Tempered auto-adjusting, image-editing operation

摘要

Some embodiments provide a novel method for tempering an adjustment of an image to account for prior adjustments to the image. The adjustment in some embodiments is an automatic exposure adjustment. The method performs an operation for a first adjustment on a first set of parameters (e.g., saturation, sharpness, luminance). The method compares the first set of parameters to a second set of parameters to produce a third set of parameters that expresses the difference between the first adjustment and a second adjustment. The method performs a third operation to produce an adjusted image. The first set of parameters quantify a set of prior adjustments to the image by an image capturing device when the image was captured in some embodiments. The second set of parameters is a set of target parameters. The third set of parameters specify the tempered adjustment of the image.

1. For an image editing application, a method for performing an image editing operation on an image based on a set of image processing operations performed by an image capturing device that captured the image, the method comprising:
at the image editing application, receiving an image adjusted by the set of image processing operations performed by the image capturing device, that captured the image, prior to importing the image into the image editing application; identifying a first set of parameters that quantify a first set of adjustments made to the image by the set of image processing operations performed by the image capturing device; computing a second set of parameters that quantify a desired second set of adjustments to the image based on an analysis of the image properties; deriving a third set of parameters by comparing the first and second sets of parameters; and based on the third set of parameters, performing the image editing operation on the image to produce an adjusted image.
