Why do the rear cameras have Sony and OV?

Hello, Sony and OV you mentioned are actually manufacturers of camera sensors. Because the chip is the most important part of the camera, the camera chip is sometimes used to refer to the camera. For example, an OV camera actually refers to a camera with an OV chip, not a camera made by OV.

At present, in addition to OV and Sony, there are Samsung and aptina, and there are also low-pixel chips in China.
