摘要: 像面相位差AF是一种新型对焦技术,通过将图像传感器的一部分像素用像面相位差AF像素群加以置换,实现相位差检测,并用于对焦,具有对焦速度快、易于小型化的特点,具有很好的应用前景。

关键词: 像面, 相位差, 自动对焦

Abstract: Image plane phase difference auto focus is a new auto focus technology.Part of pixels in image sensor is displaced by image plane phase difference auto focus pixels groups to detect phase difference and auto focus. Because of its better speed in auto foucusing and easily being miniaturization, the technology of Image plane phase difference auto focus has bright future in application.

Key words: image plane, phase difference, auto focus
