Multiple uncompressed digital images, each at a different exposure, may be captured automatically in response to an image capture request. The set of uncompressed digital images may be stored as a single data object and manipulated to produce a final digital image.

Digital image production method and apparatus

An electronic image capture device including an image capture array, an optional image stabilization gyro, a processor, and a display is configured to detect the amount shaking of the device either prior to, or during image capture. When the shaking of the device exceeds a threshold required for the capture of quality images, the user of the image capture device is notified through the display that excessive shake has been detected and may be advised on methods to reduce or eliminate the shake.

A method is provided for correcting a captured image. The method comprises determining an illuminant for the captured image. When the determined illuminant matches a reference illuminant the image is corrected with a reference inversion mask. When the determined illuminant matches a first extreme illuminant, the reference inversion mask is modified using a first set of reference point ratios that corresponds to the first extreme illuminant and the image is corrected with the modified inversion mask. When the determined illuminant does not match the first extreme illuminant, a set of reference point ratios are calculated for the determined illuminant. The reference inversion mask is modified using the calculated set of reference point ratios and the image is corrected with the modified inversion mask.

Reducing or eliminated color-dependent vignetting in a digital camera includes: providing, for each color that said camera can image, a raw array of data corresponding to a desired scene; and changing the raw arrays such that the array for each color exhibits substantially the same amount of vignetting so as to reduce color-dependent vignetting in a composite image based upon each of the changed arrays.

A digital camera and method that embodies a preview image that shows what the final image will look like, including depth of field and shutter speed temporal effects (blur). Preview images are displayed as a series of stop-action still images rather than as continuous video. Overlays or picture-in picture can be used to show live action video simultaneously for framing.

Disclosed are systems and methods for providing spatially-varied demosaicing. In one embodiment, a system and method pertain to collecting color information sensed by image sensor pixels, and estimating color information as to a pixel under consideration that is not collected by the pixel by weighting color information collected by adjacent pixels that are positioned in a direction in which color is shifted due to lateral chromatic aberration.

Systems and methods for providing spatially-varied demosaicing

A method of local contrast mapping that changes the dynamic range of an original image to more closely match the dynamic range of the medium used for the reproduction. The method compresses large contrast differences between different areas of an image while preserving small contrast differences between different areas of an image.

Method for improved contrast mapping of digital images

An image cropping system utilizes memory, an object detector, and an image cropper. A set of digital data that defines a graphical image is stored in the memory. The object detector analyzes the set of digital data and automatically identifies a portion of the digital data that defines an image of a particular object. The image cropper then uses the identified portion to determine a position of the object image within the graphical image. Based on the position of the object image within the graphical image, the image cropper automatically crops the digital data. In this regard, the position of the object image within the graphical image serves as a reference for determining which portions of the set of digital data should be cropped.

System and method for automatically cropping graphical images

A graphical system enables users to edit graphical images. The graphical system utilizes memory for storing graphical data and an image manager. The image manager is configured to render a first set of the graphical data based on a first setting of an editing parameter. The first graphical data set defines a first image. The image manager is also configured to render a second set of the graphical data based on a second setting of the editing parameter in response to a user input and to render a third set of the graphical data based on a third setting of the editing parameter in response to the user input. The second setting is different than the third setting thereby enabling a user to comprehend, by visually comparing an image defined by the second graphical data set to an image defined by the third graphical data set, an effect of updating the editing parameter for the first image.

The present disclosure relates to systems and methods for customizing a software application interface. A method for modifying a software application contains the following steps: identifying the operator; acquiring an operator profile; setting a threshold value; monitoring the operator's use of the software; and modifying a functional interface when the threshold is exceeded.

System and method for developing custom operator-specific software-applications

A digital imaging system includes a color appearance handling capability that utilizes a database including actual image data and information relating to the actual image data to control illumination and color in digital images. The digital imaging system controls illumination and color with a color-by-correlation technology that includes an illuminant detection training algorithm that bases control of illumination and color on a database storing actual illuminants, scenes, and subjects from representative image acquisition devices such as digital cameras and scanners. In one example, illuminant detection training is accurately rendered for a variety of illuminants, scenes, and subjects that are expected to be of interest to users of a particular camera or group of cameras. In the example, the database is formed by user-group submissions from users of a particular camera or group of cameras. The digital imaging system accesses a database capable of supplying actual image data including illuminants, chromaticities, colors, and the like. The database also stores information relating to the actual image data including tags that identify the image acquisition device that acquires a particular image, and information relating to manufacturer, model and version of the image acquisition device, and image acquisition devices settings at the time of acquisition.
