Question

is either the number of bits used to indicate the color of a single pixel, or the number of bits used for each color component of a single pixel. [Digital Imaging Terminology]

Answer 1

Is either the number of bits used to indicate the color of a single pixel, or the number of bits used for each color component of a single pixel.

The above define Bit depth

Explanation:

• Bit depth refers to the color information stored in an image. The higher the bit depth of an image, the more colors it can store.
• The simplest image, a 1 bit image, can only show two colors, black and white.
• Bit depth refers to the color information stored in an image. The higher the bit depth of an image, the more colors it can store.
• An 8 bit image can store 256 possible colors, while a 24 bit image can display over 16 million colors.
• For consumer/end-user applications, a bit depth of 16 bits is perfectly fine. For professional use a bit depth of 24 bits is better. This ensures a good dynamic range and better precision when editing.
• The number of bits used to represent each pixel in an image. A grayscale scanner would generally be 1 bit for monochrome or 8 bit for grayscale (producing 256 shades of gray). Bit depth is also referred to as color depth.
