    摘要: A computer with a monitor viewable program executes to display a histogram of image data on the monitor. The monitor contemporaneously displays a screen image viewed on a monitor of the histogram, and displays a digital or analog control element that controls both compression and expansion of midtones. Activation of the midtone compression/expansion element alters the displayed image according to effects of programs underlying the control of the element. This histogram display and element are associated on a single logical screen display in which at least one other image data modification effect is present on the screen image as an addressable image data modification effect.

    摘要: A color correction device for correcting colors in a color image comprises: coordinates for registering points in a first color space of at least one standard point, the first color space having axes for specifying colors; a second set of coordinates for registering points in a second color space of at least one standard point, the second color space having coordinates that include at least one coordinate for specifying color hue; a translator to convert image data of at least one point in the first color space to coordinates in the second color space; a modifier for modifying at least hue within image data in the second color space to form corrected image data in the second color space; and a translator for transferring corrected image data in the second color space to corrected image data in the first color space. The color correction device may include a means for creating a tone reproduction curve based on conceptually moving one or other limit of a range of image color values in order to provide a tone reproduction curve with improved rendering of the color correction.

    摘要: A method of removing an object from a digital image comprising, displaying a digital image derived from digital image data, overlaying a virtual frame to surround a sub-region of the digital image that contains at least a part of the object and a portion of the digital image that does not comprise the object, identifying the defect or object to be removed by apportioning the virtual frame into object and non-object regions, modifying the digital data to amend data relating to object regions so that the data more closely resembles data of non-object regions, the step of modifying the digital data including combining noise into the digital data of the object.

    摘要: After identification of an image or image area where correction is to be effected for red-eye defects, and identification of eye regions within the image or the image area, color data from the area is provided, collected or analyzed according to color channel information. The color channel information may be defined for specific or collections of wavelength values or color content values, usually with at least two channels, up to four or more color channels used to carry all of the information (and with digital images, pixel information) for each color. By using color channel information, local color content information can be readily accessed and evaluated, and after the exact nature or degree of a red-eye effect is determined from evaluation of the color channel information, the data may be readily corrected by a number of different techniques. Templates of colors and/or templates for features (such as glint, pigmentation, or artistic features) may be added to identified regions to be corrected for red-eye

    摘要: A method of correcting image saturation is performed by defining saturated colors in a chromaticity color space; and deriving an overall correction of the saturation of colors in the image using the defined saturation of these colors in conjunction with a table of corrections indexed by hue and lightness. This process has a unique attribute of being able to automatically decrease saturation in regions of an image where oversaturation is detected. I'd like not to specify the actual form of the correction until well down in the claims. We have things that work but they could probably be improved, so there's no point in tying oneself to these specifics. My references to preferred incarnations of various things should signpost that for you.

    摘要: A method corrects a color image by averaging at least two color channels in regions near the minimum of histograms of the at least two color channels; selecting the smallest of the average color values as a black point; averaging at least two color channels in regions near the maximum of the histograms of the at least two color channels and selecting the largest of the average color values as a white point; and correcting the at least two color channels by adjusting the smallest and the largest color averages to the respectively match the values of the black point and white point to form corrected image data. A preferred method limits the adjustment to a predetermined amount of clipping of the at least two color channels.
