Most modern digital cameras use 24 bits (8 bits per primary) to represent a color. But more or less can be used, depending on the quality desired.
Many early computer graphics cards used only 4 bits to represent a color.
A "black and white" image is generally actually a grayscale image, which is typically represented with 8 bits per pixel. However, you can make images that use only one bit per pixel, making each pixel either fully black or fully white. The images created by the early graphics software MacPaint used only one bit per pixel.
There are 2 colors in bits per pixel - 4 colors in 2 bits per pixel - 16 colors in 4 bits per pixel and similarly this sequence continuous going on.
To represent 256 colors it is needed 8 bit per pixel. 1 bit mean 2 colors, 2 bits mean 4 colors, 3 bits per pixel can represent 8 colors... 8 bits = 256 colors.

as a simple example assume you want divide a gray level secret image to two shares. Each pixel in the secret image is expanded to four subpixels in each share that consist of white and black so width and height of shares is twice of secret image. first share is an image wich has random pixels of black or white with equal probability. in second share, if corresponding pixel in main secret image is white then the pixel in second share is the same as first share and if pixel in the secret image is black, corresponding pixel in second share would be inverse of the same pixel in first share.
Many pixels make up one image. A pixel is like one tiny piece of an image.

Image processing involves various operations on images. An image is a collection of pixels. Each pixel has its position and resolution.
a pixel is the smallest element in an electronic image
Bitmap image is raster or pixel based image. Bitmap image is made up of pixels, every pixel in grid have its own position and color. Pixels are mapped to the pixel grid, that's why its name is Bitmap.
its store 1bit per pixel
Pixel
A pixel is one dot in the image. A 10 megapixel camera will have 10 million pixels that make up the image.
Types of images are: 1.Compressed image 2.RGB image (True Color Image & has 3 pixels ) 3.RGBA image (True Color Image & has 4 pixel or more ) 4.Grayscale image (Black & White) 5.Palette image (16 colors per pixel ) All i want is to " Like" ! Thanks !
Pixel Pitch is the measurement of the smallest bit of data in a video image. The smaller the size of the pixels in an image, the greater the resolution.
