TECHNIQUES FOR PRESENTING USER ADJUSTMENTS TO A DIGITAL IMAGE

摘要

Techniques for generating a preview image in an image editing application in response to detecting user input that changes the value of an adjustable parameter of a digital image undergoing adjustment. According to one technique, instead of processing the digital image through a filter chain to generate an updated preview image, a blended image is generated through interpolation of two previously generated versions of the digital image. The previously generated versions may be generated through the filter chain. The blended image may be generated in a shorter amount of time in response to the user's adjustment than the time needed to process the digital image through the filter chain. Thus, the current preview image may be updated with the blended image sooner than is possible if the current preview image is updated by processing the digital image through the filter chain.

主权项

1. A computer-implemented method, comprising:
generating a first version of a digital image and a second version of the digital image; wherein the first version of the digital image reflects a first plurality of values of a corresponding plurality of image adjustment parameters; wherein the second version of the digital image reflects a second plurality of values of the corresponding plurality of image adjustment parameters; wherein the first plurality of values are the same as the second plurality of values except for values that correspond to one particular image adjustment parameter of the plurality of image adjustment parameters; wherein the value, in the first plurality of values, for the particular image adjustment parameter is a first particular value; wherein the value, in the second plurality of values, for the particular image adjustment parameter is a second particular value; wherein the first particular value is different from the second particular value; and detecting that a user interface control associated with the particular image adjustment parameter is changed to a particular setting that corresponds to a third particular value that is between the first particular value and the second particular value; and in response to detecting that the control is changed to the particular setting, blending the first version of the digital image and the second version of the digital image to generate and display a blended version of the digital image.
