Editing media using graphical representation of media

Abstract

A non-transitory machine readable medium that has a computer program for adjusting color values of an image represented in a color space is described. The computer program displays a graphical representation of the color values of the image. The computer program receives a set of inputs on the graphical representation. In response to the received set of inputs, the computer program determines a color space transform for mapping a set of color values defined within the color space to a different set of color values. The computer program modifies the image by using the color space transform to change the color values of the image.

Description

CLAIM OF BENEFIT TO PRIOR APPLICATION[0001]This application claims benefit to U.S. Provisional Patent Application 61 / 595,650, entitled “Intuitive Media Editing,” filed Feb. 6, 2012. The U.S. Provisional Patent Application 61 / 595,650 is incorporated herein by reference.BACKGROUND[0002]Digital graphic design, image editing, and video editing applications (hereafter collectively referred to as media content editing applications or media editing applications) provide graphical designers, media artists, and other users with the necessary tools to view, analyze, and edit a variety of media content. Examples of such applications include iPhoto®, Aperture®, Final Cut Pro® and iMovie®, all sold by Apple, Inc. These applications give users the ability to analyze and edit images and videos in a variety of manners. For example, some applications provide different graphical representations of the color values of an image (e.g., histogram representation, waveform representation, vectorscope repre...

AI Technical Summary

Benefits of technology

[0020]Pixels of an image may contain luminance values that are beyond the range of black and white luminance cutoff values under different scenarios. For example, modern image-capturing devices may capture and store color values beyond the black and white luminance cutoff values in an image. Certain image file formats, such as formats that support high-dynamic range, may support color values that are outside the range of the black and white luminance cutoff values. Also, luminance values of some pixels that are originally within the range of the black and white luminance cutoff values may be pushed beyond the range by a user who is editing the image (e.g., increasing or decreasing the brightness level of at least some pixels of the image). Thus, the media-editing application of some embodiments provides a color channel histogram representation that includes a range beyond the predetermined black and white luminance cutoff values. Consequently, all pixels of the image, including pixels having luminance values darker than the black luminance cutoff value and pixels having luminance values brighter than the white luminance cutoff value, are accurately presented in the histogram.

[0021]By accurately presenting pixel data in a color channel histogram representation, a user may properly analyze and edit the image to a desired effect. For example, after learning that some of the pixels have luminance values that are brighter than the white luminance cutoff value (displayed as pure white) or darker than the black luminance cutoff value (displayed as pure black), a user may edit the image by bringing the luminance values of those pixels back within the range of black and white luminance cutoff values. In some embodiments, the user may perform such an edit by directly manipulating the color channel histogram representation of the color values of the image.

Problems solved by technology

Many media-editing applications, however, do not provide intuitive color adjustment controls.

These deficiencies cause unnecessary inconvenience in editing an image.
