Abstract: A method for adjusting color saturation can determine a saturation adjustment from metadata that specifies an adjustment of color saturation based on a first display and from precomputed data, such as data in one or more look-up tables, that specifies a relationship between image data in a first color space and image data in a second color space. An input image in the first color space is converted into an image in the second color space, and the color saturation is adjusted while the image data is in the second color space, which can be a geometrically non-symmetrical color space.

Abstract: Color trim data is used in an approximation function to approximate one or more non-linear transformations of image data in an image processing pipeline. The color trim data is derived in one embodiment through a back projection on a colorist system, and the color trim data is used at the time of rendering an image on a display management system.

Abstract: Methods and systems for controlling judder are disclosed. Judder can be introduced locally within a picture, to restore a judder feeling which is normally expected in films. Capture time and display time of frames can be manipulated to obtain a desired amount of judder. Frames can be interpolated to obtain a film with a higher frame rate and localized control of judder.

Abstract: Systems and methods are disclosed for dynamically adjusting the backlight of a display during video playback or for generating filtered video metadata. Given an input video stream and associated metadata values of minimum, average, or maximum luminance values of the video frames in the video stream, values of a function of the frame min, mid, or max luminance values are filtered using a temporal filter to generate a filtered output value for each frame. At least one filtering coefficient of the temporal filter is adapted based on a logistic function controlled by slope and sensitivity values. The instantaneous dynamic range of a target display is determined based on the filtered metadata values and the minimum and maximum brightness values of the display.

Abstract: A substantially rectangular spectral representation is synthesized, which is adapted to produce image capture device sensor outputs if applied to an image capture device. The synthesized substantially rectangular spectral representation can be utilized in generating output color values of an output color space from image capture device sensor outputs, where the image capture device sensor outputs correspond to an image captured by an image capture device. The generated output color values correspond to colors perceived by the human visual system for the same image as that captured by the image capture device. Image capture device gamut is also determined.

Abstract: A method and system for retouching digital images for a motion picture removes semi-transparent artifacts or ‘blotches’ caused by contaminates in the optical path of the camera. This approach provides the benefit of only having to retouch a single average image that is than automatically applied via a correction power map to the entire sequence of images for the affected scene. The formation of an average image tends to reinforce the artifacts making them easier to identify and reduce background detail making it easier to retouch the artifact.

Abstract: An efficient and robust mechanism for static pattern removal from movies captured with a digital CCD camera. A correction map of malfunctioning underexposed CCD pixels is provided and applied to each image in the affected shot to correct the malfunctioning pixels. The correction map may be associated with the specific images in a given shot or with a particular CCD camera. The entire process, other than possibly the initial step of determining which shots to correct, is fully-automated on a computer workstation. The computer generates the correction map, applies it to each image and validates the correction. This is a considerably more efficient approach than one in which a technician must determine there is a problem of under exposure, identify the malfunctioning pixels in each frame and manually retouch the affected pixels.
