最好的信号不仅取决于它的亮度，还取决于它与背景的对比度。
The best signal depends not only on its brightness but also on how well it contrasts with the background against which it must be seen.
视频处理器引导每个电极传输出代表一个物体的轮廓、亮度和对比度的信号，信号会跳动着由光神经细胞传输到大脑。
The video processor directs each electrode to transmit signals representing an object's contours, brightness and contrast, which pulse along optic neurons into the brain.
其次，采用数值计算的方式，分析了输入方波信号与光纤束位相匹配对对比度调制传递函数的影响。
The next, the influence of phase match between input signal and line-array fiber-optic image bundles on the contrast transfer function was analysed digitally.
