该传感器允许延长光学动态范围，在保持不饱和明亮的场景图像领域中的阴影区域的对比度好多个斜坡设置。

The sensor allows the setting of multiple slopes for extended optical dynamic range, which maintains good contrast in shadowed regions of an image without saturating bright areas in scenes.

目的在图像工程中，图像增强方法有多种，如增强对比度和动态范围压缩等等。

Objective There are many image enhance methods in image engineering, for example contrast enhancement and dynamic range compression and so on.

此方法既扩大了图象灰度的动态范围，又使得图象中的局部对比度得到了增强。

A new contrast enhancement technique is presented, which can not only extend the dynamic scope of the image gray scale, but also increase the local image contrast.
