Python PIL | ImageEnhance.Color() and ImageEnhance.Contrast() method

  • Last Updated : 27 Jun, 2019

PIL is the Python Imaging Library which provides the python interpreter with image editing capabilities. The ImageEnhance module contains a number of classes that can be used for image enhancement.

ImageEnhance.Color() method –

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

Syntax: ImageEnhance.Color(image)

First, it is required to create an object of corresponding class in order to enhance image.




# This will import Image and ImageEnhance modules
from PIL import Image, ImageEnhance
  
# Opening Image
im = Image.open(r"C:\Users\Admin\Pictures\images.png")
  
# Creating object of Color class
im3 = ImageEnhance.Color(im)
  
# showing resultant image
im3.enhance(0.0).show()

Output:
For first image factor = 0.0 and for second image factor is 5.0.

ImageEnhance.Contrast() method –

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 grey image. A factor of 1.0 gives the original image.

Syntax:

obj = ImageEnhance.Contrast(image)
obj.enhance(factor)

First, it is required to create an object of corresponding class in order to enhance image.




# This will import Image and ImageEnhance modules
from PIL import Image, ImageEnhance
  
# Opening Image
im = Image.open(r"C:\Users\Admin\Pictures\images.png")
  
# Creating object of Contrast class
im3 = ImageEnhance.Contrast(im)
  
# showing resultant image
im3.enhance(0.0).show()

Output:
For first image factor is 5.0 and for second 0.0
