摘要:
A system and method of capturing low-light images on a mobile device include a camera module, an image sensor, an infrared filter, and a visible light filter. The image sensor can detect a color spectrum of ambient light passed through a lens of the camera module. The visible light filter can cover a first portion of the image sensor, and the infrared filter can cover a second portion of the image sensor. A processor can be coupled to the image sensor to receive visible light data and infrared data. Visible light data can be formed from ambient light passed through the visible light filter and image sensor. Infrared data can formed from ambient light passed through the infrared filter and the image sensor. The visible light data and the infrared data are combined to form a low-light image data having enhanced brightness while maintaining color accuracy.
