Spectral resolution refers to the number of bands that an image capturing device can record. It can also be defined as the width of the bands or the range of the wavelengths of each band. In terms of digital imaging, spectral resolution is analogous to the number of channels in the image. Another way of understanding spectral resolution is the number of distinguishable bands in any given image or recording of bands.
The number of bands in black and white images is 1, while the number of bands in a color (RGB) image is 3. It is possible to capture the images of hundreds of bands, wherein the other bands provide different kinds of information about the image.
