ImageAdjust[image]
adjusts the levels in image, rescaling them to cover the range 
to 
.
ImageAdjust[image, c]
adjusts the contrast of image by an amount c.
ImageAdjust[image, {c, b}]
adjusts the contrast by an amount c and the brightness by an amount b.
ImageAdjust[image, {c, b, 
}]
also performs a gamma correction by raising values to the power .
ImageAdjust[image, corr, {inmin, inmax}]
first rescales so that the range of input values 
to 
is mapped to 
to 
.
ImageAdjust[image, corr, {inmin, inmax}, {outmin, outmax}]
rescales so that the range of input values 
to 
is mapped to 
to 
.
Details
- ImageAdjust works with images involving any number of channels.
- Zero adjustment corresponds to contrast adjustment
, brightness adjustment 
, and gamma correction 
. - When rescaled values lie outside the range
to 
, they are clipped. - All correction and range parameters can be given as lists to specify different treatment for different channels in the image.
- Range parameters can be set to Automatic to indicate the minimum or maximum of the values that occur in the image.
- When applied to color images, ImageAdjust always returns an RGB image.
