RGB (Truecolor) Image An RGB image, sometimes referred to as a truecolor image, is stored as an m -by- n -by-3 data array that defines red, green, and blue color components for each individual pixel. Graphics file formats store RGB images as 24-bit images where the red, green, and blue components are 8 bits each. This arrangement yields a potential of 16 million colors. …

If RGB is an integer data type, then imadjust first rescales the pixel values to the range [0, 1] by using im2double. After adjusting the contrast by mapping values between the input and output contrast limits, the function converts the output image back to the original data type of RGB.

Each RGB triplet defines a color for 1 pixel of the image. An RGB triplet is a three-element vector that specifies the intensities of the red, green, and blue components of the color.

Image Processing Toolbox™ supports binary, indexed, grayscale, and truecolor image types. In each image type, pixels are stored in different formats. For example, truecolor images represent a pixel as a triplet of red, green, and blue values, whereas grayscale images represent a pixel as a single intensity value.

I = im2gray(RGB) converts the specified truecolor image RGB to a grayscale intensity image I. The im2gray function accepts grayscale images as inputs and returns them unmodified. The im2gray function converts RGB images to grayscale by eliminating the hue and saturation information while retaining the luminance.

The color components of an 8-bit RGB image are integers in the range [0, 255] rather than floating-point values in the range [0, 1]. A pixel whose color components are (255,255,255) is displayed as white.
