Method for dynamic range editing

摘要

A method of displaying a high dynamic range image, comprising receiving the high dynamic range image, calculating a first set of tone mapping parameters as a function of the high dynamic range image, sub-sampling the first set of tone mapping parameters at a first resolution to create a first sub-sampled parameter set, creating a first tone-mapped image by processing the high dynamic range image as a function of the first sub-sampled parameter set, and displaying the first tone-mapped image. A method of composting a plurality of versions of an image to create the high dynamic range image is also disclosed such that the compositing may be modified as a function of received user input.

1. A computer-implemented method to generate a high dynamic range image, the method comprising:
receiving a plurality of images, each of the plurality of images having an image detail represented by a value with a characteristic having a value that represents the characteristic for the respective one of the plurality of images, wherein at least two of the images have a different value for the image detail characteristic; determining a parameter, wherein the parameter is determined based on the values of the characteristic image detail for the plurality of images; determining a response function based on the plurality of images; after determining the response function, generating a plurality of edited images by altering the value of the characteristic image detail for each of the plurality of images based on the parameter; and merging the plurality of edited images to construct a high dynamic range output image; and tone mapping the high dynamic range output image based, at least in part on the response function.
