ImageEnhance Module#

The ImageEnhance module contains a number of classes that can be used for image enhancement.

Example: Vary the sharpness of an image#

from PIL import ImageEnhance

enhancer = ImageEnhance.Sharpness(image)

for i in range(8):
    factor = i / 4.0
    enhancer.enhance(factor).show(f"Sharpness {factor:f}")

Also see the enhancer.py demo program in the Scripts/ directory.

Classes#

All enhancement classes implement a common interface, containing a single method:

class PIL.ImageEnhance._Enhance[source]#
enhance(factor)[source]#

Returns an enhanced image.

Parameters:

factor – A floating point value controlling the enhancement. Factor 1.0 always returns a copy of the original image, lower factors mean less color (brightness, contrast, etc), and higher values more. There are no restrictions on this value.

class PIL.ImageEnhance.Color(image)[source]#

Adjust image color balance.

This class can be used to adjust the colour balance of an image, in a manner similar to the controls on a colour TV set. An enhancement factor of 0.0 gives a black and white image. A factor of 1.0 gives the original image.

class PIL.ImageEnhance.Contrast(image)[source]#

Adjust image contrast.

This class can be used to control the contrast of an image, similar to the contrast control on a TV set. An enhancement factor of 0.0 gives a solid gray image, a factor of 1.0 gives the original image, and greater values increase the contrast of the image.

class PIL.ImageEnhance.Brightness(image)[source]#

Adjust image brightness.

This class can be used to control the brightness of an image. An enhancement factor of 0.0 gives a black image, a factor of 1.0 gives the original image, and greater values increase the brightness of the image.

class PIL.ImageEnhance.Sharpness(image)[source]#

Adjust image sharpness.

This class can be used to adjust the sharpness of an image. An enhancement factor of 0.0 gives a blurred image, a factor of 1.0 gives the original image, and a factor of 2.0 gives a sharpened image.
