A method for coding color images with fewer blue samples than samples of other colors. This provides a psycho visually high image quality since the human retina itself has fewer S cones than L, M cones. Applications include image and video coding with lower density of blue samples than other colors such as red and green. Another application is in single sensor multi-spectral and color cameras that use Color Filter Arrays. Sampling density is limited in Color Filter Arrays so that a lower blue sample density enables higher sample densities of other colors.
