ABSTRACT
Color photography was originally rare and expensive, and color images became more popular only in the middle of the 20th century. It has indeed become even more popular since yet black-and-white remains a niche market for people who use the medium for artistic purposes. Even in today’s modern era, there is importance of grayscale and black-and-white images. Since the advent of color, black-and-white connotes something nostalgic, historic and anachronistic. There are three basic and primitive techniques to convert a color image into its gray level equivalent - the lightness method, the average method and the luminosity method. Here, we propose some novel approaches of converting a color image into grayscale image, based on varying pixel depth.
