Python PIL | ImageEnhance.Brightness() and ImageEnhance.Sharpness() method
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.Brightness() method –
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.
Syntax:
obj = ImageEnhance.Brightness(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 modulesfrom PIL import Image, ImageEnhance # Opening Imageim = Image.open(r"C:\Users\Admin\Pictures\images.png") # Creating object of Brightness classim3 = ImageEnhance.Brightness(im) # showing resultant imageim3.enhance(2.0).show() |
Output:
For first image factor is 2.0 and for second 5.0
ImageEnhance.Sharpness() method –
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.
Syntax:
obj = ImageEnhance.Sharpness(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 ImageChops modulesfrom PIL import Image, ImageEnhance # Opening Imageim = Image.open(r"C:\Users\Admin\Pictures\images.png") # Creating object of Sharpness classim3 = ImageEnhance.Sharpness(im) # showing resultant imageim3.enhance(-2.0).show() |
Output:
For first image factor is -2.0 and for second image it is 5.0
