Abstract
A method of adjusting the color characteristics of a digital image includes receiving a digital image including a plurality of pixels, receiving non-pixel data relating to camera capture parameters including an aperture value, an exposure time value, and a speed value specific to the received digital image; using the aperture value, time value, and speed value to calculate a scene brightness value; and using the calculated scene brightness value to adjust the color of the digital image.
Claims18
A method of adjusting the color characteristics of a digital image comprising:
- (a) receiving a digital image including a plurality of pixels,
- (b) receiving non-pixel data relating to camera capture parameters including an aperture value, an exposure time value, and a speed value specific to the received digital image;
- (c) using the aperture value, time value, and speed value to calculate a scene brightness value;
- and
- (d) using the calculated scene brightness value to adjust the color of the digital image.
A method of adjusting the color characteristics of a plurality of digital image comprising:
- (a) receiving a first and a second digital image, each digital image including a plurality of pixels,
- (b) receiving non-pixel data relating to camera acquisition parameters for the first digital image an aperture value, an exposure time value, and a response speed value;
- (c) receiving a measured scene brightness value for the second digital image from which the digital image is derived;
- (d) using the aperture value, exposure time value, and speed value to calculate a scene brightness value for the first digital image;
- (e) using the calculated scene brightness value to adjust the color of the first digital image;
- and
- (f) using the measured scene brightness value to adjust the color of the second digital image.
