This paper does some experiments and analysis on the single pixel gray value of natural images. We find that lognormal distribution can be used for the coarse and simple model of single pixel gray.

本文针对自然图象中单像素灰度值的统计规律进行实验和分析，发现对数正态分布可以对之进行粗略、简单的建模。

This arrangement makes the chip particularly suitable for image-processing, because each analogue element of the array can be made to correspond to a single pixel (one of the individual dots of which an image is composed).

Also shown is a larger, (slightly) flexible model rugged enough to take a meaty fist square in the face without blinking a single pixel.

Each mirror acts as a beam-steering device, controlling whether a single picture element (pixel) in the image is light or dark.
