Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
49 words
A method for modifying the spatial frequency detail of a
digital image channel, the method comprising: (a) receiving a digital image channel; (b) providing a tone scale function; and, (c) modifying the spatial frequency detail of the digital image
channel based on the characteristics of the tone scale function.
Claim 2
Dependent Claim
26 words
The method as in claim 1, wherein step (a) includes
receiving the digital image channel having the tone scale function applied to the
digital image channel.
Claim 3
Dependent Claim
19 words
The method as in claim 1 further comprising the step of
applying the tone scale function after step (c).
Claim 4
Dependent Claim
24 words
The method as in claim 3 further comprising the step of
applying a tone scale function approximating the characteristic tonal response of a
device.
Claim 5
Dependent Claim
20 words
The method as in claim 1, wherein step (c) includes using a
control signal to modify the spatial frequency detail.
Claim 6
Dependent Claim
20 words
The method as in claim 2, wherein step (c) includes using a
control signal to modify the spatial frequency detail.
Claim 7
Dependent Claim
18 words
The method as in claim 6 further comprising extracting the
spatial frequency detail from the digital image channel.
Claim 8
Dependent Claim
29 words
The method as in claim 1, wherein the step of modifying of
the spatial frequency detail is proportional to the inverse of the slope of the tone
scale function.
Claim 9
Dependent Claim
27 words
The method as in claim 2 wherein the modification of the
spatial frequency detail is proportional to the inverse of the slope of the tone scale
function.
Claim 10
Dependent Claim
27 words
The method as in claim 3 wherein the modification of the
spatial frequency detail is proportional to the inverse of the slope of the tone scale
function.
