Image Bit Depth or Color Depth of an Image.
The number of bits required to store each pixel’s color information. It depends on the image formats and the numbers of colors the images have. It ultimately shows the number of unique colors available in the image. Higher the bit depths have the high image quality i.e. higher the bit depth or color depth the number unique color is high.
For example.
If the Color depth of an image is 8 means it has 256 unique colors.
Color depth = 8;
Number of unique colors = 2^8 = 256
Depends on the number of colors bit depth can be classified as the following
- 1 bit images
- 2 bit images
- 3 bit images
- 4 bit images
- 5 bit images
- 6 bit images
- 7 bit images
- 8 bit images
- 24 bit images
- 32 images
- 48 images
