Question

A color image uses 16bits to represent a pixel. What is the maximum number of different colors that can be represented?

Answer 1

Answer:

With 16 bits , we can represent up to 216 different colours

Answer 2

Pixel:

Explanation:

• In digital imaging, a pixel is the least addressable element in a raster image or the smallest addressable element in an all points addressable display device.
• So it is the smallest manageable element of a picture represented on the screen.
• Pixel dimensions are the horizontal and vertical measurements of a picture expressed in pixels.
• The pixel dimensions could be determined by multiplying both the width and the height by the dpi.
• The maximum number of different colors that may be present in a color image is calculated by $2^n$.
• Here n = 16 So the maximum no of different colors represented in a 16-bit color image is 216.
