enhancing display over the corresponding area of the original image, thereby revealing underlying morphology of masses previously obscured, hidden or masked from human vision. The invention operates on all digital images produced by attenuation values (i.e. x-rays and sound waves); currently the invention is deployed to display organic masses in medical x-ray images, such as mammograms, to assist in diagnostic interpretation.

An image capturing apparatus includes: an image capturing circuit that outputs image capturing data by capturing an image of a photogenic field; a boundary determination circuit that determines a boundary between first and second photogenic-field regions within a first image pertaining to image capturing data output by the image capturing circuit capturing an image of the photogenic field under a first image capturing condition; an image extraction circuit that extracts a partial image corresponding to the second photogenic-field region from a second image on the basis of the boundary; and an image compositing circuit that composites the first image and the partial image.

Methods, systems, and devices implementing region of interest (ROI) histograms for display processing (e.g., for display adjustment) are described. A display processing component may determine a histogram based on the ROI (e.g., based on gray levels corresponding to pixels within a frame or image aspect ratio) by removing or otherwise not considering background filler (e.g., background, such as solid black color, that may be added by a device to fill a panel area when an image or frame aspect ratio is not equivalent to the display panel aspect ratio). Source pipe programming (e.g., display information read from a display hardware pipeline and ROI information read from a video or image pipeline) may be used for improved histogram determination or histogram modification. A histogram for processing block operations may therefore be determined based on (e.g., or modified to reflect) the ROI corresponding to the image or frame to be displayed.

A method of providing a medical image of a ROI of a patient, the method comprising: acquiring a first medical image of a region of interest (ROI) of a patient, the medical image characterized by a first signal to noise ratio (SNR); determining for a given pixel in the first image a plurality of different first image patches in the first image, each having a pixel that is coincident with the given pixel; determining for each first image patch a similar second image patch having a second SNR greater than the first SNR; determining an enhanced pixel value for the given pixel having an enhanced SNR greater than the first SNR responsive to pixel values of pixels in the determined second image patches; and using the determined pixel value to generate a second medical image of the ROI having an enhanced SNR greater than the first SNR.

Innovations in content mastering operations performed during playback of high dynamic range (HDR) video on a display device are described. When content mastering is performed during playback on a display device, a video playback system can use details retained for input HDR video (e.g., retained in metadata) and the properties of the display device to improve the perceptual quality of the HDR video as shown on that display device. For example, the video playback system can use an energy-preserving bloom operator to make bright highlights bloom into adjacent areas, thereby accentuating the bright highlights in the HDR video while operating within the constraints of the display device. The video playback system can also perform various other types of operations when content mastering is deferred until playback, including application of a lens flare operator as well as alternative tone mapping operators and alternative color gamut mapping operators selected according to metadata.

A digital graduated filter is implemented in an imaging device by combining multiple images of the subject wherein the combining may include combining different numbers of images for highlights and for shadows of the subject. The imaging device may present a user with a set of pre-defined graduated filter configurations to choose from. A user may also specify the direction of graduation and strength of graduation in a viewfinder. In an alternative implementation, combining may include scaling of pixels being added instead of varying the number of images being combined. In an alternative implementation, the combining of multiple images may include combining a different number of images for highlights of the subject than for shadows of subject.

Provided are systems, methods, and media for real-time alteration of underwater images. An example method includes receiving an image that is captured by a wearable electronic device of a user while submerged in water, in which the wearable electronic device of the user includes one or more display screens and one or more sensors, and in which the one or more sensors include one or more cameras that are configured to capture the image. The method includes adjusting the image based, at least in part, on one or more environmental factors of the water, in which the adjusting of the image includes adjusting colors of the image to compensate for changes in color while submerged in the water. The method includes causing the wearable electronic device to display the adjusted image to the user while submerged in water via the one or more display screens.

The disclosure provides a method for obtaining a fluorescent fundus image, the method including the following steps: receiving a to-be-detected color fundus image; obtaining a color feature of the to-be-detected color fundus image; encoding the color feature of the to-be-detected color fundus image according to a fundus image transformation model to transform the to-be-detected color fundus image into a to-be-detected fluorescent fundus image; and outputting the to-be-detected fluorescent fundus image.

A method for controlling brightness of an image according to the present disclosure comprises the steps of: determining a light source area on the basis of a light signal intensity of pixels included in the image; determining a surrounding area of the light source area in a predetermined manner; and compensating the brightness property of at least one of the light source area and the surrounding area on the basis of at least one of the property of the image, the property of a display device, or property of the surrounding environment.

A three-dimensional object inspecting device for inspecting a three-dimensional object includes a light source, a detector, an orientation information acquisition component, a three-dimensional shading corrector, and an inspection component. The light source emits light energy toward an inspection region set for the three-dimensional object. The detector detects radiant energy radiated from the inspection region. The orientation information acquisition component acquires orientation information about the light source and the detector with respect to the inspection region. The three-dimensional shading corrector performs three-dimensional shading correction on information corresponding to the radiant energy detected by the detector, based on shape information about the three-dimensional object in the inspection region, the orientation information, and shading correction information for a planar image detected by the detector for each of a plurality of working distances. The inspection component performs an inspection based on the information on which the three-dimensional shading correction has been performed.
