Abstract
An image sensing module is provided, which includes an image sensor, a cover plate and microstructures. The image sensor has a light sensitive area for receiving incident light and a peripheral area surrounding the light sensitive area. The microstructures are directly on the cover plate. The microstructures map to and substantially cover phase detection auto focus (PDAF) pixels of the image sensor in a light incident direction respectively.
Claims20
An image sensing module, comprising:
- an image sensor having a light sensitive area for receiving incident light and a peripheral area surrounding the light sensitive area;
- a cover plate over the image sensor;
