METHOD AND APPARATUS FOR SYNCHRONIZING AUTO EXPOSURE BETWEEN CHROMATIC PIXELS AND PANCHROMATIC PIXELS IN A CAMERA SYSTEM

摘要

A method and apparatus synchronize auto exposure between chromatic pixels and panchromatic pixels in a camera system. A first exposure can be determined for different chromatic pixels that detect different color light. An illumination type of a scene can be detected. An exposure ratio between the chromatic pixels and panchromatic pixels can be ascertained based on the illumination type of the scene. A second exposure can be determined for the panchromatic pixels that detect panchromatic light. The first exposure can be different from the second exposure based on the exposure ratio between the chromatic pixels and the panchromatic pixels with respect to an illumination type of a scene. Then, at least one image of the scene can be captured using the first exposure for the different chromatic pixels and the second exposure for the panchromatic pixels.

1. A method comprising:
determining a first exposure for different chromatic pixels that detect different color light; detecting an illumination type of a scene; ascertaining an exposure ratio between the chromatic pixels and panchromatic pixels based on the illumination type of the scene; determining a second exposure for the panchromatic pixels that detect panchromatic light, where the first exposure is different from the second exposure based on the exposure ratio between the chromatic pixels and the panchromatic pixels; and capturing at least one image of the scene using the first exposure for the different chromatic pixels and the second exposure for the panchromatic pixels.
