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。

Cavities with mirrors spaced specifically to amplify red, blue and green light are grouped in bunches of three, each of which corresponds to a single dot, or pixel, on the display.

为增强红蓝绿光，镜子会隔成特定间距，其空腔分为三束，每束相当于显示屏上的一个单点，或像素。

With your selected pixel coordinates and a single-layer base reflectivity map, the logical process for detecting precipitation near a spot on the map is straightforward.

使用选定的像素坐标和单层基本反射率图，检测地图中某个场所附近的降水的逻辑过程将十分简单。

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.
