Pixel value

From Glossary of Meteorology
(Redirected from Image level)



pixel value

The intensity of a pixel, usually an integer.

For grayscale images, the pixel value is typically an 8-bit data value (with a range of 0 to 255) or a 16-bit data value (with a range of 0 to 65535). For color images, there are 8-bit, 16-bit, 24- bit, and 30-bit colors. The 24-bit colors are known as true colors and consist of three 8-bit pixels, one each for red, green, and blue intensity.
