SELECTIVE BRIGHTNESS CONTROL IN PHOTOGRAPHY

摘要

A computer determines one or more brightness levels associated with a first set of pixels within a light source in an image. The computer determines a brightness effect on a second set of pixels in the image based on the one or more brightness levels associated with the first set of pixels within the light source. The computer receives input to alter at least one of the one or more brightness levels associated with the first set of pixels within the light source. The computer alters one or more brightness levels associated with the second set of pixels in the image based on the received input and the determined brightness effect.

主权项

1. A computer system for altering the brightness level of a pixel, the computer system comprising:
one or more computer processors, one or more computer-readable storage media, and program instructions stored on the one or more of the computer-readable storage media for execution by at least one of the one or more processors, the program instructions comprising: program instructions to determine that an image is about to be captured by detecting that photographic software is operating and focused on the image for greater than a threshold time; program instructions to receive a first user input detailing a light source in the image; program instructions to determine one or more brightness levels associated with a first set of pixels within the light source; program instructions to determine a brightness effect on a second set of pixels in the image based on the program instructions to determine one or more brightness levels associated with the first set of pixels; program instructions to determine one or more brightness levels associated with a second set of pixels in the image; program instructions to receive a second user input to alter at least one of the one or more brightness levels associated with the first set of pixels; program instructions to determine a second brightness effect on the second set of pixels based on the one or more altered brightness levels associated with the first set of pixels; and program instructions to alter the one or more brightness levels associated with the second set of pixels in the image based on program instructions to subtract the determined second brightness effect on the second set of pixels from the determined one or more brightness levels associated with the second set of pixels.
