1. A light sensor chip, comprising:
a light sensor, configured to detect light using a first exposure time to generate a first image in a first operating mode; and
a processor, electrically coupled to the light sensor, and configured to
control the light sensor to detect light using a second exposure time, longer than the first exposure time, to generate a second image in a second operating mode, wherein the processor is configured to determine the first operating mode or the second operating mode according to an image parameter of the first image, and the image parameter comprises an image quality, and at least one of an image brightness, a gain value, and a convergence time of auto exposure, and
convert, using a pre-stored learning model, the second image into a converted image.
