补充资料：色阶及分辨率
色阶是表示显示器亮度强弱的指数标准，也就是我们说的色彩指数。显示屏的色彩丰满度和精细度是由色阶决定的。业界的标准有256色、4096色、65536色、26万色。并且彩屏手机的色阶是以16倍为基数增长的。
目前彩屏手机的色阶指数从低到高可分三个层次，最低是256色，其次是4096色，目前国内主流的是65536色。65536色即通常所说的16真彩色，已完全满足我们肉眼的识别需求；而目前国内水平最高的已达到26万色。
分辨率就是屏幕上显示的像素的个数，当然像素的个数也多也就意味着屏幕越清晰，对文字的表现锐度越高。128×160已经成为65k色屏幕的一个基本标准。
摄像头及其像素
内置摄像头内置ccd(光电荷耦合器件)，内置的摄像头一般利用手机显示屏显示影象和手机内存进行数据保存。像素则是表征摄像头拍摄能力的一个标准，它的高低决定拍摄照片的分辨率，也就是说通常情况下像素越高，拍摄出来的照片清晰度越高，现在市场上有10万像素，主流的30万像素，最高的打达到130万。
